Hi Thanks for your query Your husband seem to be developing a vasculitic skin rash. All the sites that you have mentioned are the sites commonly involved in such reactions. Firstly let me assure you that such a rash is non contagious in nature. So do not worry about transmitting it to your child. Now it is important to find out the cause of the skin rash. Find out if there is any history of intake of any drugs in the week prior to the development of the skin rash. Especially drugs like pain killers, antipyretics or antibiotics are the common offending agents in this case. Also was there history of any illness prior to the development of the rash, anything like cough or cold or an upset abdomen. Now regarding the treatment, he should apply a topical steroid cream , something like clobetasol over the affected area atleast twice a day. Take oral antihistamines to relieve the itching. Hope it helps Dr Geetika Paul
