My question is, it's been a couple of weeks since my neighbor has had the Bacterial Meningitis. Her husband came over to talk to me and shook my hand when he came over. It was only after he shook my hand and then told me about his wife. He said that he had to take some pill to keep him protected from getting it and that it was a "one time pill" first of all, is there really such a thing as a one time pill? If so, how long does it stay in the body? My question is, should I be concerned because he shook my hand?? I know that they say hand washing, hand washing, hand washing and hand washing is so important but if someone has that bacteria on their hands is it really as simple as washing with soap and water? Thanks to all who can help!
