Virus; Viral Infection Types, Symptoms, Treatment

Barry Rockx*

Viruses are microscopic genetic material (either DNA or RNA) fragments that are surrounded by a layer of protein. A fatty "envelope" coating is also available for certain viruses. In their own, they are unaware of reproducing. Viruses are dependent for their own survival on the species they infect (hosts). Viruses do get a bad name, but for humans, plants, wildlife, and the environment, they still serve several significant roles. Such viruses, for instance, shield the host from other pathogens. By passing genes across various organisms, viruses often participate in the process of evolution. Viruses are used by scientists in scientific science to inject new genes into cells. They think about disease-causing (pathogenic viruses such as the common cold, pneumonia, chickenpox, human immunodeficiency virus (HIV), SARS-CoV-2 and others when most people hear the term 'virus'. Many parts of the body, including the reproductive, immune, and gastrointestinal systems, may be infected by viruses. The liver, brain, and skin may also be affected by them. Analysis shows that in many tumours, viruses are also involved.
