what kind of hand sanitizer are you using? The ones that only contain alcohol are useless against the sv*, which is why I'm always irritated that they even put them on cruise ships and in nursing homes. It gives people a false sense of security. Soap and water is just the best defense! It's certainly possible that you could catch it, but it's also possible you won't. All you can do at this point is keep your hygeine up. People can also shed the virus in their stool for a couple of weeks. Onset of symptoms is usually 12-72 hours, with 32-36 being about the average. Just keep washing your hands.
