Thank you for the query.
Yes, it sounds like some viral infection. Fever
and other symptoms indicates that. Rash
is also characteristic for some viruses. It should last few days. If you have also some leg swellings, allergy
should be considered.
I suggest you to start probiotic
intake and have mild diet. If the rash will go away in few days, no further action is necessary. Otherwise you should visit your doctor.
Hope this will help.
