Heavy rainfall and localized flooding can affect water quality and increase the risk of certain waterborne infectious diseases. Drinking contaminated water or eating contaminated food may lead to illnesses such as gastroenteritis, typhoid, viral hepatitis A & E, amoebiasis, and food poisoning. Early medical evaluation is important if symptoms such as persistent diarrhea, high fever, vomiting, dehydration, or jaundice develop.
Introduction
The monsoon season brings welcome relief from the summer heat, but it also increases the risk of waterborne infectious diseases.
Heavy downpours, localized flooding, overflowing drains, and contamination of drinking water sources can expose communities to bacteria, viruses, and parasites that cause gastrointestinal and liver infections.
In areas such as ECIL, Nagaram, Kapra, AS Rao Nagar, Kushaiguda, and surrounding East Hyderabad, people should take extra care to ensure safe drinking water and hygienic food practices during the rainy season.
At Health Adda Hospitals, patients commonly seek medical care for diarrhea, vomiting, fever, dehydration, stomach pain, and jaundice during the monsoon.
