How Long Does It Live Outside the Body?
Viruses don’t “live” (i.e., reproduce) outside the body but they may exist for days on external surfaces until they degrade or find a host.
Bacteria can survive independently, but they will die if they don’t find the right environmental conditions for growth.
How Do they Enter the Body?
Direct contact with infected body fluids or lesions
Indirect contact with contaminated surfaces
Inhalation (contaminated air or droplets)
Contaminated food or water
Animal or insect bites
Diagnosed by Examining
Blood and body fluids, like cerebrospinal fluid, swabs from the respiratory tract, swabs from lesions, urine, stool and infected tissue
