What virus causes a rash?
Many types of viral infections, especially those that tend to affect children, can cause skin rashes. The most typical virus types that result in skin rashes are listed below:
- Epstein-Barr infection
All ages are susceptible to developing mononucleosis, which is caused by this virus. This virus is spread through bodily fluids including saliva, so it is known as kissing disease.
Small red bumps that can appear anywhere, including on the face and trunk, make up the rash, which is more prevalent in people taking specific antibiotics.
- Virus called varicella-zoster
It is also the cause of chickenpox infection and herpes zoster. In the case of chickenpox, it may result in a rash with fluid-filled blisters, and the chickenpox rash typically has three stages, which are as follows:
- Raised bumps on the skin that are pink, purple, red, or brown.
- The bumps turn into fluid-filled blisters.
- Blisters burst and crusts form.
Regarding herpes zoster, it manifests as a painful red rash in one area of the skin and a brown rash on dark skin when the chickenpox virus in the nerves is reactivated and transmitted through the nerves to the skin.
- rubella virus _
The question, "What virus causes a rash?" has another response. It is the rubella virus responsible for measles and rubella, as it causes a red rash on the face, and over the course of a few days it spreads to the trunk and then to the rest of the body.
Within three to five days of infection, flat pink or red spots form the rash. The immune system's recognition of the virus as it circulates through the bloodstream is what triggers the rash. To eliminate the virus, the immune cells release chemicals. These chemicals cause skin inflammation and a rash.
- Parvovirus B19 _
Slapped cheek disease, the virus that causes the fifth disease, can result in a red, itchy rash on the cheeks or extremities.
A few days later, another rash might develop on another area of the body.
- Human herpesvirus 6
This virus causes roseola or sixth disease, and the rash appears in the form of small pink spots that are usually flat, and are difficult to see in dark-skinned people. Starting on the chest and stomach, they might spread to the arms and possibly the legs before stopping.

Skin rashes can also be caused by other viruses, such as:
- Coxsackievirus , a virus from the enterovirus family ( Enterovirus genus ) , responsible for oral, hand and foot disease.
