My brother came down with the dreaded stomach flu on Christmas morning. I avoided him, washed my hands and used hand sanitizer. The bathroom was also disinfected regularly with bleach and Lysol spray. Regardless, I began feeling ill about 30 minutes after my brother's symptoms first started showing. This has been going on for about 3 days, now (today being the third day). I had a little diarrhea, lower stomach cramps, and nausea on and off on Christmas. For the past two days, I've only had on and off stomach cramps and nausea. Today, my mom became ill, but so far I am the only who has been sick without vomiting. Could I attribute this to the same virus, or should I accept that I am likely doomed and prepare to get sicker?
