Which of the following is a common treatment approach to manage HIV infection?

Antiretroviral therapy (ART) is the standard and most effective treatment approach to manage HIV infection. This therapy involves the use of a combination of HIV medicines taken daily to control the virus, thus preventing its replication and helping to keep the immune system functioning as well as possible. By effectively suppressing the viral load in a person's body, ART can significantly reduce the risk of transmitting the virus to others and can improve the quality and length of life for those living with HIV.

Antiretroviral medications work by targeting various stages of the HIV life cycle, which helps to maintain a low level of the virus in the blood. When taken consistently, ART can lead to viral suppression, a state where the amount of HIV in the blood becomes undetectable, which is crucial in managing the infection and preventing progression to AIDS.

Other treatments like chemotherapy, surgery, or radiation therapy are not applicable to the management of HIV as they are typically used for cancer treatment or other medical conditions rather than managing viral infections. Such interventions do not address the specific mechanisms of HIV nor do they provide the essential viral suppression needed for those living with HIV.
