Abstract
Background There have been over 30 million cases of COVID-19 in India and over 430,000 deaths. Transmission rates vary from region to region, and are influenced by many factors including population susceptibility, travel and uptake of preventive measures. To date there have been relatively few studies examining the impact of the pandemic in lower income, rural regions of India. We report on a study examining COVID-19 burden in a rural community in Tamil Nadu.
Methods The study was undertaken in a population of approximately 130,000 people, served by the Rural Unit of Health and Social Affairs (RUHSA), a community health center of CMC, Vellore. We established and evaluated a COVID-19 PCR-testing programme for symptomatic patients—testing was offered to 350 individuals, and household members of test-positive cases were offered antibody testing. We also undertook two COVID-19 seroprevalence surveys in the same community, amongst 701 randomly-selected individuals.
Results There were 182 positive tests in the symptomatic population (52.0%). Factors associated with test-positivity were older age, male gender, higher socioeconomic status (SES, as determined by occupation, education and housing), a history of diabetes, contact with a confirmed/suspected case and attending a gathering (such as a religious ceremony, festival or extended family gathering). Amongst test-positive cases, 3 (1.6%) died and 16 (8.8%) suffered a severe illness. Amongst 129 household contacts 40 (31.0%) tested positive. The two seroprevalence surveys showed positivity rates of 2.2% (July/Aug 2020) and 22.0% (Nov 2020). 40 tested positive (31.0%, 95% CI: 23.02 − 38.98). Our estimated infection-to-case ratio was 31.7. Conclusions A simple approach using community health workers and a community-based testing clinic can readily identify significant numbers of COVID-19 infections in Indian rural population. There appear, however, to be low rates of death and severe illness, although vulnerable groups may be under-represented in our sample. It’s vital these lower income, rural populations aren’t overlooked in ongoing pandemic monitoring and vaccine roll-out in India.

Abstract
BACKGROUND & OBJECTIVE Vaccine policy depends on locally relevant disease burden estimates. The incidence of Haemophilus influenzae type b (Hib) disease is not well characterized in the South Asian region, home to 30 per cent of the world's children. There are limited data from prospective population incidence studies of Hib in Asia, and no data available from India. We therefore carried out this study to assess the burden of Hib meningitis in India. METHODS A prospective surveillance study was carried out during 1997 and 1999 in hospitals for cases of Hib meningitis from 5 administrative areas of an Indian district (Vellore, Tamil Nadu) with 56,153 children under 5 yr of age, over a 24 month period RESULTS Ninety seven cases of possible meningitis (> 10 WBC/microl in CSF) were reported, an annual incidence of 86 per 100,000 (95%CI 69 to 109) in 0-4 yr old children, and 357 per 100,000 in 0-11 month infants. Eighteen had proven bacterial meningitis, an annual incidence of 15.9 per 100,000. Eight CSF had Hib by culture or antigen testing, an annual incidence of 7.1 per 100,000 (95%CI 3.1 to 14.0) in children 0-59 months. In infants 0-11 months of age, the incidence of Hib meningitis was 32 per 100,000 (95%CI 16 to 67) and in the 0-23 month group it was 19 (95%CI 8 to 37). INTERPRETATION & CONCLUSION Our data are the first minimal estimate of the incidence of Hib meningitis for Indian children. The observed incidence data are similar to European reports before Hib vaccine use, suggest substantial disease before 24 months of age, and provide data useful for policy regarding Hib immunization.

Abstract
BACKGROUND Inefficient civil registration systems, non-report of deaths, variable standards in certifying death and the legal and social consequences of suicide are major obstacles to investigating suicide in the developing world. OBJECTIVE The aim of this study was to prospectively determine the suicide rate in Kaniyambadi Block, Tamil Nadu, South India, for the years 2000-2002 using verbal autopsies. METHOD The setting for the study was a comprehensive community health programme in a development block in rural South India. The main outcome measure was death by suicide, diagnosed by a detailed verbal autopsy and census, and birth and death data to identify the population base. RESULTS The average suicide rate was 92.1 per 100,000. The ratio of male to female suicides was 1:0.66. The age-specific suicide rate for men increased with age while that for women showed two peaks: 15-24 years and over 65 years of age. Hanging (49%) and poisoning with organo-phosphorus compounds (40.5%) were the commonest methods of committing suicide. Acute and/or chronic stress was elicited for nearly all subjects. More men suffered from chronic stress while more women had acute precipitating events (chi2 = 4.58; p < 0.04). People less than 44 years of age had more acute precipitating events before death while older subjects reported more chronic stress (chi2 = 17.38; p < 0.001). CONCLUSION The study replicates findings of an earlier study from the area. The suicide rate documented in this study is very high and is a major public health concern. There is a need for sentinel centres in India and in developing countries to monitor trends and to develop innovative strategies to reduce deaths by suicide.

Abstract
Coinfection with HBV and HCV may lead to serious consequences. The present study was done to find out the prevalence of coinfection in patients with chronic liver disease. From patients with hepatitis and chronic liver disease 1673 samples were received and analysed for HBsAg by ELISA. 1342 samples were analysed for anti HCV by third generation ELISA. 493 samples positive for HBsAg were also analysed for Anti HCV to see the prevalence of coinfection. 15(3.0%) were found positive for both HBsAg and anti HCV. Out of 15 patients with coinfection 4 (26.6%) had HCC. Prevalence of HCC in patients with coinfection was higher than either infection alone i.e. HBV-9.1% and HCV-16.5%.
