Abstract
OBJECTIVES The aim of this study was to determine the prevalence and associated factors of inconsistent condom use among Iranian male injecting drug users (IDUs). MATERIALS AND METHODS Data came from the national Iranian behavioral survey of drug dependence, which sampled 7743 individuals with drug dependence, from medical centers, prisons, and streets in 29 provinces in Iran, in 2007. This study included all individuals who were male, IDUs, and were sexually active (n = 1131). The main outcome was inconsistent condom use which was assessed using a single item. A logistic regression was used to determine the association between socio-economic data, drug use data, and high risk injection behaviors with inconsistent condom use. RESULT 83.3% of sexually active IDUs (n = 965) reported inconsistent condom use. Based on the logistic regression, likelihood of inconsistent condom use was higher among those with a history of syringe sharing [Odds Ratio (OR); 1.63, 95% Confidence Interval (CI); 1.13-2.34], but lower among those with higher education levels (OR; 0.34, 95% CI; 0.14-0.82), those who mostly inject at home (OR; 0.09, 95% CI; 0.02-0.47), and those with a history of treatment (OR; 0.54, 95% CI; 0.31-0.94). CONCLUSION Because of the link between unsafe sex and risky injecting behaviors among Iranian IDUs, combined programs targeting both sexual and injection behavior may be more appropriate than programs that target sexual or injection behavior. The efficacy of combined programs should be, however, compared with traditional programs that only target sexual or injection behavior of IDUs.

Abstract
BACKGROUND The AIDS epidemic in Manipur, India, manifests unique features, having co-circulation of B and C HIV-1 subtypes along with recombinant forms. Manipur has the highest incidence of HIV-1 infection compared to the other states of India, but limited information is available regarding the full-length sequence of HIV-1 recombinants. OBJECTIVES To characterize the near full-length genome of a novel recombinant HIV-1 strain from an injecting drug user of Manipur. STUDY DESIGN Viral RNA, extracted from the plasma of a male injecting drug user aged 35, was diagnosed with HIV-1 infection. Near full-length genome was amplified by polymerase chain reaction using primer walking approach. Phylogenetic relationships were determined with neighbor-joining trees. The recombination break points were detected using boot scan and Simplot analyses. RESULTS This recombinant predominantly had subtype C genome and exhibited mosaic structures with subtype B insertions at three different positions of HIV-1 genome. Simplot analysis of near full-length genome sequence from the recombinant HIV-1 strain, MAN86 exhibited similarity with the sequence of C.IN.93.93IN905 in its subtype C backbone, while the subtype B insertions showed resemblance with the sequence of B.TH.99.99(TH)_C1416. CONCLUSIONS This study confirms the presence of a unique recombinant HIV-1 strain, emerging as a result of recombination between HIV-1 strains from India and Thailand.

Abstract
Genetic complexity of HIV-1 is brought about by recombination between HIV-1 subtypes which leads to the development of epidemiologically significant founder strains. In the present study, the near full-length genome sequence of an HIV-1 isolate from an injecting drug user of Manipur (India) was determined, which evidenced the presence of a novel HIV-1 BC recombinant strain. Near full-length genome was amplified by polymerase chain reaction using primer walking approach. The recombination break points were detected using bootscan and simplot analyses. This isolate exhibited a mosaic structure consisting of subtype C backbone with subtype B insertions at the upstream of pol gene (3026-3259) and the downstream of env gene which spanned till the nef gene (8183-8961). Phylogenetic relationships determined with neighbor-joining trees, revealed that the subtype C sequences clustered with sequences from Indian subtype C HIV-1 strains, and the subtype B sequences clustered with HIV-1 subtype B strains from Thailand. This finding may create a complex scenario of HIV-1 epidemic among the injecting drug users of Manipur in near future.

Abstract
Over the past 30 years, several interventions have been identified to prevent HIV transmission from HIV-infected persons to uninfected persons in discordant relationships. Yet, transmissions continue to occur. Interventions such as voluntary counselling and testing, condom promotion and risk reduction counselling are very effective in preventing transmission among serodiscordant couples but are underutilized in India despite their widespread availability. New interventions such as pre-risk exposure prophylaxis and universal antiretroviral therapy (irrespective of CD4 count) have been newly identified but face several challenges that impede their widespread implementation in India. Discordant couples in India also face certain unique socio-cultural issues such as marital and fertility pressure. We briefly review the various interventions (existing and novel) available for persons in discordant relationships in India and socio-cultural issues faced by these individuals and make recommendations to maximize their implementation.

Abstract
Global HIV-1 surveillance has led to the detection of its new recombinant forms. This study was carried out for the first time to elucidate the genetic characterization and evolutionary relationship of HIV-1 strains among injecting drug users of Nagaland, northeastern India. A total of 156 injecting drug users participated in this study voluntarily. Among them 18 were seropositive for HIV-1 (11.5%).The Heteroduplex Mobility Assay (HMA) of HIV-1 based on p24-p7 region of gag gene and C2-V3 region of env gene revealed 11 samples to be subtype C (gag/env), 1 sample as subtype B (gag/env) and 6 samples to be recombinants between subtype C and B. Also, the sequencing and phylogenetic analysis of gag (p24-p7) and env (C2-V3) genes from eighteen samples of Nagaland IDUs with different global HIV-1 strains showed the presence of Indian, African, Thai and their recombinant forms. However, more recombinant strains based on different genomic regions of HIV-1 were detected using Multiregional Hybridization Assay (MHA) where 8 out of 18 samples were found to be recombinants between subtype C and B. Thus, multiregional hybridization assay along with heteroduplex mobility assay can serve as an efficient tool in the characterization of recombination pattern among the newly emerging HIV-1 recombinants.

Abstract
Our objective was to assess HIV risk perceptions, risk behaviours and factors that may facilitate an increase in injection drug use in Calcutta. Focus group discussions and in-depth interviews were conducted with a selected group of drug users to delineate drug use patterns, languages used to express addictive and related experiences and acceptance of harm minimization messages. Results from these were used to develop a semi-structured interview instrument which was used to interview 111 drug users (76 IDUs and 35 non-IDUs) recruited from jails and detoxification centres. Secondary data of narcotic seizures for the last 5 years were collected from the Calcutta police department. Data on percentage of IDUs admitted to large detox facility in the city was also collected. Findings show that HIV/AIDS knowledge and risk perceptions were low; sharing of injection equipment was reported by 66% of the injectors; and condom use was insignificant. Non-availability, rising cost and increasing tolerance to heroin were cited as factors contributing to switch to injection. Ecological association was found between intensified police activity and an increase in: the amount of smokable heroin seized; increased injection of buprenorphine; and admission to detoxification centres. In addition to HIV, IDUs were also found to be prone to hepatitis B and C. The findings suggest an urgent need for developing and implementing community-based HIV prevention interventions targeting drug users in Calcutta.

Abstract
Manipur and Nagaland in northeast India report an antenatal HIV prevalence of > 1% and the current HIV prevalence among injecting drug users is 24% and 4.5% respectively. Through support from DFID's Challenge Fund, Emmanuel Hospital Association (EHA) established thirteen drop-in-centres across the two states to deliver opioid substitution treatment with sublingual buprenorphine for 1200 injecting drug users. Within a short span of time the treatment has been found to be attractive to the clients and currently 1248 injecting opioid users are receiving opioid substitution treatment. The project is acceptable to the drug users, the families, the communities, religious as well as the militant groups. The treatment centres operate all days of the week, have trained staff members, utilize standardized protocols and ensure a strict supervised delivery system to prevent illicit diversion of buprenorphine. The drug users receiving the substitution treatment are referred to HIV voluntary counselling and testing. As this treatment has the potential to change HIV related risk behaviours, what has been established in the two states needs to be continued and expanded with the support from the Government of India.

Abstract
HIV infection starts as an acute, systemic infection, followed by a chronic period of clinical latency, usually lasting 3 to 10 years, which precedes the eventual collapse of the immune system. It is increasingly recognized that events occurring during acute HIV infection may determine the natural course of the disease. The very dynamic events of acute HIV infection provide multiple opportunities for biologic interventions, such as anti-retroviral or immune-based therapies. Similarly, the implementation of public health measures during acute HIV infection could help control epidemics or outbreaks. Many of the dramatic possibilities for intervention in acute HIV infection remain unproved, not the least because of traditional difficulty of diagnosing patients during this early period. This article reviews the natural history, pathogenesis and clinical presentation of acute HIV infection, and suggests a diagnostic and therapeutic approach to guide clinicians dealing with patients with suspected or confirmed acute HIV infection.

Abstract
A recent occurrence of HIV-1 seropositivity among a group of injecting drug users (IDUs) in Darjeeling, a hilly district in northern West Bengal, revealed overall 11.8% HIV seroprevalence. Our study based on env (C2-V3), gag (p24-p7), and tat (exon-1) genomic regions of HIV-1 detected among this population showed that Darjeeling IDU sequences belonged to subtype C. Interestingly, the IDU sequences from Darjeeling were again found to be closer to the C strains from Manipur, a northeastern state in India, which is linked to the Golden Triangle via the Manipur-Myanmar border, rather than the IDU C sequences from Nepal, a neighboring country of India. The outgroup reference strains from different sites of IDU-driven epidemics in the world like Russia, Vietnam, Thailand, and Spain belonged to the nonsubtype C group and formed separate clusters from the subtype C cluster in our analysis. These results indicate a rapid spread of HIV-1 by possible drug trafficking along international boundaries, which might also help in the invasion of HIV-1 among IDUs of Darjeeling through the Manipur-Myanmar border of India.

Abstract
A study was conducted in June 2004 to find out the epidemiology of HIV infection among injecting drug users (IDUs) of Darjeeling District of West Bengal, eastern India. The district headquarter, Darjeeling town, also known as "Queen of Hills," is a beautiful spot situated in Himalayan West Bengal that attracts a large number of tourists each year from all over the world. Another unique feature of the district is that it has international boundaries with three countries, Nepal, Bhutan, and Bangladesh. Siliguri, the part of the district on plains, acts as a transit station for these countries as well as to the entire Himalayan region of West Bengal and neighboring state, Sikkim. It is also a transit point to all northeastern states of India: Assam, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Meghalaya, and Tripura. Two hundred twenty-eight study subjects (IDUs) were included in this community-based cross-sectional study from all four subdivisions of the district. Informed consent was obtained, and then personal interviews, followed by blood testing were performed using unlinked anonymous procedure. The study revealed that overall HIV seroprevalence among IDUs was 11.8% (n = 27; 95% confidence interval, 7.9-16.7), whereas seroprevalence of hepatitis C was found to be 47.7% (n = 97). Prevalence of HIV was higher in subjects from hill districts (13.5%) compared with subjects from the plains (9.2%). It also revealed that most IDUs (75.3%) used "brown sugar," an impure form of heroin, as their major addictive substance followed by injection norphine. Sharing of injecting equipment was found to be as high as 67% among IDUs, and sharing of drugs from common ampules was found to be 35.5% of the studied subjects (n = 93). Most subjects (96%) were found to clean their injecting paraphernalia with plain water. Most IDUs (98%) were found to inject intravenously. About 52% of IDUs visited sex workers one or more times within the last 1 year, and 15% of the interviewed subjects (n = 93) reported to suffer from sexually transmitted diseases during the same period. All the IDUs knew about HIV/AIDS. About 69% of the subjects knew that apparently healthy looking person might have HIV infection. HIV was found to be associated significantly with age of the injectors and duration of injecting practices. The study revealed the epidemic of HIV and hepatitis C among IDU populations at this bordering district of West Bengal for the first time that requires urgent intervention at local, national, and international levels.

Abstract
The majority of HIV-1 transmission in Manipur, one of the northeastern states of India, is through the sharing of needles and syringes among the injecting drug users (IDUs). A total of 28 HIV seropositive samples were used to determine the HIV-1 subtypes with respect to both gag and envelope genes. The specific regions within gag and envelope genes were amplified from PBMC DNA by nested PCR using appropriate primers. These amplicons were used in heteroduplex mobility assay followed by DNA sequencing. Phylogenetic analysis of the nucleotide sequences of respective regions showed that 89% of samples (25/28) were infected with subtype C with respect to both gag and envelope genes; however, 11% of the samples (3/28) showed subtype discordance with respect to the envelope (C2-V3) and gag (p24-p7) genomic regions. Simplot analysis of the discordant samples showed the presence of intersubtype recombination between subtype C and Thai B; two samples were found to be subtype C in envelope but Thai B in gag, whereas, one sample was found to be subtype Thai B in envelope and 'C' in gag region.

Abstract
Hepatitis B virus (HBV) genotypes differ in their potential for causing disease. Consecutive patients with chronic HBV infection (CHBV) (n=122) and blood donors (n=67) positive for hepatitis B surface antigen and HBV DNA were genotyped using polymerase chain reaction-restriction fragment-length polymorphism. The ratio of male to female subjects was significantly higher in the blood donor group than in the group of patients with CHBV (P=.0004). Among patients with CHBV, genotype D was detected in 57.3%, genotype A was detected in 18%, and genotype C was detected in 11.5%. Only genotypes D and A were detected in blood donors. The difference between the detection rate of genotype C in patients with CHBV and in blood donors was significant (11.5% vs. 0%; P=.009). Patients with CHBV who had genotype C had higher alanine transaminase (ALT) levels than those who had genotype A (P=.044) or genotype D (P=.014). Detection of genotype C in patients with CHBV and the association of genotype C with higher ALT levels may predict that this genotype has a greater potential for causing disease than other genotypes.

Abstract
An epidemiological study on substance use was carried out to assess the prevalence and pattern of tobacco, alcohol, and opium being used commonly in ethnographic diverse population of Arunachal Pradesh, India. Representative sample of 5135 people age > or =10 years were interviewed to collect information about their habit of substance use. Over all, prevalence of substance use was 30.9% tobacco (22.8% chewers and 12.1% smokers), 30% alcohol, and 4.8% opium, which vary across location, gender, race, age, education, and occupation. Though tobacco and alcohol was commonly used among all the tribes, but high alcohol use among Tangsa and Tutsa tribes reflects strong cultural belief. Religiously, opium use was low among Christian and Hindu at lower (< 1000 m) altitude, but high among Buddhist, Indigenous, and Hindu living at higher altitude. Among males, high multivariate rate ratio of opium users was seen among the population of high altitude (9.1). Moreover, it was also high among Singpho (7.1) and Khamti (9.7) tribes living in low altitude area, which shows the strong geo-ethnographic influence. Average age at initiation of alcohol use (12.4 years) was significantly lower than tobacco (17.6 years), and opium (23.3 years) indicate social acceptability of alcohol drinking at early age. Use of multiple substances and high prevalence of opium express the alarming situation of substance misuse in the region. Besides few limitations, varied results of socio-cultural and ethnic influences recalls integrated approach to break the traditional belief associated with alcohol and drug abuse from the society.

Abstract
Emergence of new addictive substances and progressive increase of 'drug abuse" has become a serious problem in many countries. Despite legal restriction and administrative control, the use of illicit drugs (like opium, heroin, proxyvan, etc.) has increased considerably in many parts of Northeast India. A sample of 1831 people (age 10 years and above) were interviewed during 1997-1998 about their drug use habits, if any, and types of substance used, in Meghalaya and upper Assam. Prevalence of substance use was 29.4% tobacco (20.5% chewers and 12.7% smokers), 12.5% alcohol, and 4.9% opium. In Meghalaya, prevalence of tobacco use was high (41.7%), which was mainly due to the large number of female chewers and male smokers. Opium and cannabis users were mainly confined in Assam close to the Arunachal Pradesh border, indicating a regional influence. Wide differences were observed in the prevalence pattern of tobacco and alcohol use across location, sex, age, education, and occupation. An association of sociodemographic factors with substance use was documented. Religion and ethnic group have significant association with tobacco use patterns but are insignificant with regard to alcohol use. Use of multiple substances and use of cannabis as a substitute for opium are the major problems indicating drug dependence. Mean ages for substance use initiation were: 18.5 years for tobacco, 21.8 years for alcohol, and 25.8 years for opium. Not with-standing the study's limitations, these findings are useful for planned prevention efforts and formulation of a specific program considering the importance of regional and sociodemographic factors.

Abstract
Genetic subtyping has been a powerful tool in tracking the global spread of HIV. To determine the HIV-1 subtypes circulating in eastern and northeastern regions of India blood samples were collected from female sex workers in Calcutta and intravenous drug users (IDUs) in Manipur. Fifty-four samples from Calcutta and 25 samples from Manipur were analyzed for HIV-1 subtyping by heteroduplex mobility assay (HMA). Twenty-six samples from these regions were sequenced. HMA and sequencing of the samples from these regions revealed subtype C as the major subtype, circulating within both eastern and northeastern regions. In Manipur, subtype ThaiB was also detected as the second major subtype. Some of the IDUs from Manipur were found to be dual infected with subtype C and ThaiB.

Abstract
BACKGROUND Across the world, drug-users (DU) have been shown to be at greater risk of contracting and transmitting sexually transmitted diseases and HIV infection. However, in the metropolitan cities of India, where drug-use patterns may uniquely vary between injection and noninjection, depending on drug availability, little is known about the risk behavior of drug-users. OBJECTIVE The objective of the study was to find out whether drug-users are more likely to practice high-risk sexual behavior compared to non-drug users. METHODS The sexual behavior of 70 drug-users, selected by snowball sampling, was compared with 128 age- and economic status-matched controls (non-drug-users), randomly selected from the same community. RESULTS Seventy-eight percent sexually active drug-users and 43% sexually active non-drug-users had multiple sex partners (P < 0.02). The average number of sex partners was significantly higher among the drug-users (P = 0.05). Anal intercourse was practiced by 25.7% drug-users and 8.6% non-drug-users (OR = 3.7; P < 0.01). The drug-users were 6.7 times more likely to visit commercial sex workers (P < 0.0001). Sexually transmitted disease prevalence was higher among the drug-users (P < 0.003). CONCLUSIONS Notwithstanding the small sample size, this study shows that drug-users practice high-risk sexual behavior more frequently. Interventions, in the form of awareness generation and prevention education programs, are required in order to reduce risk of sexually transmitted diseases and HIV transmission among drug-users.

Abstract
This review examines recent research into modalities for improving access to sterile syringes for injection drug users (IDUs) as a means to reduce human immunodeficiency virus (HIV) transmission. English language studies with empirical data were collected through Uncover reports and MedLine searches from 1998 to 2000. Although syringe-exchange programs are the most established and well-evaluated means of improving access to sterile syringes, research on alternative modalities-such as pharmacy sale, injector-specific packs, mass distribution, and vending machines-and on coverage of special populations suggests the need to pursue multiple avenues of increasing syringe availability simultaneously and, in particular, to explore modalities other than syringe-exchange programs when HIV incidence is under control. The impacts on HIV transmission of cocaine injection and sex with IDUs need to be explored further. Finally, any evidence of declining hepatitis C incidence among young IDUs might serve as a surrogate for a sharp drop in injection-related HIV risk behaviors in that population.

Abstract
In 1998, a series of five rapid situation assessments (RSA) of injecting drug use were undertaken by The Society for Service to Urban Poverty (SHARAN) covering the major Metropolitan cities of Mumbai, Chennai, Calcutta, Delhi and Imphal. The RSA determined the extent and patterns of injecting drug use (IDU), the available responses, current and planned interventions, and drug users' perceptions of injecting and sexual-related risk behaviour. The RSA was necessary as there are a lack of data on IDU in India. This has resulted in the denial of injecting drug use except for the north-eastern states by official sources, thereby affecting the inputs for IDU-related interventions. The draft assessment reports were disseminated though city workshops, held between April 1998 and January 1999. Local NGOs involved in drug treatment and HIV related interventions, government officials, and the relevant State AIDS Cells were invited to the workshops in order to contribute to final city assessment reports, so as to promote ownership and to enhance coverage. While the data obtained from the RSA were largely as anticipated, the outcome of the dissemination workshops was phenomenal.

Abstract
HIV infection among injecting drug users (IDUs) is preventable, and in order to develop appropriate interventions, an assessment was carried out at Madras, South India using the Rapid Assessment and Response Guide on Injecting Drug Use developed by WHO. Data were collected with multiple methods from multiple sources using the principles of triangulation and induction. A total of 100 IDUs were interviewed. These interviews were complemented by focus groups and observations. A community advisory board ensured community ownership and participation. Findings showed that heroin, buprenorphine, diazepam and avil were the drugs most commonly injected. The use of pharmaceutical preparations as a 'cocktail' was also prevalent. Drug injectors interviewed were males, and most (81%) were from low-income groups living in slums. Direct (69%) as well as indirect sharing (94%) was common. Such unhygienic injecting practices, and the lack of access to sterile water, contribute to the high incidence of adverse health consequences. Compared with the buprenorphine injectors, heroin injectors were more likely to share injecting equipment (P=0.0022), inject more frequently (P=0.0013), have more drug using network members (P=0.0104), frequent 'shooting' locations (P=0.002), use the dealer's place to inject (P=0.0317), and face threats of arrest (P=0.0023). Many buprenorphine injectors managed their life without serious crises, and seemed to adopt a 'natural' harm reduction response. Sexual risk behaviour was prevalent among opioid users, and a history of commercial sex was associated with daily alcohol use (P=0.0221). The assessment led to an action plan which was presented and endorsed in an advocacy meeting by key stake-holders and decision-makers. The critical importance of implementing quality, accessible, community-oriented, and effective HIV interventions with the capacity to reach the majority of IDUs is discussed. Public health responses to injecting drug use must target changes among individuals at-risk, as well as in the community and risk environment.

Abstract
OBJECTIVES Burma produces approximately 60% of the world's heroin, Laos is the third leading producer. Recent outbreaks of injecting drug use and HIV-1 in Burma, India, China, and Vietnam have been associated with Burmese and Laotian overland heroin trafficking routes. We analyzed findings from narcotics investigations, molecular epidemiology studies of HIV-1, and epidemiologic and behavioral studies of injecting drug use, to evaluate the roles that the heroin export routes play in the spread of drug use and HIV-1 in south and south-east Asia. METHODS We reviewed the medical and narcotics literature, the molecular epidemiology of HIV, and did key informant interviews in India, China, and Burma with injecting drug users, drug traffickers, public health staff, and narcotics control personnel. RESULTS Four recent outbreaks of HIV-1 among injecting drug users appear linked to trafficking routes. Route 1: From Burma's eastern border to China's Yunnan Province, with initial spread of HIV-1 subtype B, and later C. Route 2: Eastern Burma to Yunnan, going north and west, to Xinjiang Province, with B, C, and a B/C recombinant subtype. Route 3: Burma and Laos, through northern Vietnam, to China's Guangxi Province, subtype E. Route 4: Western Burma, across the Burma-India border to Manipur, predominant subtype C, and B and E. CONCLUSIONS Overland heroin export routes have been associated with dual epidemics of injecting drug use and HIV infection in three Asian countries and along four routes. Molecular epidemiology is useful for mapping heroin routes. Single country narcotics and HIV programs are unlikely to succeed unless the regional narcotic-based economy is addressed.

Abstract
Our objective is to describe recent patterns and trends in HIV and injecting drug use and to explore possible determinants of the epidemics in eastern Europe. The available data confirm a rapid spread of HIV among injecting drug users (IDUs) in the newly independent states (NIS) and suggest that all successor states of the former Soviet Union are now threatened by such epidemics, while central and southeast Europe have so far been spared from large-scale outbreaks and seem at lower risk. The future course of the epidemic in the NIS will largely depend on trends in drug injecting and on the success of harm reduction programs. Furthermore, there is potential for the further spread of HIV, via heterosexual intercourse, into the general population.

Abstract
Nationwide surveillance of HIV/AIDS from 1989 through 1996 in Bangladesh included several risk groups such as professional blood donors, patients with sexually transmitted diseases (STDs), pregnant women at antenatal clinics, commercial sex workers (CSWs), patients with tuberculosis, long-distance truck drivers, sailors, and non-residents. The population was enrolled by convenience sampling after taking informed consent. Among 70,676 persons tested, 80 (1.13 per 1000) were HIV positive. The prevalence rate was steady until 1994, and then increased rapidly. The rate among male heterosexuals was significantly higher than that in females (3.40 per 1000 versus 0.29 per 1000; odds ratio (OR) 11.60; 95% confidence intervals (CI) 6.45 to 21.16; P < 0.0001). Twelve per cent of patients with STDs had HIV. The HIV cases concentrated in 2 districts, Sylhet (25/72) and Chittagong (20/72), that border India and Myanmar (formerly Burma), respectively. Frequent movement of people of Bangladesh to India, Pakistan, Myanmar and Thailand, where HIV rates are higher, is one of the possible sources of spread of the cases. Bangladesh has the potential to avert epidemic spread of HIV at its early stage.

Abstract
To successfully stall the spread of HIV/AIDS among the ethnic minorities in India, it is imperative that we not only understand the complexity of issues in India with regard to HIV spread among ethnic groups but also comprehend that straightforward measures that might have worked in the context of other countries may not work in the Indian context. The authors present field work data and the results of interviews with 635 opinion leaders from eight 'tribal groups' from the north eastern border state of Manipur in India where a high rate of HIV infection is reported among the IDUs (intravenous drug users). The study found community support for AIDS, sex and drug education, along with an increasing perception of social vulnerability. Even though respondents perceive the threat of infection, few feel that they are personally susceptible. As HIV/AIDS prevention programmes compete with other socioeconomic conditions, the prevention blue print must be tailored to meet diverse demands in the study area and of the ethnic minorities in India.

Abstract
The article describes drug use behaviors, AIDS knowledge, risks for HIV infection, and HIV seroprevalence in drug users entering rehabilitation in Ho Chi Minh City, Vietnam. A cross-sectional, descriptive survey of all new entrants to a residential drug treatment center was conducted with linked HIV serology between July 1 and July 14, 1995. A total of 105 subjects participated: 101 men and 4 women. HIV serostatus was available for 88 subjects. Forty-seven percent (41 of 88 subjects) were HIV-positive. Median age of the subjects was 38 years. Mean length of injection drug use was 13.2 years (range, 1-27 years). The primary drug of injection was opium (96%), although 59% of subjects also injected "Western" drugs such as sedatives or tranquilizers. Eighty-two percent (86 of 105 subjects) correctly answered at least 7 of 10 AIDS knowledge questions, and only 28% (27 of 97 subjects) reported any needle sharing in the last 5 years. Seropositivity was associated with a history of previous treatment for drug abuse (p = 0.002), longer history of injecting drugs (p = 0.003), use of Western drugs (p = 0.03), and higher educational level (p = 0.05). Multivariate analysis found that the independent predictors of HIV seropositivity were history of previous treatment for drug abuse (p = 0.06) and longer history of injecting drugs (p = 0.05). Despite low levels of self-reported needle sharing and high levels of AIDS knowledge, HIV seroprevalence was high in this sample. The potential for epidemic spread of HIV in Vietnamese drug users is substantial. Risk-reduction programs and intense AIDS education projects targeting the population of drug users are necessary to control the AIDS epidemic in Vietnam.

Abstract
Since the first case of the human immunodeficiency virus (HIV) infection was documented in India in 1986, there has been an explosive increase in HIV transmission. In this review we describe the chronology of the HIV epidemic in India, preliminary information about the clinical presentation of the acquired immunodeficiency syndrome (AIDS), the biological and behavioral aspects of HIV transmission in the Indian setting, and projections regarding the future of the HIV epidemic in India. Using recent data obtained by searching the computerized literature and published abstracts, conference proceedings, and publications from the government of India, we show that India is experiencing a major epidemic of HIV transmission in high-risk populations of commercial sex workers, sexually transmitted disease clinic patients, intravenous drug users, and commercial blood donors. There is also evidence of recent spread of the epidemic from these high-risk groups to other risk groups in India, and from urban centers to rural populations. It is estimated that 1.6 million people are currently infected with HIV in India. At the present rate of transmission, India will have the largest number of HIV-infected individuals of any country in the world by the end of this decade, with more than 5 million infected individuals. Because limited data are available, comprehensive and well-designed epidemiologic surveys are urgently needed to adequately characterize the HIV epidemic in India and to help implement targeted and effective educational and prevention-oriented programs.

Abstract
India is the first country outside Africa where an HIV-2 epidemic is running in parallel to an HIV-1 epidemic, resulting in a significant proportion of double infections. HIV is spreading rapidly, mainly by heterosexual contact, but also among intravenous drug users. Genetic analyses of the HIV variants circulating in India point towards HIV-1 and HIV-2 having been introduced into the country recently.

Abstract
Since 1989, injecting drug use (IDU) related HIV infection has affected thousands of young adults in Manipur, a north eastern state of India bordering Myanmar following a similar kind of epidemic in adjoining countries like Thailand and Myanmar. During a clinical surveillance of a group of HIV positive IDUs for a natural history study at Manipur, herpes zoster (HZ) emerged as the most specific early HIV related illness (positive predictive value of 100%) in patients belonging to the age group of 12-45 years. Data collected from the dermatology departments of the two main hospitals of the state revealed that there had been an epidemic of HZ since 1990 (rate of 1990 being 11.3/1000 compared to 6.5/1000 in 1989, P value < 0.0001) among males of 12-45 years. The epidemic of HZ has been attributed to the preceding epidemic of IDU related HIV in the same age and gender group occurring 1 year earlier. HZ should be recognised as a marker condition similar to tuberculosis indicating the necessity of screening for HIV in regions where the dual problem of IDU and HIV exist in young adults.
