A new study
has confirmed the efficacy of wide-scale shutdowns and restrictive social
distancing measures to contain the outbreak of the novel coronavirus that leads
to COVID-19.
The study,
published in the journal Nature, found that government-ordered shutdowns of
industry and schools stopped 530 million new COVID-19 cases in just six
countries: China, South Korea, Italy, Iran, France and the U.S.
The
staggering numbers of cases that would have been experienced and further
overwhelmed the health care system include 60 million in the U.S. and 285
million in China, according to the study.
In addition
to the 340 million cases the U.S. and China avoided, the study estimated that
without restrictive policies in place from January through April, there would
be:
To reach
the estimate, the researchers used a well-established economic technique that
is commonly used to measure the effect of events on economic growth. "This
technique aims to measure the total magnitude of the effect of changes in
policy, without requiring explicit prior information about fundamental epidemiological
parameters or mechanisms, many of which remain uncertain in the current
pandemic," the study reads. Previous work looking at influenza has shown
that this technique is accurate for estimating infection rates, according to
the study.
While the study
period ended on April 6, the orders to shelter-in-place long after April 6 have
likely led to many millions more infections avoided, the study's lead author,
Solomon Hsiang, a professor and director of the Global Policy Laboratory at the
University of California, Berkeley, said in a press release on Monday, as CNN
reported.
"The
last several months have been extraordinarily difficult, but through our
individual sacrifices, people everywhere have each contributed to one of
humanity's greatest collective achievements," Hsiang said in the press
release, according to CNN.
"I
don't think any human endeavor has ever saved so many lives in such a short
period of time. There have been huge personal costs to staying home and
canceling events, but the data show that each day made a profound difference.
By using science and cooperating, we changed the course of history."
On Monday,
Nature also published another study from epidemiologists at Imperial College
London. As The Washington Post reported, that study estimated that the
shutdowns saved about 3.1 million lives in 11 European countries, including
500,000 in the United Kingdom, and dropped infection rates by an average of 82
percent, which was enough to drive the contagion well below epidemic levels.
The two
studies provide fresh evidence that the severe economic sacrifice the COVID-19
shutdowns caused were worth it to save many millions of lives. However, Samir
Bhatt, the lead author the latter study, cautioned that the virus has only
infected three to four percent of the people in the countries they studied.
That makes most of the population highly susceptible to the contagion, as The
Washington Post reported.
"This
is just the beginning of the epidemic: we're very far from herd immunity,"
Bhatt said Monday in an email, as The Washington Post reported.
"The
risk of a second wave happening if all interventions and precautions are
abandoned is very real."
