Which action helps stop the spread of influenza in the classroom?

• A. Stay home if they have a runny nose and cough.
• B. Wash their hands after using the restroom.
• C. Wash their hands after sneezing.
• D. Have a flu shot annually.

Answer: (C)

Interrupting transmission from respiratory droplets is key. When someone sneezes, droplets can land on hands; if those hands then touch surfaces or other people, the virus can spread. Washing hands after sneezing directly removes the influenza virus from the hands, breaking that spread chain right at the moment. This is a practical, in-the-moment action students can perform to protect others in the classroom. While staying home when sick and getting vaccinated are important overall strategies, they don’t address the immediate classroom transmission as directly as hand hygiene after sneezing. Use soap and water for at least 20 seconds (or sanitizer if soap isn’t available) after sneezing, and consider coughing into a tissue or elbow to further reduce droplet spread.
