Hello, I'm sorry to hear that your son and husband aren't feeling well.
However, this question is really best answered by your family doctor or a licensed medical professional who can examine, diagnose and treat your husband and son in person.
I hope you will follow up with your family doctor as soon possible. For information purposes only, below is a link to the H1N1 special edition on Education.com. This is not a substitute for in-person care however.
