Hi,both my parents tested positive for covid 19 and they are elderly.how can i care for them but still stay safe?

COVID 19: Do you live with them? If yes, ask them to confine themselves to their bed room with a bathroom. Ventilate the house well - open windows if possible. Keep their bedroom door closed. All should wear masks and social distance when you need to be together- keep those periods short. You can leave things at their bedroom door. Keep surfaces clean. Wash hands often.
