Information and Advice HIV Are there any symptoms of HIV? The symptoms of a recent infection with HIV can differ from person-to-person and some people may not get any symptoms at all. Around one to four weeks after becoming infected with HIV, some people will experience symptoms that can feel like flu. This may last up to two weeks and you may only get some of the flu symptoms such as fever, body rash, sore throat, swollen glands, headache or fatigue – or none at all. The only way to know if you have HIV, is to have an HIV test.
