The Delayed Curve

The Epidemiological curve, or “epi-curve,” wasn’t designed to satisfy the public’s desire for instant understanding about the spread of COVID-19. Infections confirmed today were contracted days or even weeks earlier. (It takes time for symptoms to present, medical help to be obtained, tests to be taken and results confirmed.) In this visual, VPAP shows how information Virginia gathered during the week ending April 5 revealed the spread of COVID-19 in early March.
