My nephews doc said he has infused hives but i cannot find an explanation to describe them. they look like measels reaction to amoxicillin has all vac?

Amoxicillin given to: A child or adolescent who has a sore throat ; fever caused by infectious mononucleosis causes a very " measly-looking" (morbilliform) rash about 100% of the time, to the point that it's pretty much diagnostic of " mono". Many drugs can cause a morbilliform rash. For further information ; photos, see http://dermnetnz.Mobify.Me/reactions/morbilliform.Html. I've not heard of "infused hives".
