Mississippi followed Texas (19.25%), Florida (17.47%), Alabama (17.34%) Nevada (16.35%) states with the highest five average positivity rates in the last two weeks.
The average positivity rate has been highest in one or more states in at least 8 states in the past two weeks, according to the most recent report published Sunday by Johns Hopkins University.
Washington state reported the largest buildup in its average positivity rate in the last 14 days, from 9.6 percent of 5.6 percent two weeks ago to 15.2 percent last week. Texas recorded the second-highest increase, from 6.9% from 12.4% two weeks ago to 19.3% last week, according to Johns Hopkins University.
The positivity rate calculated for each state “looks at number of cases divided by number of negative tests plus number of cases. We feel that the ideal way to calculate positivity would be number of people who test positive divided by number of people who are tested,” Johns Hopkins University noted.
“We believe this is lately the most productive way to track positivity, as some states come with successive repeated tests on the same individual, as well as unrelated antibody tests,” he added.
Knowledge of the tests reported through some states would likely come with serological tests (antibody tests) in addition to viral tests. Antibody tests are used to detect past trip infections in others who had few or no symptoms, but who are not used to encountering an active coronavirus infection.
Johns Hopkins University explained: “When states report control numbers for COVID-19 infection, they do not include serological controls or antibodies. Antibody controls are not used to diagnose an active infection with COVID-19 and do not provide data on the number of cases of COVID-19 diagnosed or whether viral controls are sufficient to detect infections occurring in all states.
“Currently, states may not distinguish all managed tests from the number of Americans that have been evaluated. This is a significant limitation on the knowledge that you must have to track evidence in the United States, and state paintings to deal with this,” he added.
In May, the World Health Organization (WHO) informed governments that the positivity rate in a given population remains at least five% or less for at least 14 days before reopening.
As of Sunday, the seven-day average of positivity rates recorded in the previous week was reported to be above five percent in 36 states and below five percent in 14 states, according to Johns Hopkins University.
