In the Atlantis TB data, the number 264 on June 30, 2003 represents which measure?

Explanation:
Point prevalence is the number of people who have the disease at a specific date. The figure 264 on June 30, 2003 in the Atlantis TB data is a snapshot of everyone currently living with TB on that day, regardless of when they were diagnosed. It is not counting new cases that appeared during a window (incidence), nor is it the probability of developing TB over a period (cumulative incidence). It also isn’t a tally of deaths (mortality count). So this number represents the point prevalence—the count of existing TB cases on that single date.
