Hepatitis is caused by blood borne pathogens. The pathogens themselves conveniently share similar names to the type of hepatitis they cause: The pathogen that causes Hepatitus A is known as the Hepatitis A Virus (HAV), the pathogen that causes Hepatitus B is known as the Hepatitis B Virus (HBV) and the pathogen that causes Hepatitus C is known as the Hepatitis C Virus (HCV).
Hepatitis C is the most common chronic blood borne pathogen in the United States. Hepatitis Dcan be found in the blood, semen, vaginal fluids, and other body fluids of people who are infected. Hepatitis B is transmitted through blood and infected bodily fluids.
The hepatitis B illness is caused by the hepatitis B virus, a species of the genus Orthohepadnavirus.
The two blood borne diseases most prevalent in the United States are HIV and Hepatitis.
In the past, people have contracted hepatitis C through blood transfusions
Hepatitis B
BLOOD THAT IS donated, is screened for anything that can be passed on to anyone receiving blood. Including: hepatitis A, B, & C, HIV, STD's, any bloodborne pathogen that can be passed on and make the person receiving the blood sick.
Hepatitis B & C are in the blood.
Hepatitis is a blood-born pathogen, so the answer to this depends on how well the whole blood or blood components are stored (excluding gammoglobulin, which doesn't transmit Hep C). If the blood is properly stored, the lifespan is, as with most if not all blood born pathogens, very long indeed. If the Hep C entirely dessicates, it dies, as it does if heated or exposed to bleach or other disinfectants (outside the body of course). It does however survive quite well during the time it takes to share needles (one modality of contagion). When dealing with the risk of Hep C transmission, one uses blood born pathogen protocols.
Hepatitis C
No. Hepatitis C is spread via blood-to-blood contact. So unless both persons have bleeding hands, the answer is no.
No white blood cells are not pathogens, they protect the human body from pathogens.
