I am afraid that you cannot get a clear answer to this question on the free forum for the simple reason that your question is location-specific. Any virus would be strictly limited to your locale, and not be a global phenomenon. If you wish, you can re-post this question mentioning your location so that the right person can reply to it. However, even if it is some form of virus, the treatment is not going to change other than applying calamine
and using an antihistamine for itching.
