According to an upcoming study, the lockdown reduced the prevalence of COVID-19 in New York City by 70 percent.

For the study, scientists at Columbia University Mailman School of Public Health and New York City of Health and Mental Hygiene looked at how public health interventions succeed – such as closing school, staying indoors, and applying face masks – to the city in March. COVID-19 transmission rates to occur in June until “reopening”. Scientists found that these measures were highly effective in reducing coronovirus infection rates.

In fact, the success rate of New York City lockdown was higher than that seen in Wuhan, China. According to a Columbia University press release, “The new study is in line with previous modeling studies that estimated the lockdown to have reduced transmission by 58 percent in China’s Wuhan, 45 percent in Italy and 77 percent in France.”

Ohio State University Wexner Chief Quality and Patient Safety Officer Drs. “New York’s response is the closest thing we’ve seen to how other countries have reacted, and that’s why it was so effective there and in other countries,” said Ihn Gonsenhauser. The medical center tells Yahoo Life.

While stay-at-home orders had the most significant results, researchers also found that widespread use of facial masks helped reduce infection rates by up to 7 percent. The rate of cut was even higher for older adults – up to 20 percent of those 65 and required face masks in public places during the first month – who seem to be better off wearing face masks.

However, experts are not surprised by the report’s findings. “I don’t think many people in health care are going to be surprised by this discovery or even how significant the reduction is for lockdowns,” Gonsenhauser says. “We all know that it is all about connectivity. The spread of viral is about all people coming into contact with each other. ”

Since the virus spreads mainly through person-to-person contact, “when you have a lockdown, everyone stays at home and you turn off too much human contact,” the study’s lead author, Van Yang, dept. An assistant professor at epidemiology at Columbia University Mailman School of Public Health, tells Yahoo Life.

The other reason lockdown works is that they are generally mandatory. “It’s the lack of options that makes it so effective,” Gossenhasser says. “There are a lot of people who are going to choose not to do the right thing, and it doesn’t like it.”

The report also finds that wearing masks does make a difference: if the current rate of wearing masks in New York City continues, as more people spend time outdoors, “reopening by about 9 to 11 percent overall. COVID-19 may help reduce transmission, “” according to the press release. However, “if we’re enabling the entire population to wear face masks” – what older adults are doing Along the lines – “We can reduce transmission for the entire population by about 30 percent,” Yang says. “It is very important in reducing transmission.”

Yang says wearing masks should not be “political”.

“It’s for our own health,” she says. “And for the safety of our neighbors and our community. It should be the responsibility of every citizen. Everyone should participate to contribute to the best result. ”

However, there is no question that the lockdowns are effective, a senior scholar at the Johns Hopkins Center for Health Security, Drs. Amesh A. Adalja tells Yahoo Life that they are like a “blunt tool” used only because “New York City” was in crisis. ”

Experts acknowledge that lockdowns are not sustainable. “It’s a real cost on people’s lives, and you have to think long-term,” Adalja says.

Adds Yang: “We know for sure that lockdown is very effective in preventing transmission. The problem is that we cannot lockdown all the time. [The question is] How can we reopen? I fully understand the struggle of businesses [during lockdown]. But if we open up and we get an increase in infections, we not only endanger everyone’s life, but we [also] Will not be able to open business as well.

As Gönsenhauser states: “If you don’t set a fire and it keeps on smoldering, it’s going to burn again.

However, experts agree that there are many tools in the public arsenal that help fight the spread of coronaviruses without going into lockdown. Along with testing and contact tracing, they include “social disturbances, staying six feet away from people, covering a face when you can’t do social distance [and] Good hand hygiene – these are all important tools, ”said Adalja.

As Yang stated in the press release: “We need to implement them all together to effectively reduce the spread of COID-19.”
