Question

Discuss the different ways in which communicable diseases spread from person to person.

Answer 1

Communicable diseases spread from one person to another through various means. These are:

1) Through air: When a person suffering from cold or flu sneezes or coughs, germs are released that spread through the air.
2) Through contaminated food and water: When houseflies sit on garbage, germs stick to their bodies. When these houseflies sit on uncovered food or water, they contaminate the food or water by transferring the germs.
3) Through mosquitoes: Mosquitoes such as the female Aedes carry germs that cause dengue fever.
4) Through cuts and wounds: Microbes also enter our body through cuts or wounds.
5) Through direct contact: Diseases such as chickenpox can spread through direct contact from an infected person.
