Virology is a branch of biology that studies the study of abnormal viral infections, especially those that affect the reproductive system of animals. These include genital and oral infections, as well as infections affecting the bloodstream, stomach, pancreas, lungs, skin, and brain. Virology also includes studies of the immune system, especially the lymphocytes, which are responsible for controlling the spread of viral entities throughout the body. Virology is thus a field that studies all forms of abnormal viral infections, particularly those that affect humans. It also studies the causes of these abnormal viruses, how they affect the body, and how the body is able to resist and fight against them.
The scope of what is virology depends on the type of virus involved; for instance, microscopist studies only those viruses that can be transmitted through biological means, whereas epidemiological studies all types of viral entities, including those that are passed on from one generation to the next. This division of the study also allows virologists to target specific populations or ethnic groups, thus increasing the success rate of certain vaccines and treatments. Some viruses have the potential to cause certain diseases or to be associated with particular types of diseases, making it possible to treat those diseases as well.
Virology has a long history of research and study, which has resulted in many useful techniques for fighting viruses and preventing their attack on the human body. For example, in order to develop effective vaccines, virologists have been trying to isolate and study certain strains of a virus that might be responsible for causing certain diseases. As an example, in order to develop effective HIV medicine, virologists have been attempting to isolate and study the HIV capsids and envelopes that are involved in HIV infection. And with the recent advancement of molecular biology and other scientific methods, it is now possible to study the behavior of living cells, examining cellular pathways and how these pathways control and coordinate the activity of other molecules and cells in the living environment.
