As others said, wash, wash, wash, wash your hands. I got some Tamiflu on the off chance my family contracts the flu. As a Paramedic, I feel confident in catching the signs if they become infected. We are all getting flu shots and I am drilling into there heads to wash, wash, wash your hands. And do not though your face. Also, as a prophylactic, I am having all family members take an elderberry pill daily.
