A virus is defined as an agent that is infectious, which can replicate inside living cells. It has the potential for infecting plants as well as microorganisms, which includes archaea as well as bacteria. The science, which deals with study of virus, is called virology.
Antiviral agents are actually a kind of drug, which is used for controlling or treating infections caused by viruses. They perform their action by inhibiting production of virus through different ways. The possible ways involve prevention of replication of the viral genome, blocking entry inside host cells and inhibit protein synthesis, and viral assembly.
Cidofovir is defined as an antiviral medication that is injected and is used for treating CMV (cytomegalovirus infection). It is a kind of infection that is found in the eyes of people suffering from AIDS (acquired immunodeficiency syndrome).
Some of the side effects of cidofovir are fever, sore throat, or chills. Few of the minor side effects involve enhanced urination, decreased vision, and headache, loss of appetite, vomiting, nausea, and diarrhea.
