What are viral studies?
A scientist that studies viruses is called a virologist. Virology is roughly divided into medical virology and research virology, although the two areas overlap significantly. Medical virologists are typically M.D.s, and are primarily interested in the transmission and effects of viruses that infect humans.
How do you test for viruses in humans?
Several types of tests may be used to check for viruses:
- Antibody test. Antibodies are substances made by the body’s immune system to fight a specific viral infection.
- Viral antigen detection test.
- Viral culture.
- Viral DNA or RNA detection test.

What are the 5 causes of disease?
Causes
- Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
- Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
- Fungi.
- Parasites.
Is viral contagious?
Like bacterial infections, many viral infections are also contagious. They can be transmitted from person to person in many of the same ways, including: coming into close contact with a person who has a viral infection. contact with the body fluids of a person with a viral infection.
