Pune is witnessing an unsettling surge in hepatitis A cases this monsoon season. Between March and June 2025, the Pune Municipal Corporation (PMC) recorded 57 viral hepatitis cases—more than double the 26 cases during the same period in 2024. Early July rainfall has been followed by further increases, prompting doctors to blame contaminated water and food sources.Monsoon rains clog drainage systems, allowing sewage to seep into drinking water sources. Waterborne hepatitis reaches its peak in June to October—just the monsoon season. In Pune, early rains have influenced outbreaks of viral hepatitis and typhoid: 14 cases of hepatitis in May 2025, as against a mere six in May 2024.This year's Hepatitis A cases aren't just more common—they're typically more serious. Doctors are seeing longer periods of illness and more frequent cases of severe or fulminant hepatitis—rare for Hepatitis A, which is usually mild. That would indicate a higher viral load from highly contaminated water or food.Physicians attribute much of the outbreak to tainted street food and local water supply. Illness frequently follows eating chutneys and moist preparations, the norm for street food. PMC has published advisories reminding people to use boiled or filtered water, particularly in low‑lying or construction‑afflicted areas.Hepatitis A is generally self‑limited, but in susceptible persons, it will tax the liver considerably. During monsoon seasons, India has observed increased levels of liver enzymes and cases of jaundice, particularly among children. Outbreaks in Pune have classically involved school‑aged children and adolescents most and had attack rates greater than 50% for outbreaks.PMC has not waited for the situation to deteriorate. They've begun water sampling in high-risk areas, introduced disease control cells, and opened outbreak wards. Public awareness campaigns urge boiled water, handwashing, and sanitary food handling. Vaccination against hepatitis A and typhoid is recommended by doctors where necessary.How to Keep Yourself Safe This Monsoon?During Pune's monsoon, prevention is your first line of defense:Drink only boiled or filtered water.Street food is to be avoided, particularly wet products.Practice hand and kitchen hygiene.Thoroughly wash fruits and vegetables.Hepatitis A vaccination can be given to children and high-risk adults.Why is There A Sudden Rise Hepatitis A Cases in Monsoon?Hepatitis A peaks in the monsoon season as water pollution is more frequent. Severe rains usually clog drains and contaminate drinking water sources with sewage. The hepatitis A virus, transmitted through the fecal-oral route, spreads in this way. Street food, raw vegetables, and food stored improperly can also become contaminated. Because the virus is highly infectious, even a brief slip in hygiene can lead to outbreaks, particularly in locations with unsanitary conditions and poor water quality.Can Drinking Boiled Water Prevent Hepatitis A?Yes, boiling water is the best measure to avoid hepatitis A. The hepatitis A virus is heat-sensitive and is inactivated when water is boiled for a minimum of one minute. Drinking only boiled water and refraining from ice or untreated water sources in areas of suspected contamination—particularly during monsoon—greatly lessens infection rates. It's also prudent to use boiled water for toothbrushing and washing raw food to prevent exposure.Is Hepatitis A Vaccine Recommended in Pune?Yes, medical experts advise the hepatitis A vaccine in Pune, particularly for children, those with liver diseases, and anyone who resides in or travels to regions at risk of being contaminated during the monsoon. The vaccine provides long-term protection and forms part of most pediatric immunization schedules. With Pune recently recording an increase in cases, the vaccine is even more important in preventing severe disease and reducing spread. Two doses, six months apart, are usually necessary to gain full protection.When to Consult a Doctor?Look for signs such as lethargy, nausea, pain in the stomach, and jaundice. Early liver function testing and diagnosis can avoid complications. With an increase in case severity this year, early treatment is more important than ever.
