Ciao,

The best thing you can do is try to prevent getting the virus. Wash your hands often, and do not touch your face. Take your shoes off at the door. Keep all surfaces as clean as possible. If you can, avoid the trains and metro or any crowded places.

Have extra food, water, toiletries, and medications in case of quarantine. Stay informed, do not panic. I am not a medical professional, but those are the steps I am taking. Take care.
