HIV Rash: What It Looks Like and When It Appears
Quick answer
An early HIV rash is usually described as red, flat and slightly raised spots that appear on both sides of the body, sometimes including the face, trunk, arms, legs, palms and soles. It tends to show up within a few weeks of infection, together with flu-like symptoms such as fever and sore throat. Many other illnesses cause similar rashes, and plenty of people with HIV never get one, so a rash can't tell you whether you have HIV. Only a test can.
Does this sound like your rash?
Tick the field marks that match.
The more of these match, the more reason to test and, if you feel unwell, to see a clinician. This is not a diagnosis. Many other illnesses cause the same rash and symptoms.
A new rash is unsettling at any time, and more so if you have been worried about HIV. The honest answer is that an HIV rash exists, but it looks like many other rashes. This page explains what it can look like, when it tends to appear, and what to do next.
What does an HIV rash look like?
DermNet describes the rash of early (acute) HIV as red and symmetrical, a mix of flat and slightly raised spots, that can involve the face, palms, soles, trunk and limbs. Symmetrical means it looks similar on both sides of the body.
That is a clinical description, not a test. Other illnesses can cause a similar rash, which is why the rash alone can’t tell you whether you have HIV. HIV.gov says directly: “Don’t assume you have HIV just because of these symptoms.”
When does an HIV rash appear?
The rash belongs to the earliest stage of HIV, called acute infection. HIV.gov says that within 2 to 4 weeks after infection, about two-thirds of people have flu-like symptoms, and rash is one of the listed symptoms. The NHS gives a slightly wider range, around 2 to 6 weeks.
DermNet says the rash appears together with the general symptoms of the illness. HIV.gov lists these early symptoms:
- Fever and chills
- Sore throat
- Night sweats and muscle aches
- Fatigue and swollen glands
- Mouth ulcers
HIV.gov says early symptoms can last from a few days to several weeks. Some people have no symptoms at all.
Is an HIV rash always there?
No. Many people with HIV never notice a rash, and some never have any early symptoms. A rash also isn’t the only skin change linked to HIV. DermNet describes other rashes that occur later in people living with HIV, including intensely itchy ones. For anyone, a rash that is new, widespread and unexplained is worth showing to a clinician.
Could it be something else?
Very likely, yes. HIV.gov notes that many HIV symptoms can also be caused by other illnesses. A clinician can look at the rash, ask about your recent exposures and health, and arrange the right tests. Our page on early HIV symptoms covers the other signs in more detail.
What should I do if I have a rash and an HIV worry?
- If the possible exposure was in the last 72 hours, don’t wait for a rash. Go for care and ask about PEP. See HIV PEP: what to do in the first 72 hours.
- If it was longer ago, order an HIV test online. The CDC says a NAT should be considered for people with a recent possible exposure and early symptoms who tested negative on an antibody or antigen/antibody test.
- Repeat after the window period if your first test was soon after the exposure. A negative result taken too early doesn’t rule HIV out. See our window periods guide.
Seeing a clinician about the rash itself is sensible whatever the cause. An HIV test you order online can run alongside that, so you do not have to wait for the rash to be explained.
What can I do while I wait to be seen?
Write down when the rash started, where it first appeared and any other symptoms, such as fever or a sore throat. A photo each day can help a clinician see how it changes. Rather than relying on search results, a short visit to a doctor or urgent care can get the rash looked at, and you can order an HIV test online the same day.
What if the test shows HIV?
A rash can’t tell you the answer, but a test can. If a test does show HIV, the CDC says to find HIV care and start treatment as soon as possible, and that treatment can bring the amount of HIV in your body so low that a test can’t detect it. Getting an answer is the first step, and you can take it today.
Get care today if
- You think you were exposed to HIV in the last 72 hours, even if you feel well (PEP must be started within 72 hours)
- You have a rash together with a high fever, a stiff neck, a severe headache or confusion
- Your rash is spreading quickly, is blistering, or involves your eyes, mouth or genitals and is very painful
- You have swelling of the lips, face or tongue, or trouble breathing, which can be a sign of an allergic reaction
Call 911 for a medical emergency. Otherwise, urgent care or your doctor can see you today.
When to test
- Within 72 hours of a possible exposureGo to an emergency room or urgent care clinic and ask about PEP, an emergency medicine that can prevent HIV. Don't wait for a rash or a test. See our HIV PEP page.
- As soon as you are worried, with or without a rashHIV.gov says to get tested if you think you may have been exposed, whether you have symptoms or not. You can order an HIV test online and visit a nearby partner lab. Note the date of the exposure and check which kind of HIV test it is, since that decides whether it can detect early infection.
- After a negative result taken soon after an exposureRepeat the test once the window period for that test type has passed. A NAT (nucleic acid test) can usually detect HIV 10 to 33 days after exposure, but antibody tests can take up to 90 days. Our window periods page has the full list.
Common questions
Does an HIV rash itch?
The sources we reviewed describe the early HIV rash by how it looks and when it appears, not by itch, and itching doesn't help separate HIV from other causes. DermNet separately describes intensely itchy rashes that occur in people living with HIV, and says one of them can be the first sign in someone who feels otherwise well.
Where on the body does an HIV rash appear?
DermNet says the early rash can involve the face, palms, soles, trunk and arms and legs, and that it is usually symmetrical, meaning similar on both sides. It doesn't have to be everywhere, and where it appears can't confirm or rule out HIV.
Does an HIV rash look like mosquito bites?
You can't tell from a description or a photo. The early rash is described as a mix of flat and slightly raised red spots, which many other rashes also look like. If you were exposed to HIV and have a new rash, order an HIV test online instead of trying to match the look.
Can I have HIV without a rash?
Yes. HIV.gov says about two-thirds of people have flu-like symptoms 2 to 4 weeks after infection, and that some people have no symptoms at all. A rash is only one possible symptom.
How long does an HIV rash last?
We couldn't find an approved source that gives a duration for the rash itself. HIV.gov says early symptoms overall can last anywhere from a few days to several weeks. Feeling better or the rash fading does not mean HIV is gone.
