I have an intense fear of vomiting and the stomach flu in general.  I havent been around anyone who is sick, but I am still worried about catching something.  Is it less likely to catch a stomach bug without being in close personal contact with a sick person?
Hi, Welcome to Chat Doctor! Stomach bugs are usually spread by Faeco-oral route. That is, a sick person emits out the bug or its cysts in his stools. These are carried by vectors such as housefly to new food, which when consumed by a person makes hi, infected as well. Now, there is no reason to be worried about catching the stomach bug, specially if no one in your household has it. Just taking few simple precautions will help you in preventing it
