Per U.S. Department of Labor, it is always good to practice:
Frequently wash your hands with soap and water for at least 20 seconds. When soap and running water are unavailable, use an alcohol-based hand rub with at least 60% alcohol. Always wash hands that are visibly soiled.
Avoid touching your eyes, nose, or mouth with unwashed hands.
Practice good respiratory etiquette, including covering coughs and sneezes.
CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission.
