WHO (World Health Organization) and the CDC have stated that staying inside is vital to infection prevention. For any trips outside the home, masks are required—not only to comply with the law but also for your health and wellbeing as well as the health and wellbeing of others.
Experts have stated that face coverings and cloth masks can prevent asymptomatic people (those who are not showing signs of being sick) from unknowingly spreading germs and the virus that causes COVID-19 in public places, like the supermarket.
Mandatory regulations vary from country to country. For the most up-to-date information, visit your local health service website. However, as a general rule, the CDC recommends wearing cloth face coverings in public settings where other social distancing measures are hard to maintain.
