Hello. Several weeks ago, my husband was diagnosed with Mono. He has been fine for several weeks, and I never developed any symptoms. The past 4 days, our 8 month old has had a fever 38.2-39.1, and today he is afebrile and has a german measles looking rash on his neck, trunk, arms and pelvic area. His other symptoms are mild runny nose and subtle cough. Could he have Mono? Should he be tested?
