Coronavirus disease (COVID-19) is a contagious infection caused by a newly identified coronavirus. The majority of people infected with the COVID-19 virus undergo mild to moderate respiratory illness and recover without the need for special care. People over the age of 65, as well as those with underlying medical conditions such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer, are more likely to develop serious illnesses. The best way to avoid and delay the spread of the COVID-19 virus is to educate yourself about the virus, the disease it causes, and how it spreads. Clean your hands regularly, use an alcohol-based rub, and avoid touching your face to protect yourself and others from infection. Since the COVID-19 virus spreads mainly by droplets of saliva or nasal discharge when an infected individual coughs or sneezes, it is important that you also follow respiratory etiquette (for example, by coughing into a flexed elbow).
