Viral rashes, if not broken, can be bathed, and the water temperature should not be too high to avoid stimulating the rash to become red. If the rash is broken, bathing is not recommended at this time to avoid infection of the skin lesions after contact with water. A viral rash is generally self-limiting, so you can actively treat the primary disease, avoid high body temperature, drink more water, eat some soft, easily absorbed food, and some viral rashes are contagious, so you need to pay attention to isolation and rest. Viral rash can usually subside completely in about two weeks, so there is no need to be overly nervous or worried, but for serious viral infections, other diseases may occur, such as leading to myocarditis, or viral encephalitis, so extra attention should also be paid. It is best to choose a regular hospital for consultation, clear diagnosis and active treatment.
