Not relevant.: You have mentioned three problems which have no relation to each other. Autism is basically how her mind is arranged and is a disorder of thinking, senses and language. Mrsa infections are staph and hers sound like they are skin related. Finally URI is a virus infection of the nose, throat, ariways or sinuses.

Possible: Possible, but it has nothing to do with her autism.
