also as Texas and Mississippi Officials Remove Statewide Mask MandateResearchers at the Centers for Disease Control and Prevention presented fresh evidence of the importance of covering the face on Friday, suggesting that people wearing masks Coronavirus and Kovid-19 were associated with fewer infections with deaths In counties across the United States.
Federal researchers also found that counties opening restaurants for on-premises dining – indoors or out – saw an increase in daily infections after about six weeks, and an increase in Kovid-19 mortality nearly two months later.
The study does not prove cause and effect, but class with the findings Other research suggests that masks prevent infection And that the indoor space aerosol promotes the spread of viruses through small respiratory particles that live in the air.
The director of the CDC, Drs. Rochelle P. “You reduce cases and deaths by wearing masks and when you eat at an in-person restaurant, you increase in cases and deaths,” Wallensky said on Friday. “And so we will advocate for policies, certainly when we are on the plateau of a high number of cases, will listen to that public health science.”
City and state officials arrive as a nationwide vineyard with increasing pressure to reopen schools and businesses amid new cases and falling rates of deaths. Officials recently Limited indoor dining allowed in New York City. On Thursday, the governor of Connecticut said the state Capacity limit will be reached Later this month on restaurants, gyms and offices. Both locations still require masks.
“The study is not surprising,” said Joseph Allen, associate professor at Harvard’s TH Chan School of Public Health and director of the university’s Healthy Buildings Program. “What is surprising is that we see some states ignoring all evidence and quickly opening up, and removing the masked mandate and having a full meal.”
Other researchers said the new study confirmed the idea that viral transmission often occurs through the air, physical disturbances may not be enough to prevent the spread in some settings, and that masks are at least partially Block airborne particles from.
President Biden’s health advisors have said in recent days that now is not the time to rest. According to a database maintained by the database, as of Thursday, the seven-day average of new cases was 62,924 days. new York Times.
While the figure is down 14 percent from two weeks ago, peaks reported last summer remain new cases. Although plagues are falling, Part of the reason for the vaccination campaign in nursing homes, It is regular for 2,000 deaths Notice will be given on the same day.
Mr biden on wednesday Rulings criticized The governors of Texas and Mississippi called the plans reflecting “Neanderthal thinking” a major mistake, to lift statewide facade mandates and reopen businesses without restrictions.
The president, who has asked Americans to wear masks during their first 100 days in office, said it was important for public officials to follow the guidance of doctors and public health leaders as the coronovirus vaccination campaign gains momentum. As of Thursday, there were about 54 million people Received At least one dose of Kovid-19 vaccine.
“It may seem tempting, in the face of all this progress, to try to get back to normalcy as if the virus is in the rearview mirror.” Andy Slavit, A White House advisor on the epidemic, said on Friday. “this.”
CDC researchers examined associations between mask mandates, indoor or outdoor restaurant meals, and coronavirus infections and deaths between March 1 and December 31 last year. The agency relied on county-level data from state government websites and measured daily percentage changes in coronavirus cases. And deaths.
The agency found that infections and deaths declined after counted mandatory mask use. The counties were allowed to open restaurants to dine on the campus and the daily transition increased about six weeks after the death toll rose two months later.
The authors of the report concluded that masked mandates were associated with statistically significant declines in coronovirus cases and mortality within 20 days of implementation. The restaurant, compounded on food indoors or outdoors, was associated with increased case and mortality after reopening in 41 days.
“State mask mandates and banning on-premises dining in restaurants help limit potential exposure to SARS-CoV-2, reducing Kovid-19’s community broadcasts,” the authors wrote.
Shortly after publishing the report, the CDC amended it, urging establishments that resume serving food to follow the agency’s guidelines to reduce broadcasting in restaurants.
Gary P., scientist and study author of the CDC’s Kovid’s response team. “The message is that if restaurants are going to open for on-premises dining, then it is important to follow the CDC guidelines,” Guy said. .
Including “all people living in the home showing signs of Kovid when they show Kovid symptoms or have tested positive or are in contact with someone who needs a mask for employees as well as those customers Is, those who are not actively eating or drinking, “Dr. Where is the cow said.
Other steps include adequate ventilation, outdoor dining options, keeping customers six feet apart, encouraging frequent hand washing, and sanitizing surfaces that are heavily touched, such as cash registers or payment terminals. , Door handles and tables.
If the ventilation is insufficient, even if the capacity of the restaurant is limited, the aerosolized virus may accumulate.
“It doesn’t really matter if it’s a restaurant, spin class, a gym, a choir practice – if you’re indoors without masks, little or no ventilation, we know it’s a high risk ,” They said. “Respiratory aerosols are made indoors. It’s so easy. It’s a real problem for restaurants.”
Lincey Mara, an expert on aerosol transmission at Virginia Tech, said Americans cannot be expected to follow all the latest sciences, and many simply rely on what is uncovered as an indicator of what is safe or not. Is closed
But indoor dining is particularly risky, she said. People usually sit in a restaurant for an hour or more and do not wear masks while eating, causing them to succumb to the virus that spreads in the air.
“Limiting capacity will help reduce the risk of transmission, but indoor eating is still a high-risk activity until more people are vaccinated,” she said.
Restaurant employees are particularly exposed. While they may wear masks, diners do not, reducing protection against viruses. Dr. Ellen said that workers spend many hours inside with every shift.
He recommended that restaurant workers wearing double-masks, surgical masks, or wearing cloth masks, such as N95, buy high-efficiency masks, usually reserved for health care workers, or KN 95 or KF 94 masks, Taking steps to convince them that they are not fake.
Dr. “Now is not the time to go down our guard and pull back on control when we are close to vaccinating a lot of people,” Allen said.
