The United States faced a bottleneck in the coronavirus check this month as a strong call for late results. In July and early August, the nation’s largest diagnostic companies, LabCorp and Quest, took a full week to review the results.
By the time other people found that they had tested positive, they had enough time to transmit the virus to others.
This led to more selective fitness services with the other people they were testing. The result: the weekly average tests are now 13% less than at the end of July, according to the knowledge of the COVID Monitoring Project.
The United States conducted an average of 708,000 tests in the following week, compared to 818,000 at the end of July. Some states have noticed even more dramatic drops: the weekly average of coronavirus tests administered in Texas has fallen by 45% over the following month. Arizona fell 36 percent and Florida by 27%.
It’s in the opposite direction where the evidence goes, experts say.
“One of the biggest obstacles to participation is that we don’t have a verification strategy and others don’t know their status,” said Dr. Amesh Adalja, principal investigator at Johns Hopkins University’s Center for Health Safety. Business fellow. “When you look at the countries they have controlled to involve [the virus], they have done nothing extraordinary. They searched, discovered and isolated.”
LabCorp and Quest claim to have reduced response times to two or 3 days. And on average, new instances in the United States have fallen by 18% in the last two weeks.
“The minimum number of infections we’re seeing is real,” the admiral said. Brett Giroir, undersecretary of fitness at the Department of Health and Human Services, a press call Thursday.
But for some public fitness experts, the decrease may be partly the result of a decrease in testing. Proof of this is an increasing percentage of positive coronavirus tests in some states. Although the national percentage of positive testing has remained relatively solid over the following month, the percentage of positive testing in Texas has doubled in the last two weeks, from about 12% to 24%.
“When you see the percentage of positivity increase, it usually means that not all instances are captured through this system,” Adalja said in June. “All new instances are anything that is already on the radar of public fitness officials, and this is probably not the case where the percentage of positivity increases.”
The World Health Organization recommends that governments see a positivity rate of 5% or less for at least 14 days, or block the death of an epidemic. Currently, 35 U.S. states They do not comply with this directive. And thirteen states, in addition to Arizona, Florida, and Texas, have positivity rates of more than 10%.
“Considering it as a nation, it doesn’t really give you an intelligent picture of this epidemic, because it’s actually heterogeneous and regional,” Adalja said. “There are sales options like Pennsylvania and New York that decrease the percentage of positivity, while others report it.”
Data in California may also be biased, as 250,000 to 300,000 physical fitness records may have been delayed since July 25 due to a technical challenge in the state knowledge reporting system. Most physical fitness records were coronavirus tests, however, California Secretary of Health and Human Services Mark Ghaly said Friday that he was still convinced that daily instances in California had declined.
The United States evaluates more people according to human capital than any other country: about 204 tests consistent with 100,000 other people. But this also accounts for a quarter of coronavirus cases worldwide.
“Part of the explanation of why we have a massive call for [evidence] in the U.S. It’s just that we have mass epidemics,” Dr. Carolyn Cannuscio, a social epidemiologist who runs the tact curriculum at the University of Pennsylvania, told Business Insider. . Training
Slow or inadequate testing makes it difficult to identify new cases in time to prevent an epidemic from spreading, he added.
“We have a flawed verification system, and this leaves us lost in the location of the touches because other people are waiting so long to get their verification effects that we missed a critical era to advise those other people to stay at home and avoid infecting others.” Cannuscio told me. “We also missed a critical era to identify all the other people they might have been in contact with in their infectious age.”
Ideally, Adalja, the United States said, would come to a position where everyone would have to take a test.
“The next step is to make sure there are enough incentives to fund a testing program that is robust, that allows each and every American to know their prestige very temporarily with house testing,” he said. “It allows you to move forward, because one component of the challenge we’ve had from the beginning is the inability to know who’s inflamed and who’s not.”
