Overview of Viral Infections Induced Oxidative Stress and Its Management by Using Antioxidant

Virology is the study of viruses, including the structure of viruses, the method of viral replication that is a lytic or lysogenic cycle in bacteria, and the interaction between the host and the virus, and finally, they produce infectious disease in that host.The frequent cause of viral infection is common in people of all ages, but their spectrum of illness is varied.Those people who have suppressed or deficient immune systems have a higher risk of severe viral infectious disease.Not only for human beings but they also can infect most organisms such as bacteria, fungi, vertebrates, plants, blue-green algae etc., When viral infection occurs produces two types of damage in cells that is direct cell damage and indirect cell damage.Direct cell damage from cell energies is diverted, macromolecular synthesis is affected, interferon defense mechanisms are inhibited, etc., And indirect cell damages from viral genomes are integrated, in host genome induction of mutation occurs, inflammation occurs, etc., Oxidative stress will be produced during cell damage that time antioxidants are very important for normal homeostasis of cells and organisms, because oxidative process in infected cell which promotes viral replication, induce cell apoptosis, and decrease cell proliferation.In this review, I concluded that when oxidative stress occurs leads to an increase in the production of free radicals that relative to oxygen and nitrogen species cause delays in the cellular process during wound healing, and the cells are infected by viruses frequently, so one of the treatment is taking proper antioxidant which helps to restore the reducing condition of infected cells.
