Covid-19 prevention (by a physician)

As a physician, I usually recommand to my patients to respect some precautions like wearing masks (Nk95 if the exposition is hight, and a chir mask for the daily use), cleaning hands, respecting the distanciation if they can and avoid being in a prolonged contact (10-15) with the same person in a closed room.
Moreover, the vaccination is still a good option.
