Covid-19 is now the No. 3 cause of death in the US. But testing to find and isolate cases has failed


In the past three weeks, the U.S. has averaged more than 1,000 Covid-19 deaths per day.

“Covid is now the No. 3 cause of death in the U.S. – ahead of accidents, injuries, lung disease, diabetes, Alzheimer’s, and many, many other causes,” said Dr. Thomas Frieden, a former director of the Centers for Disease Control and Prevention.

Heart disease and cancer are the leading causes of death in the US, according to the CDC.

The death toll from Covid-19 is also much higher in the U.S. than in many other countries, Frieden said.

“Last week, Americans were eight times more likely to kill Covid than Europeans were,” he said.

Less testing = more infected people running

Just as more students are returning to school, health experts are worried about a disruptive trend: declining tests combined with high test-positive scores.

In other words, Covid-19 is still very widespread, but there are fewer tests to find and isolate cases.

The number of tests performed each day in the US dropped by an average of 68,000 compared to the daily rate at the end of July, according to data from the Covid Tracking Project.

Fifteen states conducted fewer tests this week compared to the previous week: Mississippi, Louisiana, North Carolina, Washington state, Rhode Island, Wisconsin, Minnesota, Colorado, New Mexico, Arizona, Utah, Nevada, Idaho, Montana and Alaska .

However, test positivity scores – the percentage of tests that are positive – are even higher than the recommended 5% in more than 30 states, according to Johns Hopkins University data.

“The test situation is not good in the United States. What we do not pick up are people who are contagious,” said Dr. William Haseltine, president and president of ACCESS Health International.

“We probably miss 8 out of 10 people who are infected. And any decrease in testing is worrying because we are not doing it right already. And if you do not choose people from an infected person, then the epidemic. This epidemic is still widespread. ”

Why do some states test less?

Medical experts say there could be several reasons.

“One of the reasons testing is declining is that deliveries are not being sent to places that can be tested. I think it’s part of a strategy to not count how many people are infected,” Haseltine said.

Sepkowitz: America follows Trump's dangerous advice to delay testing
Another reason is that people may be less motivated to be tested, knowing that it may take several days or longer to get results. And major delays can make some tests “borderless useless.”
Dr. Kent Sepkowitz said he was afraid some states might take instructions from President Donald Trump, who said “if you do more testing, you will find more cases,” which the United States “can see poorly.”
Sepkowitz notes that several states that have counted reduced cases have also had some of the highest test positivity scores – an indicator that the virus is spreading.
“Thus, even as rates fall, many states have decided to reduce their efforts to find cases,” he wrote. “As a result, by searching less, they find fewer cases and sure enough, the case numbers go down.”

Lack of minority volunteers could delay faxes

A Covid-19 vaccine could be delayed if not enough minorities volunteer
While medical experts hope a vaccine will be publicly available by 2021, researchers have encountered a problem: not enough Black and Latino volunteers have signed up for clinical trials.
Of the 350,000 people who have registered online, 10% are black as Latino, according to Dr. Jim Kublin, executive director of operations for the Covid-19 Prevention Network.

That is not nearly enough, because subjects reflect the population that is affected. Research shows that more than half of American Covid-19 cases have been between Black and Latino people.

Much of the mistrust stems from a history of medical atrocities against minorities. From 1932 to 1972, Black men were subjects in the Tuskegee syphilis study without their knowledge or permission and were not offered penicillin to treat their disease.

In the 1800s, Drs. J. Marion Sims on slaves and performed operations without their permission and without anesthesia.

And from the 1940s to the 1970s, researchers in various studies exposed hundreds of subjects – mostly Black people – to dangerous amounts of radiation.
Health officials are trying to win the trust of minority communities and are recruiting more diverse volunteers for Phase 3 coronavirus vaccine tests.

So far, phases 1 and 2 have shown that the vaccine is safe. Some volunteers experienced fever and muscle cramps, but after a day or two they felt better.

A quick, inexpensive test just got emergency service approval

There’s some good news: A new detective test could give Americans a quick way to learn if they have Covid-19 – and if they need to isolate it to help prevent it from spreading.

With major delays in Covid-19 testing, the AMA draws up guidelines on who should be prioritized
Researchers from the Yale School of Public Health conducted the SalivaDirect test, which on Saturday received authorization for emergency use from the Food and Drug Administration.

“If cheap alternatives like SalivaDirect can be implemented nationwide, we can finally get a grip on this pandemic, even before a vaccine,” said Nathan Grubaugh, a Yale assistant professor of epidemiology.

Unlike some other tests that require specialized deliveries, the SalivaDirect test does not require a specific swab as a collection device. It can also be used with reagents from multiple vendors.

“We’ve simplified the test so that it only costs a few dollars for reagent, and we expect labs to only pay about $ 10 per sample,” Grubaugh said.

Researchers said the new test could produce results in less than three hours, and the accuracy is consistent with results from traditional nasal swabbing. They said SalivaDirect tests could be made public in the coming weeks.

‘We need to pass on to our young people’

Shortly after their classes reopened, thousands of students had to stay home and quarantine to coronavirus clusters at their schools.

Health experts are urging younger Americans to take precautionary measures seriously, especially after the CDC said that Covid-19 cases among children “gradually increased” from March to July.

“Recent evidence suggests that children are likely to have the same as higher viral loads in their nasopharynx compared to adults and that children can spread the virus effectively in households and camp settings,” the CDC said.

Outbreaks have also occurred at colleges and universities.

Oklahoma State University said Sunday that at least 23 members of sorority in an off-campus house tested positive for the virus. The entire house is in quarantined isolation and “will be banned from leaving the facility,” the university said.

Universities reopening are already reporting clusters of Covid-19 cases
Less than a week after starting classes, the University of North Carolina at Chapel Hill announced its fourth cluster of coronavirus. The clusters were located at two residences, a private apartment complex serving students and the Sigma Nu fraternal.

The North Carolina Department of Health and Human Services defines a cluster as five or more cases in the neighborhood. As of Monday morning, 177 students are in isolation and 349 are in quarantine, both on and off campus. About 30,000 students attend the university.

The school has initially shifted to online learning.
