what could or should be done...
They are saying to take the same precautions as you would for a cold or flu.
Get plenty of rest.
Eat a healthy diet.
Avoid excess sugar and alcohol.
Avoid crowds (malls, stadiums, airports, etc) and closed population (prisons, dormitories, nursing homes, any place with re-circled air).
You couldn't get me on an airplane right now for love nor money.
Wash your hands for at least 20 seconds with soap.
Avoid touching your face.
