Blood and body fluid precautions are recommendations designed to
prevent the transmission of
hepatitis B virus (HBV),
hepatitis C virus (HCV), and other diseases while
giving first aid or other health care that includes contact with body
fluids or blood. These precautions treat all blood and body fluids as
potentially infectious for diseases that are transmitted in the blood. The
organisms spreading these diseases are called blood-borne pathogens.
Blood and body fluid precautions apply to blood and other body
fluids that contain visible traces of blood, semen, and vaginal fluids. They
also apply to tissues and other body fluids, such as from around the brain or
spinal cord (cerebrospinal fluid), around a joint space (synovial fluid), in
the lungs (pleural fluid), in the lining of the belly and pelvis (peritoneal
fluid), around the heart (pericardial fluid), and
amniotic fluid that surrounds a fetus.
An annoying, itchy bump may not be the only thing a mosquito leaves behind after a bite. Mosquitoes can spread diseases, too. Viruses like West Nile and chikungunya may make you feel pretty bad for a time, but they aren't life-threatening. While malaria and yellow fever can be more serious, they aren't common in the U.S.
Fortunately, when you protect yourself from mosquito bites, you prevent the sickness as well as the scratching.

Why are blood and body fluid precautions important?
Although skin provides some protection from exposure to
potentially infectious substances, it is strongly recommended that health
professionals use blood and body fluid precautions for further protection when
they are providing health care. These precautions also help protect you from
exposure to a potential infection from your health professional in the unlikely
event that you come in contact with the health professional's blood.
The American Red Cross recommends that everyone use blood and
body fluid precautions when giving first aid.
Are blood and body fluid precautions always needed?
The best practice is to always use blood and body fluid precautions, even when you can't see any blood and there's no chance that blood is present. But the precautions aren't absolutely needed if you don't see any blood when you come in contact with other body fluids, such as:
