What is likely to help prevent the flu from spreading through a school?

To prevent the flu from spreading through a school, it's important to promote good hygiene practices, such as regular handwashing with soap and water, and encouraging the use of hand sanitizers. Implementing vaccination campaigns can also be effective in reducing flu transmission among students and staff. Additionally, maintaining clean and sanitized environments, along with promoting proper respiratory etiquette—like covering sneezes and coughs—can further help minimize the risk of spreading the virus. Finally, encouraging students who are sick to stay home can significantly reduce outbreaks.
