The Coronavirus Resource Center at Johns Hopkins charts positivity rates for each of the 50 states, with a line drawn at 5 percent. The World Health Organization advised governments that, before reopening, rates of positivity in testing — that is, out of all tests conducted, how many came back positive for COVID-19 — should remain at 5 percent or lower for at least 14 days.
