Protests led to spike in coronavirus infection - report
2020-09-23
[JPost] - There was a spike in coronavirus cases in at least eight cities following the George Floyd protests, a report published last month by three American researchers has found.

"Relationship of George Floyd protests to increases in COVID-19 cases using event study methodology," was released in the Journal of Public Health and showed that Atlanta, Houston, Jacksonville, Miami, New Orleans, Orlando, Phoenix and Seattle had positive abnormal returns in the three weeks after the first day of protests.

...These US scientists used "event study methodology" to determine the abnormal growth rate that can directly be attributed to the George Floyd protests, taking an estimation period of 30 days — the days after the stay-at-home order was rescinded or expired.

Researchers looked at two parameters: the estimated period for infection growth rate and the five-day abnormal infection growth rate.

Data for each parameter were readily available on the Google search engine by entering the name of the city and the parameters studied, they said. All of the cities had reopened for at least 30 days before the protests so as to account for an increase in infections due to reopening. Also, each had documented protests in the tens of thousands.

"Comparing the actual growth rate of infections to the expected growth rate that was comprised of the 30-day estimation period that happened after there were no stay-at-home order in place, it was found that Atlanta, Miami, Orlando, Jacksonville, Phoenix and Houston have significant abnormal returns, whereas Seattle and New Orleans have positive but insignificant returns," the researchers wrote.

Seattle and New Orleans were two cities in the data set that had previously been designated as hotspots.

"These cities may have benefited from some degree of herd immunity or social awareness of the serious consequences from this viral infection," the report said.
And since we know that there is no herd immunity (unless one is a Swedish Chief)

It must be the social awareness

#4  No herd immunity, and no successful vaccine for any known coronavirus. Fun.
