Introduction to virology and virology tests
Virologists are scientists that study viruses, which are found in astounding numbers on earth (1031!). Viruses survive only in the cells of organisms they infect, making them a parasite. Whether or not they are “living things” is a philosophical argument for a different article. One of the major reasons for studying viruses is to understand the diseases they cause in humans. Virology research has led to the development of many virology tests. It is important to diagnose as well as monitor the progression of disease of certain viruses. This means that virology tests need to be available in clinics as well as in point-of-care form to test people in areas with fewer medical resources or infrastructure. Proper diagnosis can ensure that the spread of virus can be contained and treatment can be given to those in need. A current example of a crucial virology test is SARS-CoV-2 virology tests that detect the presence of viral nucleic acid or antibodies from human samples.
