Opportunistic Infections and AIDS-associated Co-infections
People infected with HIV have impaired immune systems that can leave them susceptible to opportunistic infections (OIs) and AIDS-associated co-infections, caused by a wide range of microorganisms such as protozoa, viruses, fungi, and bacteria. One example of an associated co-infection is hepatitis C virus infection, which can lead to liver cancer.
Potent HIV therapies such as HAART, however, have produced dramatic responses in patients. These therapies often allow the immune system to recover, sustain, and protect the body from other infections.
Hence, antiretroviral drugs provide a way for the immune system to remain effective, thereby improving the quality and length of life for people with HIV.
