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

AcademicBiologyNCERTClass 9

Becoming exposed to or infected with an infectious microbe does not necessarily mean developing a noticeable disease, because naturally, the human body develops immunity after they get infected by a disease.

During inflammation, an active immune system recruits many cells of the affected tissue to kill off the disease-causing microbes.

[Extra information:

Also during medical advancement, the vaccine is given in advance to protect the body from future infection.

Vaccines are administered by needle (injection), by mouth (orally), or by spraying into the nose (nasally).]
