Monsoon brings cool weather, greener surroundings, and relief from the heat, but this season also increases the risk of infections.
High humidity, stagnant water, contaminated food, and mosquito breeding create conditions for disease to spread.
Knowing the common monsoon illnesses, their symptoms, and prevention methods can help to protect you and your family. If the symptoms need medical attention, choosing a reliable hospital in Siliguri can help you get timely diagnosis and proper care.
Why Do Diseases Spread More During Monsoon?
Dirty Water
It mixes with sewage and dirt, which increases the risk of infection, and water becomes unsafe.
Food Contamination
Food spoils faster in humid weather, and the risk of stomach infections is high.
Germ Growth
Moist weather helps bacteria and viruses grow and spread more easily.
Waterlogging
Collected water around homes and roads creates an unhealthy environment and attracts insects.
Poor Hygiene
Wet surroundings and poor cleanliness can increase the risk of spreading germs.
Changing Weather
Sudden changes in temperature can affect the body and make people more likely to catch infections.
More Indoor Contact
During the monsoon, staying indoors in crowds can increase the risk of spreading cough, cold, and flu.

People Living in Poor Sanitation Areas
Dirty surroundings, waterlogging, and unsafe drinking water can increase the risk of infections.
