Post Viral rash is different from the skin rashes. It has characteristic symptoms that are different from the other common rashes’ symptoms. Most of the cases indicate the presence of an underlying condition which causes the formation of rash.
Viral rashes are two kinds, one is a ” regular viral rash ” that is caused because of infection by viruses. The other is ” post viral rash” that appears after the infection. It can appear even after the treatment of the preexisting condition.
Actually, Most cases of post viral rash disappear in its own without any treatment. However, it may lead to abnormalities such as pain, inflammation and other related symptoms. In this case, you need to contact your doctor immediately.
It is worthy to know that children are at greater possibility to get development lupus viral rash as compared with adults.
Indeed, a post viral rash can persist for days to weeks after the virus is gone. We can’t predict totally how long it lasts. There is long acting antihistamine such as fexofenadine that can be helpful until the reaction subsides.
Generally, viral rashes can be contagious once the child has got viral rash without medication for 24 hours.
The viral rash often takes much longer time to be resolved but you can’t prevent the child from going to school. However, there is an exception which is chickenpox because it is considered as a contagious until all the lesions are dry and scanned.
Common Rashes after fever
Commonly, if you have rash after fever, one of these conditions is likely the cause.
It is the most common in children under age 2. Usually, it starts with a high fever which lasts for 3-7 days. Fever can be accompanied with other symptoms including: a cough, runny nose, diarrhea, or a loss of appetite.
When the fever ends, you will develop a slightly, pink and raised rash. This condition is not diagnosed before the fever disappears and the rash appears.

Fifth disease usually passes without issue. However, it can be a concern for children with anemia or pregnant women.
Dr.Karen Gill status “Kids develop rashes after fevers more commonly than adults. These rashes are almost always from viruses and go away without treatment. A rash that develops while a fever is still present is often from a virus, too. But some illnesses that cause fever and a rash at the same time can be more serious. Contact your doctor if your child develops a rash during a fever or is acting ill.”
If you feel there’s something to concern, it is important to contact your doctor.
