What are viral infections?
Viral skin infections are caused by viruses. The virus finds ways to stay in the body and may remain dormant, only manifesting at different times, so that lesions can recur. This is often observed with warts and herpes. Even when a lesion is completely treated, total clearance of the virus may not be achieved.
There are also many nonspecific viral rashes that can be accompanied by fever, headache, and even general lethargy. These rashes develop rapidly and are blotchy in appearance.
