Why do we have sickness?

Answer 1

Answer:

It is possible to get sick regularly when the immune system is not functioning correctly. The reason for this is that the body is unable to fight off germs, such as bacteria, properly. If an infection occurs, it can take longer than usual to recover.

Infectious diseases are caused by pathogens such as bacteria, viruses, fungi and parasites entering the body through the air we breathe, the food and drink we consume or through openings in the skin, such as cuts.
