Hello, possible trigger warning, you have been warned.

I went to Bio class today and a kid sat next to me. Halfway through he gets up and v* in the trash can 10 feet away from me.. Will I get the stomach bug? When it happened my mouth was closed shut. I haven't touched any of his things or him. The trash can was taken out around 3 minutes after it happened. I washed my hands several times after with soap and hot water. I'm so scared, it has been almost 12 hours since, and my fear is that I'll wake up and v*, is this possible? Thank you.
