If I have symptoms of COVID-19, will using CPAP spread the virus to others?

Current evidence suggests that COVID-19 spreads from an infected person through:

• Respiratory droplets generated when you cough or sneeze
• Close, prolonged personal contact, such as touching or shaking hands
• Touching something with the virus on it, then touching your mouth, nose or eyes before washing your hands

However, there is some concern that using CPAP could spread the virus through the exhalation port, which allows carbon dioxide to escape from your mask. This port also may release smaller virus-containing particles as an “aerosol,” which can remain suspended in the air for a few hours. It is possible that your bedpartner could inhale these virus particles. Therefore, it is important to sleep alone by isolating yourself in a separate bedroom. You can continue to use CPAP while sleeping in this recovery room.
