How do microbes enter in our body?

Microbes enter our body through the natural Openings in our body like mouth, lose, urinary and reproductive passages. Contaminated air, water and food can cause infections in our body. Dirty and infected utensils can be another reason for the infections.

Germs can enter our body through hand shaking or touching the body or during the sexual activities. Skin is a major barrier for the entry of the germs. The blood sucking insects or mosquitoes or mad dogs that carry germs are sometimes deadly for us. Dirty or infected syringes used for injections can also cause diseases. Viruses reproduce inside the body killing other cells in the body.
