Stages of HIV Infection

The symptoms of HIV at each stage can vary in type and severity from person-to-person and some people may not get any symptoms at all for many years. Without antiretroviral treatment, the virus replicates in the body and causes more and more damage to the immune system. Therefore, people need to start treatment as soon as possible after testing positive. Around one to four weeks after getting HIV, some people will experience symptoms that can feel like flu. These symptoms can happen because your body is reacting to the HIV virus. Cells that are infected with HIV are circulating throughout your blood system. Your immune system, in response, tries to attack the virus by producing HIV antibodies this process is called seroconversion. Once a person has been through the acute primary infection stage and seroconversion process, they can often start to feel better. In fact, HIV may not cause any other symptoms for up to 10 or even 15 years. However, the virus will still be active, infecting new cells and making copies of itself. By the third stage of HIV infection a person’s immune system is severely damaged rising to opportunistic infections.
