Ive had mouth ulcers for about 45 days after being exposed to the HIV virus, and Im not sure if this is a symptom of HIV or not. Can you tell me if mouth ulcers are linked to HIV? Also, what tests should I get now to check for HIV?

Mouth ulcers can be a symptom of HIV, but they don't necessarily confirm the presence of the virus. To determine if you've contracted HIV, you can take an HIV test, specifically a 4th generation antibody/antigen (Ab/Ag) test, which can detect HIV 45 days after exposure with 99% accuracy. Additionally, nucleic acid tests (NATs) can detect HIV 10 to 33 days after exposure, but these tests are typically used for high-risk exposures
