Get an HIV test; it is the only way to know for sure
Consider testing if you had unprotected sex
Consider testing if you shared needles or injection equipment
Consider testing if you had a recent STI
Consider testing if a sexual partner has HIV or unknown status
Consider testing if you were exposed to blood through a needle stick or blood contact
Watch for flu-like symptoms 2 to 4 weeks after exposure
Watch for fever
Watch for sore throat
Watch for rash
Watch for swollen lymph nodes
Watch for muscle aches
Watch for fatigue
Watch for mouth ulcers
Note that many people have no symptoms at all
Get tested again if the first test was done too soon after exposure
Use a clinic, doctor, urgent care, or community testing site
Use a home HIV test if available and follow the instructions exactly
Seek urgent medical care after a high-risk exposure to ask about post-exposure prophylaxis
Do not rely on symptoms alone to tell if you have HIV
