Avoid eating food from places where hygiene is low such as stalls or restaurants built near washrooms or highways where the polluted air directly enters the food making it contaminated.

Limit going outdoors during the night or in unhygienic surroundings to reduce the chances of getting bitten by mosquitoes which can cause malaria and dengue. Use insect repellents on your clothes, hats, and socks to shield yourself from harmful mosquitoes.  

Drink boiled water. Boiling can eliminate all the dust particles, sand, bacteria, and viruses from the water and help prevent various life-threatening diseases. 

Change the water in pots or filters regularly in a day or two to avoid the risk of getting contaminated, as water contamination is an invitation to diseases like malaria, dengue, cold, throat allergies, and flu.  

Follow public health advisories and instructions from health authorities. Avoid crowded places to reduce the risk of infection spread. Seek prompt medical attention if any symptoms appear.
