A national study has revealed striking differences in hepatitis A exposure across Southern states, with Kerala standing out as having dramatically lower infection rates compared to its neighbours.
Health
The comprehensive study found that the national average shows 90 percent of young Indians have been exposed to hepatitis A virus (HAV).
Health
South Indian states present a complex picture that mirrors the country’s broader epidemiological transition.
Health
Kerala, often hailed as India’s most developed state in terms of human development indicators, recorded the lowest hepatitis A seroprevalence nationally at just 44.8 percent.
Health
This finding places the state in the “low endemicity” category, a classification shared only with West Bengal among the 21 states studied.
Health
Other South Indian states – Karnataka, Andhra Pradesh, Tamil Nadu, and Telangana – all fall into the “intermediate endemicity” category, though with varying prevalence rates.
