Question

Becoming exposed to or infected with an infectious microbe does not necessarily mean developing a noticeable disease. Explain.

Answer 1

The strong immune system of our body fights off the microbes. We have cells which are specialised to kill the pathogenic microbes. These cells are active when infecting microbes enter the body and when they are successful in removing the pathogen, we remain disease-free. So even if we are exposed to infectious microbes, it is not necessary that we suffer from diseases.
