No. You can't tell whether someone has HIV by how they look or feel, and you can't rely on symptoms to know your own status. Many people have no symptoms for years. HIV.gov says the only way to know for sure is to get tested.[1][2]
Why symptoms can't tell you
HIV.gov says about two-thirds of people have flu-like symptoms within 2 to 4 weeks after getting HIV. Some people have no symptoms at all in this early stage. When symptoms do appear, they can last from a few days to several weeks.[1]
Those symptoms look like many common illnesses, such as the flu. After the early stage, a person with chronic HIV may not feel sick or have any symptoms.[1] That is why HIV.gov says you can't rely on signs and symptoms to tell whether you have HIV.[1]
Why you can't tell by looking
HIV has no visible signs that set it apart. A person living with HIV can look and feel well, and many people who have HIV do not know it yet. CDC estimates that in 2022, 87 of every 100 people with HIV in the U.S. knew their status, which means about 13 in 100 did not.[3]
People living with HIV who take treatment as prescribed can live long, healthy lives. NIH reports that people who reach and keep an undetectable viral load do not transmit HIV through sex.[4] So how someone looks says nothing about their status, and a person's status alone says nothing about your risk.
What actually protects you and your partners
- Know your own status. CDC says everyone 13 to 64 should test at least once, and people with certain risk factors should test at least once a year.[2]
- Talk about testing. Asking when a partner last tested, and sharing your own result, helps you both choose what works for you.
- Use prevention that fits your life. Options include PrEP, condoms and, for partners living with HIV, treatment to an undetectable viral load.[4]
- Act fast after a possible exposure. PEP must be started within 72 hours.[5]
