  • Masking and Screening Guidelines
    Please wear a mask or face covering when you come for your in-person visit.

    Don't worry, we'll be wearing them too!

    Please do not wear a mask with valves or vents. These protect you but don't protect others.


    Everyone will be screened for illness before entering CHA buildings.

    You will be asked questions about COVID symptoms (fever or chills, shortness of breath, cough, fatigue, muscle or body aches, headache, loss of taste or smell, sore throat, congestion or runny nose, nausea, vomiting or diarrhea.)

    If you are feeling sick, or have been near someone who you know has COVID-19, please call us before your visit. Your care team may give you advice over the phone or ask you to be seen at a different location.


    Keeping your hands clean is one way to stop the spread of illness.

    You will be asked to wash your hands or use hand sanitizer when you enter any CHA building.
