Answer:
Sure, here are two truths and one lie about norovirus:
option 1: Norovirus is highly contagious and can spread easily from person to person, especially in crowded or closed environments like cruise ships, schools, and nursing homes.
option 2: Norovirus can survive on surfaces for days or even weeks, which makes it very difficult to control and prevent outbreaks.
option 3: Norovirus is caused by a bacterium that infects the stomach and intestines, leading to symptoms like diarrhea, vomiting, and stomach pain.
The lie is option 3 - norovirus is actually caused by a virus, not a bacterium.
