"Close contact" refers to being in close physical proximity to another person, typically within a distance of about six feet. This term is often used in health contexts, especially during the spread of infectious diseases like COVID-19. Being in close contact can increase the risk of transmitting germs or viruses, as respiratory droplets can easily travel between individuals. In many situations, close contact can occur in various settings, such as at home, workplaces, or social gatherings. It is important to be aware of close contact guidelines to help prevent the spread of illnesses, especially during outbreaks or pandemics.
