The ability of a virus to cause disease is referred to as its "pathogenicity." This term describes the virus's capacity to infect a host and lead to harmful effects, which can vary in severity depending on factors such as the virus's characteristics and the host's immune response. Pathogenicity is often assessed in terms of the virus's virulence, which indicates the degree of harm it can cause.
AIDS is caused by a virus called HIV. This virus attacks the immune system especially the T cells. It destroys the body's ability to fight off infections.
