Stopping the Spread of COVID-19

…

Wash your hands for at least 20 seconds with soap and water or hand sanitizer that contains at least 60% alcohol often (especially after touching common surface areas, using the bathroom, shaking hands, and other social interactions). Avoid large crowds, crowded public places, and maintain at least 6 feet of distance between yourself and others, especially if they are coughing or sneezing. This is known as social distancing. If you are older or have underlying medical problems, take extra care to avoid these situations, including nonessential air travel or cruises. Avoid touching your eyes, nose, and mouth with unwashed hands, because contaminated hands can transfer virus to these areas and make you sick. If you are sneezing or coughing, cover your mouth and dispose of tissues after used once. Avoid shaking hands when greeting others. Disinfect surfaces that are used regularly, using household sprays or wipes. Unless you have respiratory symptoms, are a health care worker, or are in close contact with or caring for someone with COVID-19, wearing a medical mask is not indicated. Wearing gloves in public is not effective protection from COVID-19, because gloves can be contaminated. Frequently washing your hands is the best way to protect yourself and your loved ones.
