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.

Physical distancing effectiveness is the reduction in the transmission of COVID-19 between an infected person and someone who has never had COVID-19, compared to the beginning of the pandemic in March 2020.

Safe socializing is ensuring you don’t become a link in a COVID-19 transmission chain that ends in a person becoming hospitalized or dying.
