Monsoon brings refreshing rains, cooler weather, and a break from scorching heat. However, it also increases the risk of several waterborne diseases—diarrhea in monsoon being one of the most common. Contaminated water, unsafe street food, and poor sanitation make this season a breeding ground for harmful bacteria and viruses.
This article explains the causes, symptoms, and treatment of monsoon diarrhea, along with easy prevention tips to stay healthy.

Power outages affecting food storage and refrigeration
