  • Practice good hygiene: Wash your hands frequently with soap and water, and avoid touching your eyes, nose, and mouth to prevent the spread of the virus.
  • Avoid close contact with people who are sick: Maintain a distance of at least 6 feet from people who are sick with influenza to reduce the risk of transmission.
