There are several things you can do, and encourage others to do, to avoid infection.
1) Keep your hands clean: Wash your hands often, especially after spending time in a public place, and before eating. Soap and water work well, but make sure to wash for at least 20 seconds and to cover all areas of your hands, including thumbs and between fingers.If soap and water are not available, use a hand sanitizer that contains at least 60 percent alcohol.
2) Avoid touching your face: As much as possible, try not to touch your eyes, nose and mouth, especially if you have not washed your hands recently.
3) Keep surfaces and objects clean: This applies particularly to things you touch all the time, such as doorknobs, countertops, faucets, and even phones. Use water and detergent or soap to clean, and disinfect with EPA-registered household disinfectants.
4) Keep your distance: Practice social distancing. Avoid close contact with anyone who is sick, or who is coughing or sneezing, and refrain from gathering with large groups.
5) Stay home: Work from home, if it is possible to do so, and avoid spending unnecessary time in crowded public locations, for example by ordering takeout or delivery instead of eating in a restaurant. In fact, many areas have closed or put restrictions on businesses such as restaurants and bars, or even taken more dramatic steps.
