Virology is called virus analysis. A virus, on the other hand, is an organism formed by nucleic acids and proteins that reproduce inside certain living cells.

It can be said that virology is part of microbiology: specialization focused on the study of microbes (organisms that can only be seen through a microscope). Virology is also understood as a branch of biology linked to taxonomy.

Virology, in short, is responsible for studying the classification, structure and development of viruses. Among the issues analyzed, are the diseases that cause viruses, their interactions with the host, their culture and isolation mechanisms.

Researchers specializing in virology study how each virus produces an infection. When a virus infects an organism, it invades causing a certain immune response, in addition to causing the host different types of damage. Experts investigate this process and how viruses replicate (that is, they reproduce in the body).

In addition to focusing on viral pathogens, virology also studies the clinical signs that show that a virus is present in an organism and proposes methods to diagnose the infection. Simultaneously, this microbiology specialization conducts studies on vaccines and treatments against viruses. Let's look at these points of interest of virology and others, in more detail:

* viral replication cycle: the virus reproduction cycle usually consists of three phases, which are fixation and entry into the cell, eclipse and multiplication and release. It's important to note that viruses aren't composed of cells (they are acellular microorganisms ) and aren't able to replicate on their own, but must enter a cell and carry out the process there;

* viral pathogens: it's any microscopic infectious agent that's capable of causing disease or damage to another organism. Viral pathogens can reproduce inside the cells they infect, and this allows them to expand their attack exponentially in a short time. Since fungi, protozoa and bacteria of microscopic dimensions don't require a host to live or reproduce, it's possible to say that the pathogens are viruses, and that's why their study interests virology so much;

* viral immunology: it goes without saying that if viruses were not capable of causing so much damage to our organism, science would not deal with its study in such a thorough way. Getting to know the characteristics of each of them is only part, since then come the investigations of our immune system, to know how to combat them. This considerable branch of biomedical sciences and biology also studies the functioning of the immune system when the organism is healthy;

* vaccines: in relation to the previous points, virology also focuses on the development of vaccines, that is, of biological preparations capable of providing active acquired immunity to a person or animal to cope with a particular disease. In general, the vaccine includes in its composition an agent similar to the one that causes the fighting disorder. Upon contact with the immune system, the vaccine stimulates it to consider the agent as a threat and then proceed to destroy it and register it to act more quickly next time.

For all this it can be inferred that virology is part of the orbit of medicine, which is the science that, among other issues, is dedicated to studying how to preserve and restore people's health.
