There are many precautions we take every day to try to prevent the spread of COVID. For almost a year, we have been diligently washing our hands, wearing face masks in public and trying to keep six feet between us and anyone other than our home. But on a larger scale, different countries have taken different approaches to mitigating the virus, and even in the United States, precautions vary from state to state. Total shutdowns, company closings and mask mandates are just a few of the protocols implemented around the world to try to get the virus under control. Since we had never dealt with anything like COVID in our lives, there were some assumptions about the best way to keep people safe. Now, a recent Stanford University study found that two measures may not prevent the spread of COVID as much as we thought.

For the study, which was published in the Wiley Online Library on January 5, the researchers examined the growth of COVID cases in 10 countries to determine how beneficial various precautionary measures proved to be, looking specifically at more restrictive measures such as locks and closures. companies.
The researchers compared the COVID cases in England, France, Germany, Iran, Italy, the Netherlands, Spain and the USA – all of which instituted mandatory stay requests and closing deals – with South Korea and Sweden, which implemented only voluntary personal precautions.

After comparing countries with more restrictive measures with those with less restrictive measures, it was clear to researchers that there is “no clear and significant beneficial effect of [more restrictive measures] in the growth of cases in any country. “
Their findings suggest that mandatory blocking does not significantly stop dissemination any more than personal measures like social distance and wearing masks. “We do not question the role of all public health interventions, or of coordinated communications about the epidemic, but we have not found an additional benefit from requests to stay at home and close deals,” the authors concluded.

Sweden’s approach included “social detachment guidelines, discouraging international and domestic travel and banning large meetings”, while South Korea “relied heavily on testing, contact tracking and isolation of infected cases and close contacts”, according to Stanford Research. Even without more restrictive measures, both Sweden and South Korea had some of the lowest reported COVID cases in much of the pandemic.
As a result, the researchers concluded that “similar reductions in case growth can be achieved with less restrictive interventions” similar to those implemented by these two countries.

A study published in the journal Indoor Air in October, 318 outbreaks were observed in China, in which three or more cases were identified. The researchers divided the outbreaks into six categories: homes, transportation, food, entertainment, shopping and more – and found that people were 19 times more likely to catch the virus at home. Likewise, a survey by the University of North Carolina at Chapel Hill determined that his home is the most common location for transmitting COVID-19.
This is probably why the Stanford researchers noted that “it is possible that orders to stay at home could facilitate transmission if they increase person-to-person contact where transmission is efficient, such as closed spaces.” They cited a November study published in the journal Science who identified an increase in transmissions and cases during an order to stay at home in Hunan, China, due to intra-household transmission.
