Simple things that you can do.
2) Take some precautions like getting an oximeter. A little device that measures your oxygen level and your pulse. If you get sick and you are having trouble breathing, don't stay at home. Call a doctor. Go to the emergency room. Check your blood oxygen level. If you're sick and your blood oxygen falls below 95 and you're having symptoms, you need to be in the ER right away. Same goes for your family members.
3) Beyond that, just take it (the virus) seriously. Respect this virus. Respect how powerful it is. You don't know how your body is going to react to it, no matter how healthy or young you are.
