HIV (Human Immunodeficiency Virus) is a virus that attacks the body’s immune system, and one of its most concerning traits is that it can stay hidden for a long time before showing clear symptoms. In a healthy person who becomes infected, symptoms don’t usually appear right away. In fact, many people may not notice anything unusual for weeks, months, or even years.
Typically, within 2 to 6 weeks after exposure to HIV, some people develop flu-like symptoms. This stage is called acute HIV infection or primary HIV infection.
The symptoms can include fever, sore throat, swollen lymph nodes, skin rash, muscle aches, and headache. However, these signs are often mild and can easily be mistaken for a common cold or flu, so many people don’t realize they are infected.
After this early stage, the virus enters a quiet phase known as clinical latency or the chronic stage. This period can last anywhere from several years to more than a decade in a healthy individual, especially if they are not receiving treatment.
During this time, the person may feel perfectly fine and have no symptoms, but the virus continues to weaken the immune system.
This is why regular testing is so important because someone can look and feel healthy but still have HIV and transmit it to others.
