Wild-Type Virus

The naturally occurring, non-mutated strain of a virus. When exposed to antiretroviral (ARV) drugs, wild-type HIV can develop mutations that make the virus resistant to specific HIV drugs. Most people with HIV are initially infected with wild-type virus; however, some people become infected with mutated, drug-resistant strains of HIV.
