What Is an HIV Rash?
An HIV rash is a skin reaction that happens in people who have HIV. It usually looks red or purple and can feel itchy. The rash may appear soon after a person catches the virus, usually within the first two weeks. It can also happen as a reaction to HIV medicines or infections that take advantage of a weak immune system (the body’s defense system).
HIV rashes are often one of the first signs that someone has the virus, but they can also show up in the later stages of the disease. Some rashes can be very serious and even dangerous if left untreated.
What Are the Types of HIV Rash?
There are several types of HIV rashes:
-
Acute HIV rash: This rash appears when someone first gets HIV, and the immune system reacts to the virus. The rash usually shows as uneven red or purple bumps, flat spots, or blisters. It often appears on the chest, face, hands, feet, and neck.
-
HIV rashes caused by other infections: When HIV weakens the immune system, it becomes easier to catch other skin infections. These infections can also cause rashes. Some examples are syphilis (a bacterial infection), molluscum contagiosum (small skin bumps caused by a virus), herpes virus, and Kaposi’s sarcoma (a type of cancer that affects the skin).
-
HIV rashes caused by medications: Some medicines used to treat HIV or other infections can cause rashes. Usually, the rashes go away once the medicine is stopped. However, it is important to talk to a doctor before stopping any treatment.
What Are the Symptoms Shown Along With an HIV Rash?
HIV rash is often an early sign of infection and appears during the seroconversion period (the first time the body makes antibodies, which are the proteins that fight infection against HIV).
This period usually starts two to four weeks after the virus enters the body. About 50 to 90 percent of people with HIV feel flu-like symptoms at this time. Some also develop a rash on the face or other parts of the body.
Sometimes, the rash may be the only symptom, but it shows that the immune system is affected. Sometimes, rashes may appear in sensitive areas, and the affected person may notice red spots on the penis or on other genital areas. Other early signs of HIV infection that can appear along with a rash include:
-
Sore throat.
-
Fever.
-
Muscle pain.
-
Swollen lymph nodes (small lumps in the neck, armpits, or groin).
-
Night sweats.
-
Mouth ulcers (sores in the mouth).
-
Chills.
-
Fatigue (feeling very tired).
What Causes HIV Rashes?
Rashes in people with HIV can appear because of:
Acute HIV infection: The rash shows up when the virus attacks the body and weakens the immune system.
Secondary infections to HIV: HIV lowers the immune system, which makes it easier for other infections to develop.
Other infections: Rashes can also happen with many other conditions, such as:
-
Bumpy skin infection.
-
Syphilis.
-
Herpes virus.
-
Furuncles and carbuncles (boils).
-
Warts.
-
Non-melanoma skin cancer (a type of skin cancer).
-
Cellulitis (skin infection).
-
Psoriasis (skin patches with scales).
-
Seborrheic dermatitis (scaly skin, often on the scalp).
-
Bullous impetigo (blisters caused by infection).
-
Scabies (tiny mites under the skin).
-
Eczema (red, itchy skin).
-
Intertrigo (rash in skin folds).
-
Thrush (fungal infection in the mouth or skin).
-
Dermatitis (skin inflammation).
-
Kaposi sarcoma.
-
Eosinophilic folliculitis (inflammation of hair follicles).
What HIV Medications Cause HIV Rashes?
Many medicines used to treat HIV can cause rashes. Usually, these rashes are not serious and go away in a few weeks. They can be treated to reduce itching or discomfort.
The National Institute of Health (NIH) says three main types of HIV drugs may cause rashes:
- Non-nucleoside reverse transcriptase inhibitors (NNRTIs) - medicines that stop HIV from making more copies of itself.
- Nucleoside reverse transcriptase inhibitors (NRTIs) - medicines that slow down HIV replication.
- Protease inhibitors (PIs) - medicines that stop HIV from multiplying.
Some examples of HIV medicines that can cause rashes are:
-
Efavirenz (EFV): This is an NNRTI that lowers the virus in the blood. Rashes caused by EFV usually appear in the first two weeks and look like pink or red patches, sometimes with raised bumps.
-
Darunavir (DRV): This is a protease inhibitor that helps prevent AIDS and other HIV-related infections. Rashes caused by DRV may appear weeks to months after starting treatment. They can be darker, blistered, or peeling.
If a rash does not go away or comes with other symptoms such as fever, blisters, joint pain, fatigue, or rashes on the legs, it is important to talk to a healthcare provider. In rare cases, rashes can be life-threatening.
What Is Drug Hypersensitivity?
Drug hypersensitivity is an allergic reaction to HIV medicines. Mild reactions may include a rash that appears one to six weeks after starting the drug. Severe reactions can include Stevens-Johnson syndrome or toxic epidermal necrolysis (serious skin conditions with painful blisters and shedding of skin). Other symptoms may include fever, flu-like symptoms, and general discomfort.
Medicines that can cause hypersensitivity reactions:
-
Raltegravir.
-
Dolutegravir.
-
Abacavir.
-
Maraviroc.
-
Nevirapine.
How Do Rashes Change Over Time?
-
HIV rashes can look and behave differently depending on the cause.
-
Rashes that appear early in HIV infection often go away on their own as the body produces antibodies against HIV.
-
Rashes caused by long-term conditions like herpes or psoriasis may not go away completely but can improve with treatment.
-
How bad the rash gets depends on how strong the immune system is. Taking antiviral medicines can reduce the severity of outbreaks.
How to Identify HIV Rash?
HIV rashes usually appear as slightly raised areas of skin. They are often found on the trunk (chest and back) or face and sometimes on hands and feet.
-
On light skin, the rash usually looks red.
-
On dark skin, it usually looks purple.
-
After some days, an HIV rash appears, and the itchiness can occur in contact with the HIV rash. Itchiness most commonly appears on the face and chest, but can also show up elsewhere.
Conclusion
HIV rash is one of the first signs of HIV infection. It usually looks like a slightly raised area on the skin, often on the trunk, face, hands, or feet. Early rashes often go away on their own as the body makes antibodies against HIV. Chronic conditions such as herpes or psoriasis can cause rashes that do not disappear completely, but the symptoms may improve with treatment.
How severe each outbreak is depends on the strength of the immune system. HIV medicines may also cause rashes, and switching to another drug can help manage the condition. Our HIV specialist doctors at icliniq.com can help you identify and manage HIV rash. Consult them to get guided management.
Key Takeaways
-
HIV rashes are often one of the first signs of infection, usually appearing as red or purple raised spots on the skin, and they can sometimes be the only symptom.
-
Rashes can happen from the virus itself, other infections, or HIV medications, and their severity depends on the strength of the immune system.
-
Most early HIV rashes go away on their own, but persistent or severe rashes should be checked by a doctor, especially if they come with fever, blisters, or joint pain.
