Abstract
Background Iodine deficiency possesses serious threat to pregnant women and infants. During pregnancy, iodine deficiency can result in stillbirth while in infants it can lead to impaired brain development. Objective This study was conducted to assess the status of iodine deficiency among pregnant women and infants. Method Ninety seven pregnant women seeking antenatal check-up (ANC) from Chautara Hospital Sindhupalchowk were included to analyze urine iodine. Thirty one mothers and their children were followed-up for their clinical status. Additionally, the infants were assessed for their urine iodine excretion and the mothers were assessed for their awareness about iodine and iodine deficiency disorder (IDD). Result Urinary iodine excretion revealed 25.2% of pregnant women and 20% children below one year of age had insufficient iodine intake while 42.9% of pregnant women and 24% children had iodine level above normal. Almost all households were found using iodized salt, 80% respondents had heard about iodized salt, 13% mothers were aware of benefits of iodized salt, 41.9% had knowledge of iodine deficiency diseases and 38.4% cognized the source of iodine. Conclusion Though awareness about iodine and iodine deficiency disorder was satisfactory, pregnant women and children were at risk of iodine deficiency and excessive iodine disorder. Therefore, to improve health of pregnant women and newborn, their nutrition must be prioritized which ultimately will help reduce morbidity and mortality.

Abstract
Background Visceral leishmaniasis (VL) and leprosy are important public health problem in Nepal. Female Community Health Volunteers (FCHVs) play pivotal role to promote community based health services. Therefore, we designed an implementation research to assess the effectiveness of active case detection (ACD) and information education and communication (IEC) campaign of Visceral leishmaniasis cases along with leprosy cases through Female Community Health Volunteers in Visceral leishmaniasis endemic 10 Village Development Committees of both Visceral leishmaniasis and leprosy prevalent Sarlahi district of Nepal. Objective To determine the effectiveness of active case search strategy of visceral leishmaniasis along with leprosy through Female Community Health Volunteers in Sarlahi district. Method One hundred fifty one Female Community Health Volunteers of twelve Village Development Committees were oriented on detection, identification and referral of Visceral leishmaniasis and leprosy patients. They were oriented on referring the patients to district hospital for confirmatory diagnosis and treatment. The intervention was continued up to ten months after training of Female Community Health Volunteers. Data on number of Visceral leishmaniasis and leprosy patients detected and referred by Female Community Health Volunteers and detected through passively at district hospital were collected and indicators was calculated. Result Altogether 151 Female Community Health Volunteers were trained from 12 (Village Development Committees) VDCs of Sarlahi district. Their knowledge on leprosy and Visceral leishmaniasis related information subsequently increased after training. None of the Visceral leishmaniasis or leprosy cases were detected actively through Female Community Health Volunteers. However, two leprosy cases were detected through household screening. Conclusion Female Community Health Volunteers should be provided sufficient knowledge to use them in community based active case detection of Visceral leishmaniasis and leprosy.

Abstract
BACKGROUND Influenza is one of the public health burdens in Nepal and its epidemiology is not clearly understood. The objective of this study was to explore the molecular epidemiology and the antigenic characteristics of the circulating influenza viruses in Nepal. METHODS A total of 1495 throat swab specimens were collected from January to December, 2014. Real time PCR assay was used for identification of influenza virus types and subtypes. Ten percent of the positive specimens were randomly selected and inoculated onto Madin-Darby Canine Kidney Epithelial cells (MDCK) for influenza virus isolation. All viruses were characterized by the hemagglutination inhibition (HI) assay. RESULTS Influenza viruses were detected in 421/1495 (28.2%) specimens. Among positive cases, influenza A virus was detected in 301/421 (71.5%); of which 120 (39.9%) were influenza A/H1N1 pdm09 and 181 (60.1%) were influenza A/H3 subtype. Influenza B viruses were detected in 119/421 (28.3%) specimens. Influenza A/H1N1 pdm09, A/H3 and B viruses isolated in Nepal were antigenically similar to the vaccine strain influenza A/California/07/2009(H1N1pdm09), A/Texas/50/2012(H3N2), A/New York/39/2012(H3N2) and B/Massachusetts/2/2012, respectively. CONCLUSIONS Influenza viruses were reported year-round in different geographical regions of Nepal which was similar to other tropical countries. The circulating influenza virus type and subtypes of Nepal were similar to vaccine candidate virus which could be prevented by currently used influenza vaccine.

Abstract
Background Seasonal influenza is one of the increasing public health burdens in Nepal. Objective The objective of this study was to isolate and characterize the influenza virus type and subtypes of Nepal. Method A total of 1536 throat swab specimens were collected from January to December 2012. Total ribonucleic acid was extracted using Qiagen viral nucleic acid extraction kit and polymerase chain reaction assay was performed following the US; CDC Real-time PCR protocol. Ten percent of positive specimens were inoculated onto Madin-Darby Canine Kidney cells. Isolates were characterized by using reference ferret antisera. Result Of the total specimens (n=1536), influenza virus type A was detected in 196 (22%) cases; of which 194 (99%) were influenza A (H1N1) pdm09 and 2 (1 %) were influenza A/H3 subtype. Influenza B was detected in 684 (76.9%) cases. Influenza A (H1N1) pdm09, A/H3 and influenza B virus were antigenically similar to the recommended influenza virus vaccine candidate of the year 2012. Although sporadic cases of influenza were observed throughout the year, peak was observed during July to November. Conclusion Similar to other tropical countries, A (H1N1) pdm09, A/H3 and influenza B viruses were co-circulated in Nepal.

Abstract
BACKGROUND Women of reproductive age in Nepal are vulnerable to different health problems, which can jeopardize physical and mental development of fetus and mother. The aim of this study was to explore the general health status of reproductive aged women of Nepal. METHODS Household survey and health camps were conducted in selected Village Development Committees of nine districts in three ecological regions of Nepal in 2011-2012. Structured questionnaires were used to collect the required information from women of reproductive age (15 to 49 years) group. Measurement of blood pressure, anthropometry and presence of thyroid swelling, jaundice and edema of the participants were performed. RESULTS In total, 21111 women were interviewed. Women having hypertension (9.4%, n=85) and jaundice (0.9%, n=8) were predominant in the Mountain. Prevalence of Grade 2 thyroid (6.3%, n=320) was found higher in Terai. Prevalence of underweight women was significantly higher in women of Terai (26.6%, n=1235) (p<0.001). Prevalence of anemia was 26.0% (n=2165) in Hills and 24.7% (n=1232) in Terai. Among the pregnant women more than half were anemic and more underweight women were anemic (25.4%, n=619). Anemia was significantly associated with pregnancy (p<0.001), Hill and Terai ecological regions (p<0.001) and underweight women (p<0.001). CONCLUSIONS General health status of women of reproductive age is still poor. Thus, such high-risk population should be the focus of the government and concerned bodies to improve the general health status of women and children.

Abstract
This study was conducted to find out the prevalence of intestinal parasitic infection among patients attending Nepal Medical College Teaching Hospital, Kathmandu from July 2011 to February 2012. A total of 312 stool samples collected in a clean, dry screw capped plastic container were examined using the formal-ether concentration and sucrose-flotation techniques. Overall parasite positivity rate was 30.1% with significant difference between males (34.2%) and Female (26.3%) (p < 0.05). Out of total positive, 90.4% had single parasitism whereas 9.6% had multiple parasitism. Children aged < or = 5 years were found to be highly infected (35.8%), followed by 6-15 years (32.1%) and > 15 years old (26.9%). Rate of infection was significantly higher among patients from inside Kathmandu Valley (31.1%) than outside valley (17.4%) (p < 0.05). E. histolytica (38.5%) and Hookworm (10.6%) were the commonest protozoa and helminthes respectively. Other parasites detected were G. lamblia (26.0%), E. coli (1.0%), T. trichiura (7.7%), A. lumbricoides (6.7%), H. nana (5.8%) and Taenia species (3.8%). Out of total parasites detected, 65.4% were protozoa and 34.6% were helminthes. Positive rate was higher in Dalit (37.5%) and Aadibasi-Janjati (34.3%) than Brahman-Chhetri (22.6%) (p < 0.05).

Abstract
Iodine is an important micronutrient for mental growth and development. Limited information is available on the role of iodine supplementation in pregnancy and its effect on perinatal outcome. We designed intervention study to assess the effect of iodine supplementation during second half pregnancy and its effect on perinatal outcomes (maternal and neonatal health). Among 60 intervened with oral iodine tablet in pregnancy and 60 control pregnant women in Sindhupalchowk District Hospital Chautara, we assessed maternal and neonatal health after the delivery. The significant differences were found among duration of pregnancy, weight of pregnant mother before and after intervention of at least three months duration (56.1 kg vs. 59.6 kg, p < 0.001), weight of neonate (3.3 kg in intervention vs. 3.0 kg in control, p < 0.001), and thyroxin hormone (1.1 ng in intervention vs. 1.2 ng in control, p < 0.001) of women between intervened and control subjects. Therefore, regular supplementation of iodine in oral form for more than three months during pregnancy preferably during early stage will bring significant positive changes in perinatal outcomes.

Abstract
Although, when applied under controlled conditions in India and Nepal, indoor residual spraying (IRS) has been found to reduce sandfly densities significantly, it is not known if IRS will be as effective when applied generally in these countries, via the national programmes for the elimination of visceral leishmaniasis. The potential benefits and limitations of national IRS programmes for the control of sandflies were therefore evaluated in the districts of Vaishali (in the Indian state of Bihar), Sarlahi (in Nepal) and Sunsari (also in Nepal). The use of technical guidelines, levels of knowledge and skills related to spraying operations, insecticide bio-availability on the sprayed surfaces, concentrations of the insecticide on the walls of sprayed houses, insecticide resistance, and the effectiveness of spraying, in terms of reducing sandfly densities within sprayed houses (compared with those found in unsprayed sentinel houses or control villages) were all explored. It was observed that IRS programme managers, at district and subdistrict levels in India and Nepal, used the relevant technical guidelines and were familiar with the procedures for IRS operation. The performance of the spraying activities, however, showed important deficiencies. The results of bio-assays and the chemical analysis of samples from sprayed walls indicated substandard spraying and suboptimal concentrations of insecticide on sprayed surfaces. This was particularly obvious at one of the Nepali study sites (Sunsari district), where no significant vector reduction was achieved. Sandfly resistance to the insecticide used in India (DDT) was widespread but the potential vectors in Nepal remained very susceptible towards a pyrethroid similar to the one used there. The overall short-term effectiveness of IRS was found to be satisfactory in two of the three study sites (in terms of reduction in the densities of the sandfly vectors). Unfortunately, the medium-term evaluation, conducted 5 months after spraying, was probably made invalid by flooding or lime plastering in the study areas. Preparation for, and the monitoring of, the IRS operations against sandfly populations in India and Nepal need to be improved.

Abstract
BACKGROUND Very limited information is available on epidemiology of falciparum malaria in Nepal. Such information is very important for malaria control programmes. It is believed that malaria in Eastern region is imported from border districts of India and local transmission follows whereas it is indigenous in Central region. Therefore, the characteristics and risk factors of malaria are believed to be different in Eastern and Central Nepal. OBJECTIVE The objective of the study is to describe and compare the characteristics and risk factors of falciparum malaria in Eastern and Central Nepal. MATERIALS AND METHODS This cross-sectional study was conducted in falciparum malaria endemic districts of Eastern and Central Nepal, during the period 2007 to 2008. We identified and collected information from 106 patients (62 from Eastern and 44 from Central region). Patient examination, clinical and laboratory assessment were done and patients were interviewed using structured questionnaire for malaria related characteristics, risk factors and behaviours. RESULTS There were significant differences in risk factors and characteristics of falciparum malaria in the Central than the Eastern region. In the Central region, male, illiteracy and thatched roof hut were significant risk factors of falciparum malaria patients as compared to the Eastern region. Visits outside within three months, previous malaria within three months, taking antimalarial before confirmatory diagnosis were significantly higher in patients of the Eastern region as compared to the Central region. CONCLUSION Falciparum malaria in Nepal should not be seen as similar entity, and different strategies for prevention and control is needed for its diverse characteristics and endemicity.

Abstract
BACKGROUND & OBJECTIVES The information on malaria related knowledge, practices and behaviour of the people of Nepal living in malaria endemic areas are essential to develop behavioural change communication messages and for producing policy to prevent and control malaria in the country. The objective of this study was to assess knowledge, practices and behaviour of the people living in malaria endemic districts and relate with malaria control policy in Nepal. METHODS The paper utilizes data from a cross-sectional study of 1330 households conducted during December 2004 to April 2005 in rural areas of Jhapa, Kailali and Kanchanpur districts. The method used includes structured questionnaire and focus group discussions. RESULTS The results revealed that 40% respondents were illiterates. Eighty-six percent respondents have heard about malaria but only 50% responded fever with chills as the sign and symptom of malaria. Seventy-three percent responded that mosquito bite causes malaria transmission and 74% respondents considered that malaria is the fatal disease but very few have knowledge that the treatment of malaria in time can save life. More than 50% did not have information on availability of free treatment of malaria in Nepal. Still 16% were found consulting traditional healers for the treatment. The outside sleeping habit was found in almost one fourth of the population mainly in summer season indicating no knowledge about prevention of malaria. Although bednet use practice was higher, only 4% had knowledge on insecticide impregnated bednets and 23% of them practicing it. Issues regarding the proper and regular use of bednets, the quality of the bednet and use of free treatment provided by the government, since these districts are reporting high incidence of malaria. INTERPRETATION & CONCLUSION Health education must be taken into account for communities in malaria endemic areas to produce desired outcomes in malaria control.

Abstract
INTRODUCTION Visceral Leishmaniasis (VL) re-emerged in the Indian subcontinent in the mid-1970s after an almost complete absence in the previous fifteen or so years. The disease was first noted in Nepal in 1978 and, since 1980, it has been reported regularly in increasing numbers. Elimination of visceral leishmaniasis by 2015 has been identified as regional priority program in the level of high political commitment. OBJECTIVE The objectives of this study are the comprehensive assessment of information related to VL on the basis of past research studies conducted in Nepal, and an assessment of the prospects of control measures. MATERIALS AND METHODS This was time line comprehensive VL epidemiological assessment study based on the research conducted by main author during the past ten years. During the period the studies were conducted using cross sectional, case control and exploratory study design. The statistical analysis was done using qualitative and quantitative methods. RESULTS In our study in the visceral leishmaniasis endemic district, Siraha, in the population of 112,029, a total of 996 clinically suspected cases were reported (with fever of long duration and splenomegaly, with no malaria) during 1998-2002. In all, 283 subjects were found positive for visceral leishmaniasis by rK39 and 284 had positive bone marrow. There was no detectable difference in the density of Phlebotomus argentipes between high, and moderate incidence village development committees (VDC: the smallest administrative unit), but collections in the low incidence areas (in winter) were negative. P. argentipes was never numerous (maximum 4.4 females collected per man-hour), and was much less common than P. papatasi. Peaks of abundance were recorded in the March and September collections. We have found that the numbers of reported cases of visceral leishmaniasis in Nepalese villages was unaffected by indoor residual spray (IRS) indicated by parallel trends in case numbers by time series analysis in treated and untreated villages. A series of maps through ten years clearly showed that the infection can move rapidly between villages, and it is impossible to predict where transmission will occur from year to year. CONCLUSION If maximum benefit in relation to cost is the goal, it may be preferable to put all possible efforts into active case detection (ACD) with free treatment. ACD should involve the network of Village Health Workers or Female Community Health Volunteers and the rK39 dipstick test at health centre level. Surveillance of disease and vector, communication for behavioural impacts and insecticide spraying should be important component of elimination program. If IRS is to be a part of the intervention, it is essential that it is carried out effectively, both in areas where the disease has been reported and in neighbouring areas. Integrated vector management need to be monitored for its application and effectiveness for VL elimination.

Abstract
The main objective of this study is to review the HIV/AIDS status and trend in Nepal. The design of the study was retrospective in nature. Review was made of published and unpublished documents during the period 1988 to 2004. Year-wise data indicates that the cases of HIV/AIDS have been increased sharply since mid 1990s. In 1992, more than double numbers of new cases were reported than the formerly reported cumulative cases. The latest cumulative HIV/AIDS cases as of May 2004 were reported as 747 cases of AIDS and 3765 cases of HIV infections. Among total HIV/AIDS cases, clients of sex workers (57.8 percent) were predominant followed by sex workers (13.9 percent) and injecting drug users (15.6 percent). Similarly, others included housewives (10.6 percent), children (1.8 percent) from vertical transmission and blood or organ recipients (0.2 percent). Male cases (73.0 percent) were found predominant than female cases (27.0 percent). HIV prevalence among risk group population was found highest in injecting drug users (38.4 percent) followed by Female Sex Workers (4.1 percent) and migrants (3.0 percent). The risk population and HIV/AIDS prevalence has been found sharply increasing after mid 1990s. The increasing trend of the disease certainly has given pressure to focus on the use of comprehensive targeted intervention programs in risk group sub-populations.Key Words: HIV/AIDS, Trend, Risk populations, Prevalence.
