Transmission is the risk that a person becomes infected when they come in contact with a person with COVID-19.

Doubling time refers to the time it takes for the number of hospitalized patients to double in number. Conversely, halving time refers to the time it takes for the number of hospitalized patients to halve in number.

Daily growth is the rate of change in the hospitalization from day-to-day.

Physical distancing is a reduction in close contact between people.

Wise socializing is ensuring you don’t become a link in a COVID-19 transmission chain that ends in a person becoming hospitalized or dying. This involves wearing a mask in indoor spaces, isolating yourself from others when sick, staying 2 meters apart from people outside your household, and exercising proper hand hygiene.
