Do I have to treat everyone in the house?

Depends on reason. Please send your question to healthtap again, with details about why you might need to treat everyone in the house. Is there a head lice or whooping cough outbreak at home? For head lice and whooping cough, everyone may need to be treated (can also depend on age). Each question is seen independently by our medical experts, so each question must have enough details by itself. Thanks!
