Rate of Positive Tests in the US and States Over Time
How Much Of The Disease Are We Finding Through Tests?
This graph shows the total daily number of virus tests conducted in each state and of those tests, how many were positive each day. The trend line in blue shows the average percentage of tests that were positive over the last 7 days. The rate of positivity is an important indicator because it can provide insights into whether a community is conducting enough testing to find cases. If a community’s positivity is high, it suggests that that community may largely be testing the sickest patients and possibly missing milder or asymptomatic cases. A lower positivity may indicate that a community is including in its testing patients with milder or no symptoms. The WHO has said that in countries that have conducted extensive testing for COVID-19, should remain at 5% or lower for at least 14 days.
Federal guidelines advise that states wait until they experience a downward trajectory of documented cases within a 14-day period before proceeding to a phased opening. In the state-specific view of the graph, this two-week period is highlighted in orange if cases are trending upward, or green if they are trending down.
