In order to avoid being in direct contact with someone who may be infected, it is important to practice “social distncing”, see below.
Social distancing: Any number of measures taken to increase the physical space between people to slow the spread of the virus. They include staying home more often, catching up with loved ones online instead of in person, strictly limiting the number of visitors to your home, and staying away from other people when you are in a public space. The WHO recommends being more than one metre (three feet) away from the nearest person, while some health experts have suggested maintaining a distance of at least two metres from others.
