If you have come into contact with someone who has a respiratory illness, you should monitor yourself for new respiratory symptoms or fever.

Additional precautions you can consider after exposure:

  • Wear a high-quality mask indoors as soon as you find out you were exposed to prevent the possible spread to unexposed or immunocompromised people. Data on mask use has shown that high-quality, well-fitting masks are effective at reducing the transmission of COVID-19, and that they are likely effective at reducing the transmission of flu and RSV.
  • If available to you, take an at-home test to monitor your health status and protect others.
  • If you begin to have symptoms, contact your healthcare provider and get tested to determine which infection you may have and discuss treatment and vaccine options.
