Viral infections cause a host of symptoms. For instance, the highly common flu is caused by a virus and can lead to symptoms like fever, sore throat, and muscle aches. Viruses can also cause rashes, which is called a viral exanthem rash.
Viral exanthem rashes cause spots and splotches on the skin. In many cases, rashes first appear on the face or midsection, then move to other areas of the body. Itchiness can accompany some viral rashes, but some people experience rashes without itchiness. Rashes can result from a wide variety of viruses, including:
It’s important to have new skin symptoms assessed by a doctor. An examination can help you determine the type of virus you’re experiencing, as well as rule out other conditions.
There are no specific treatments for viral exanthem rashes. In most cases, skin issues will resolve once a person’s immune system effectively fights off the virus causing the rash. How long this takes can depend on the type of virus, as well as the person’s general state of health. With something like chickenpox, it can take up to two weeks for the rash to clear.
In the meantime, doctors may recommend treatments to relieve symptoms associated with rashes, such as itching. This includes topical medications, such as ointments, as well as nonsteroidal anti-inflammatory drugs to reduce skin swelling.
