Lockdown reduced the spread of COVID-19 in New York by 70%, according to a forthcoming study.

For the study, scientists from Columbia University Mailman School of Public Health and the New York City Department of Health and Mental Hygiene looked at the success of public health interventions – such as school closures, stay-at-home orders, and face masks. for the face – widespread transmission rates of COVID-19 occurring in the city from March until its “reopening” in June. Scientists found that these measures were highly effective in reducing coronavirus infection rates.

In fact, the success rate of the New York City blockade was even higher than what was seen in Wuhan, China. According to the Columbia University press release, “the new study is in line with previous modeling studies which estimated the blockages reduced COVID-19 transmission by 58% in Wuhan, China, by 45% in Italy, and by 77 in France “.

“The New York response is the closest we’ve seen to how other countries have responded, which is why it has been so effective there and in other countries,” Dr. Iahn Gonsenhauser, head of patient quality and safety at Ohio State University Wexner Medical Center, he tells Yahoo Life.

While the home orders had the most significant results, the researchers also found that the widespread use of face masks helped reduce infection rates by an additional 7%. The reduction rates were even higher for older adults – up to 20% among those aged 65 and over during the first month that face masks were needed in public places – who appear to be better in public places. ‘wear masks.

However, the experts are not surprised by the report’s findings. “I don’t think too many people in the healthcare industry will be surprised by this discovery or even how significant the reduction attributed to the blockade is,” says Gonsenhauser. “We all recognize that it’s about contact. Viral spread affects people who come into contact with each other. “

Because the virus is spread primarily through in-person contact, “when you have a blockage, everyone stays at home and most human contact is cut off,” lead author of the study, Wan Yang, assistant professor in the department of epidemiology at Columbia University Mailman School of Public Health, he tells Yahoo Life.

The other reason locks work is that they are usually mandatory. “It’s this lack of options that makes it so effective,” says Gonsenhauser. “There are a lot of people who will choose not to do the right thing, and that doesn’t make it a choice.”

The report also found that wearing masks makes a difference: If current rates of wearing masks in New York City continue as more people spend time outdoors, this may help “reduce overall COVID-19 transmission by about 9-11% during reopening, “According to the press release. However, “if we were able to get the entire population to wear face masks” – more along the lines of what the elderly have done – “we would be able to reduce transmission for the entire population to around 30. % “, Says Yang. “This is very important to reduce transmission.”

Yang adds that wearing a mask shouldn’t be “political”.

“It’s for our health,” he says. “And for the protection of our neighbors and our community. It should be the responsibility of every citizen. Everyone should do their part to contribute to the best result “.

While there is no doubt that the blockers are effective, Dr. Amesh A. Adalja, a senior scholar at the Johns Hopkins Center for Health Security, tells Yahoo Life that they are like a “straightforward tool” that was only used because “New York City was in crisis.”

Experts acknowledge that the blocks are not sustainable. “This has a real cost to people’s lives and you have to think long term,” says Adalja.

Yang adds: “We know for a fact that blocking is very effective in terms of limiting transmission. The problem is, we can’t freeze all the time. [The question is] how can we safely reopen? I fully understand the struggle of businesses [during lockdown]. But if we open up and get another huge increase in cases, infections, not only are we risking everyone’s life, but we too. [also] will not be able to open business as well. “

As Gonsenhauser says: “If you don’t put out the fire and it keeps burning, it will burn again.”

However, experts agree that there are several tools in the public’s arsenal that continue to help fight the spread of the coronavirus without having to go into lockdown. Along with testing and contact tracking, they include “social distance, standing two meters away from people, wearing a face cover when you can’t get away from society [and] good hand hygiene – these are all important tools, “says Adalja.

As Yang stated in the press release: “We must implement all of these simultaneously to effectively mitigate the spread of COVID-19.”
