lockdowns worldwide are working

OAKLAND, California (Reuters) - Alphabet
Inc's Google has published charts showing how the coronavirus has
brought hard-hit Italy to a standstill, led to runs on grocery stores
around the world and prompted a stark drop in going-out between Mardi
Gras and St. Patrick's Day.
The analysis of location data from billions of Google users' phones is
the largest public dataset available to help health authorities assess
if people are abiding with shelter-in-place and similar orders issued
across the world to rein in the virus.
The company released reports for 131 countries with charts that compare
traffic from Feb. 16 to March 29 to retail and recreational venues,
train and bus stations, grocery stores and workplaces with a five-week
period earlier this year.
Google said it published the reports to avoid any confusion about what
it was providing to authorities, given the global debate that has
emerged about balancing privacy-invasive location tracking with the need
to prevent further outbreaks.
The data often correlated with the severity of outbreaks and the
harshness and breadth of orders imposed by governments.
Italy and Spain, two of the hardest-hit countries, both saw visits to
retail and recreation locations such as restaurants and movie theaters
plunge 94%. The United Kingdom, France and Philippines had declines of
more than 80% while India, which went into a sudden 21-day lockdown on
March 25, was also notable at 77%.
In the United States, where state responses have varied greatly, and in
Australia, where good weather initially prompted many people to go the
beach before social distancing measures were ratcheted up, the drops
were less steep at under 50%.
In contrast, in Japan and Sweden, where authorities have not imposed
harsh restrictions, visits to retail and recreation sites fell by
roughly only a quarter. While in South Korea, which has successfully
contained a large outbreak through aggressive testing and contact
tracing, the decline was just 19%.
The data also underscore some challenges authorities have faced in
keeping people apart. Grocery store visits surged in Singapore, the
United Kingdom and elsewhere as travel restrictions were set to go into
place. Visits to parks spiked in March in some San Francisco Bay Area
counties under lockdown in California, forcing them to later put the
sites off limits.
The data also underscores how the mood of people around the world has
shifted. In New Orleans, during its annual Mardi Gras celebrations
Feb.16-25, which has with hindsight been criticized for helping spread
the virus, there were off-the-chart increases in traffic to transit
stations, parks and businesses.
But three weeks later in Dublin, heart of St. Patrick's holiday
celebrations, traffic was down at retail and recreational venues as the
country ordered big events canceled.

Within countries, there were wide gaps in behavior by region. California, which
was the first in the U.S. with a statewide lockdown, cut visits to retail and
recreation locations by half. In New York state, the slide in such visits was
gradual as officials waited to impose strict curbs but they eventually fell 62%.
By contrast, Arkansas, one of the few states without a sweeping lockdown, had
the smallest decline at 29%.
The coronavirus has infected more than 1 million people globally, and COVID-19,
the respiratory illness it causes, has killed 52,000, according to a Reuters
tally.
There were no reports for China and Iran, where Google services are blocked.
BALANCING PRIVACY
Data in Google's reports come from users who enabled Google's "Location History"
feature on their devices. The company said it adopted technical measures to
ensure that no individual could be identified through the new reports.
"These reports have been developed to be helpful while adhering to our stringent
privacy protocols and policies," Dr. Karen DeSalvo, chief health officer for
Google Health and Jen Fitzpatrick, senior vice president for Google Geo, wrote
in a blog post.
China, Singapore, South Korea and other countries have asked residents to use
apps and other technology to track their compliance with quarantines, but
privacy activists argue such measures can compromise individual liberties.
Infectious disease specialists have said analyzing travel across groups by age,
income and other demographics could help shape public service announcements.
Google, which infers demographics from users' internet use as well as some data
given when signing up to Google services, said it was not reporting demographic
information. The company said, though, it was open to including additional
information and countries in follow-up reports.
Google said consultations with officials in the U.S. and the World Health
Organization helped inform the data shared.
The company declined to comment on whether it has received any legal requests to
share more detailed data to help with efforts to tackle the pandemic.
Facebook Inc, which like Google has billions of users, has shared location data
with non-governmental researchers that are producing similar reports for
authorities in several countries. But the social media giant has not published
any findings.
