Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of herpes skin infection or other viral skin infection is more. Herpes and other skin viruses cause fluid filled blisters. And they are contagious especially in close household contacts. Since you are your husband both are having similar symptoms, possibility of herpes or other skin viral infection is more. Better to consult dermatologist and get done clinical examination. You will need acyclovir tablet and other supportive drugs. Hope I have solved your query. I will be happy to help you further. Wishing good health to both of you. Thanks.
