The study found that the mandates of the masks – eating affects the spread of the virus

NEW YORK (AP) – A new national study adds strong evidence that mask mandates could slow the spread of the coronavirus, that restaurant cooking could increase և mortality.

The Centers for Disease Control and Prevention released the study on Friday.

“This is very backward,” said CDC Director Dr. Rochelle Valensky at a White House briefing on Friday. “There is a decrease in the number of deaths wearing masks, and there is a decrease in the number of deaths when you personally eat at a restaurant.”

The study was published at a time when some states are abolishing mask mandates and restaurant restrictions. Earlier this week, Texas became the largest state to lift its mask rule by joining a movement of many governors to lift COVID-19 restrictions despite health officials.

“It’s a solid job to argue that eating in person is one of the most important things you can do if you’re going to control an epidemic,” said William Hannage, a disease dynamics expert at Harvard University who was not involved in the study.

The new study is based on smaller studies by the CDC, including a study that found that people infected in 10 states in July were more likely to eat at a restaurant, and another found a masked mandate in 10 states. with hospitalizations reductions.

CDC researchers surveyed areas of the United States that are under state-mandated mask mandates, countries that allow restaurant dining, both indoors and outdoors. The study looked at data from March to December last year.

Scientists have found that the mandates of the masks are associated with a reduction in coronavirus transmission, նոր new cases over time և improvements in deaths increase.

Growths ranged from half a percentage point to almost 2 percentage points. It may seem small, but the large number of people involved means that the impact grows over time, experts say.

“Every day as that growth rate slows, the cumulative impact on deaths becomes quite large,” said Gary Guy Jr., a CDC scientist who led the study.

The reopening of the restaurant did not result in a significant increase in և deaths during the first 40 days after the restrictions were lifted. But after that, there was an increase of about 1 percentage point in the growth rate of cases, and later from 2 to 3 percentage points in the growth rate of mortality.

The delay could be due to the fact that the restaurants did not reopen immediately, and that many customers may have hesitated to dine immediately after the restrictions were lifted, Guy said.

In addition, there are always consequences when people become infected, when they get sick, and longer when they are in the hospital and die. Delayed death from eating out can also be caused by the fact that the eaters themselves cannot die, but they can become infected and then spread to patients who become ill and die.

“What happens in a restaurant does not stay in a restaurant,” he said.

CDC officials stopped saying that dinner inside should be stopped. But they said that if restaurants were to open, they should take as many preventive measures as possible, such as promoting outdoor meals, having proper ventilation in the room, masking staff, and masking customers when they were not eating or drinking.

The study had its limitations. For example, researchers have tried to make calculations that take into account other policies, such as banning or blocking mass gatherings, that could affect the number of deaths. But the authors acknowledged that they could not take into account all the possible impacts, such as the reopening of schools.

“It is always very, very difficult to break the causal ties in detail,” Hanaj said. “But when you take this collection with all the other things we know about the virus, it supports the message of wearing a mask and eating at a restaurant,” he added.
