As coronavirus instances surge throughout the nation, President Donald Trump continues responsible elevated testing regardless of mounting proof that the virus is spreading broadly all through some communities.
Originally of the U.S. outbreak, public well being specialists criticized the nation’s capability to conduct widespread diagnostic testing as far too little. The nation has ramped up testing capability to greater than a median of 478,000 exams per day in June, in contrast with a median of over 345,000 per day in Might.
“Circumstances are going up within the U.S. as a result of we’re testing way over every other nation, and ever increasing,” Trump tweeted Tuesday. “With smaller testing we might present fewer instances!”
Nonetheless, public well being specialists have repeatedly stated the information doesn’t point out that elevated testing accounts for the latest surge in every day new instances. To dispel claims that testing is responsible for the nation’s rising outbreak, epidemiologists level to a determine referred to as the positivity fee, which signifies the p.c of exams that come again constructive in a given area.
The information level is vital as a result of it signifies how broadly the virus is spreading all through the neighborhood. The World Well being Group has beforehand stated that the positivity fee for a rustic ought to stay secure at about 5% for 14 days earlier than a rustic eases restrictions.
All through June to date, the U.S. positivity fee has hovered round 5%, in accordance with information compiled by Johns Hopkins College, although the seven-day common has ticked up in latest days. Some epidemiologists have famous that the truth that the nationwide postivity fee has but to drop regardless of elevated testing of the inhabitants might point out that the virus is spreading.
When damaged down by states, the U.S. paints a extra worrying image. Nineteen states presently have a positivity fee above 5% over the previous seven days, in accordance with Johns Hopkins information, and that features Arizona, which studies that 21.15% of all exams are coming again constructive, and Florida with a positivity fee of 12.22%.
“That states are discovering extra instances relative to the quantity of exams they’re conducting offers the strongest rebuttal to the administration’s assertion that case numbers are rising as a result of we’re getting higher at discovering instances via elevated testing,” Jennifer Nuzzo, lead epidemiologist of Johns Hopkins College’s Covid-19 Testing Insights Initiative, wrote in an op-ed for The Washington Publish. “They inform us the alternative — that every of those states must do much more testing to search out infections — adopted by extra rigorous contact tracing and isolation.”
Latest spikes in some states equivalent to Florida have prompted state officers to acknowledge that the rise in new instances is just not solely attributable to extra testing.
“Even with the testing rising or being flat, the variety of individuals testing constructive is accelerating sooner than that,” Florida Gov. Ron DeSantis, a Republican, instructed reporters final week. “You understand that is proof that there is transmission inside these communities.”
Most of those that take a look at constructive are actually younger individuals who “aren’t sick,” Trump instructed reporters later Tuesday. He added that the U.S., which has the most important coronavirus outbreak on this planet, has performed by much more exams than every other nation.

“By having extra instances, it sounds unhealthy. However truly what it’s, is we’re discovering individuals,” he stated. “However simply bear in mind, the rationale now we have extra instances than different nations is that our testing is a lot.”
A better share of the individuals who take a look at constructive for the coronavirus are in reality youthful, however Dr. Anthony Fauci, the nation’s high infectious illness skilled, instructed Axios on Monday that extra younger individuals testing constructive might nonetheless be worrisome.
“They get contaminated first, then they arrive house, after which they infect the older individuals. The older individuals get the issues, after which they go to the hospitals,” Fauci stated. “The demise fee at all times lags a number of weeks behind the an infection fee.”
Trump drew the ire of epidemiologists and a few politicians on Saturday when he instructed a crowd at his marketing campaign rally in Tulsa, Oklahoma, that he had instructed officers to “gradual the testing down, please” as a result of the U.S. was figuring out too many new instances. Administration officers stated the remark was made in jest and that the president has by no means directed officers to gradual testing.
Trump’s testing remarks come as states like Arizona, Texas, Florida and others significantly throughout the American South and West have ballooning outbreaks underway, former Meals and Drug Administration commissioner Dr. Scott Gottlieb instructed CNBC on Monday. Gottlieb added that extra extreme interventions is perhaps crucial quickly to cease pervasive unfold in some components of these states.
“They’re having main outbreaks underway. There is not any query about it,” he stated. “They is perhaps previous the purpose that they’ll management this simply with easy interventions like attempting to get extra individuals to put on masks and other people being aware of their social interactions.”
