What is infectious agent in biology?

How are infectious agents transmitted?

Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.

How are infectious diseases treated?

How are infectious diseases treated? Treatment depends on which microorganism causes the infection. If bacteria cause a disease, treatment with antibiotics usually kills the bacteria and ends the infection.
