Mumbai's April heatwave is leading to surge in gut infections
As heat accelerates bacterial growth, food spoils faster, gut infections rise and dehydration makes it worse.

What's happening?
Hospital emergency wards across Mumbai are seeing a 50% surge in gut infections. Heat speeds up bacterial reproduction in food and water — leftovers and street food become dangerous in 40°C heat. Tanker water supplied during shortages isn't always clean; heat accelerates contamination. Dehydration weakens your immune system, making you more vulnerable to infections.
Why should you care?
Summer is here and will get worse — IMD forecasts above-normal heatwaves through June. Everyone in your family is at risk, but young children, elderly people, and outdoor workers are most vulnerable. These infections are preventable with simple daily habits.
What can we do about it?
- Drink smart: 3-4 liters of water daily plus electrolyte drinks (ORS packets) to stay hydrated
- Keep food safe: Store cooked food in the fridge within 2 hours; avoid street food during peak heat hours
- Clean water matters: Filter or boil drinking water, don't trust tanker water without testing
- Hygiene first: Wash hands regularly, especially before eating and after using the toilet
- Watch for warning signs: Persistent loose stools, severe cramping, dizziness — don't self-medicate, get to a doctor before dehydration sets in
