What do retroviruses do once they have entered a host cell? Why is there little to no immune response following infection by HIV? Why is it difficult to diagnose? What is the difference between HIV and AIDS? How does HIV lead to AIDS? How is HIV transmitted? There isn't a drug to cure HIV although drugs are used to keep the viral load low to prevent regression into AIDS. Explain how these drugs work.Viruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sites
