Question
Becoming exposed to or infected with an infectious microbe does not necessarily mean developing noticeable disease. Explain.
✓
Answer
Because of strong immune system our body is normally fighting off microbes. The immune system possesses specialised cells which are capable of killing the infective microbes. These cells are active when infecting microbes enter the body and if they are successful in removing the pathogen, we remain disease - free. So even if we are exposed to infectious microbes, it does not necessary mean that we suffer from diseases.
