What is a viral exodus?

A viral exanthema is a rash associated with a virus; It can be caused by an immune overreaction or by toxins released by the virus. It usually spreads throughout the body and can vary in characteristics depending on the virus responsible. Some cases are self-limited and resolve with the virus, while others may require specific treatment. A medical provider can examine the patient to determine the cause and make recommendations to treat the underlying problem and address the rash.

Young children in particular are very prone to viral rashes. Mild skin rashes may simply cause reddening of the skin and some blemishes, while severe rashes may include large welts that can itch and ulcerate, oozing fluids and exposing underlying tissue. Chickenpox is a classic example of a common childhood illness that can cause a viral rash. As the patient recovers, the rash will begin to resolve, although some scarring may remain if the patient scratched the sores while the virus was active.

Measles, scarlet fever, staph infections, and roseola, among others, can also cause a viral rash. Some of these conditions require more aggressive treatment because they may pose a risk to the patient's health; The high fever associated with some viral infections, for example, can cause brain damage and, in cases, can lead to coma and death if not addressed. Vaccines are available for some dangerous viruses known to cause rashes, allowing patients to prevent infections and the uncomfortable rashes that sometimes accompany them.

Rashes may be itchy or painful, and a viral exanthema may require treatment with steroids and other topical ointments to reduce inflammation and make the patient more comfortable. Calamine lotion preparations and similar products can also limit itching, as can bathing in baking soda or oatmeal to soften the skin and reduce irritation. If a patient starts scratching from a rash, there is a risk of causing infection, and it may be helpful to wear long clothing or gloves at night to avoid mindless scratching.

One of the most infamous causes of a viral rash is thought to be extinct in the wild. The smallpox virus causes a rash all over the patient's body as it progresses, and the scabs from the rash can sometimes contain live viruses that can infect others. With an aggressive global vaccination campaign in the 20th century, nations worked together to eradicate this deadly disease, though samples remain in research facilities.
