Public health experts say these are the best ways to protect yourself

■ Stay home as much as possible, especially if you are over 65 or have underlying health conditions.

■ Practice social distancing. The CDC advises staying 6 feet away from others in public.

■ Feeling like you are getting sick? Don’t go to the emergency room. If you are mildly ill, stay home, check your temperature at least twice a day, and limit your contact with others in your household. Wear a face mask when you are around them.

■ If symptoms worsen, call your doctor or an urgent care clinic for advice on where to go for testing or treatment. Testing is still largely limited to those with a doctor’s order and more severe symptoms.

■ Don’t call 911 for testing. Call it only for a medical emergency, such as difficulty breathing or an extremely high temperature.
