CORONAVIRUS UPDATES


The United States 
reported nearly 1,500 coronavirus deaths on Wednesday, the highest number of covid-19 fatalities in one day since mid-May. 

The country has now seen its seven-day average of newly reported deaths remain above 1,000 for 17 consecutive days. 

The Labor Department announced Thursday that about 960,000 workers filed for unemployment insurance last week. 

This is the first time that initial claims dipped below 1 million since March, but it’s also still more than the pre-pandemic record of 695,000, which had been set during the 1982 recession. All told, more than 28 million people are currently receiving some form of unemployment benefits.

The F.D.A. gives emergency approval for a new spit test as U.S. testing stalls.

With the United States facing an alarming drop in coronavirus testing that threatens to undermine national monitoring efforts, the Food and Drug Administration granted emergency authorization for a new saliva-based test to detect the virus.

The new test, SalivaDirect, was developed by researchers at Yale University with some of the funding coming from the N.B.A. and the National Basketball Players Association, the university announced on Saturday in a news release. The method, it said, was being further validated through testing of asymptomatic N.B.A. players and staff members.

SalivaDirect is not the first test of its kind to secure the F.D.A.’s backing — a lab affiliated with Rutgers University received emergency authorization in May for a similar test.

Public health officials have argued for months that to get a handle on the pandemic, the United States still needs to increase overall testing, perhaps up to four million people daily, including many who are asymptomatic. But reported daily tests have trended downward for much of August and testing shortages have remained pervasive in many states.

According to the release, the researchers said they developed the test with affordability in mind, looking for ways to cut costs such as by eliminating the need for expensive collection tubes. They said they hoped labs could administer the test for around $10 per sample, contributing another test that could help combat the recent testing slowdown.

People who recovered do not need to be tested again for three months, CDC says

In recently updated guidance, the Centers for Disease Control and Prevention advises that people who have recovered from the coronavirus do not need to quarantine or seek testing for three months after they have recuperated.

The new recommendation, last updated Aug. 3, cautions that those who were previously infected should still socially distance and wear masks but says they don’t need to quarantine or be tested if they “have been in close contact” with someone who tests positive, unless they develop symptoms.

Older Children and the Coronavirus: A New report questions an earlier finding regarding transmission by older children.




A study by researchers in South Korea last month suggested that children between the ages of 10 and 19 spread the coronavirus more frequently than adults — a widely reported finding that influenced the debate about the risks of reopening schools.

But additional data from the research team now calls that conclusion into question; it’s not clear who was infecting whom. The incident underscores the need to consider the preponderance of evidence, rather than any single study, when making decisions about children’s health or education, scientists said.

Some of the household members who appeared in the initial report to have been infected by older children in fact were exposed to the virus at the same time as the children. All of them may have been infected by contacts they shared.

The disclosure does not negate the overall message of that study, experts said: Children under age 10 do not spread the virus as much as adults do, and the ability to transmit seems to increase with age.

“The most important point of the paper is that it clarifies the care with which we need to interpret individual studies, particularly of transmission of a virus where we know the dynamics are complex,” said Dr. Alasdair Munro, clinical research fellow in pediatric infectious diseases at University Hospital Southampton in Britain.

The earlier study was not intended to demonstrate transmission from children to adults, only to describe contact tracing efforts in South Korea, said Dr. Young June Choe, assistant professor of social and preventive medicine at Hallym University College of Medicine and an author of both studies.
