U.S. COVID-19 Cases Could Have Been 35 Times Higher Without These Measures

COVID-19 cases in the Commonwealth could have reached a staggering 45,000 by April 25 without any state-imposed measures, suggested new study released by the Institute for the Study of Free Enterprise (ISFE) at the University of Kentucky. For comparison, the current total of confirmed COVID-19 cases was fewer than 4,000.

On Thursday, a new report titled, “Strong Social Distancing Measures in the United States Reduced the COVID-19 Growth Rate” was published in Health Affairs.

Coronavirus
Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

‘The combination of measures reduced the growth rate of confirmed COVID-19 cases by an amount that grew over time — reaching 9 percentage points after 16 days.’

The study evaluates the impact of four measures taken by state and local governments to slow the spread of COVID-19 across U.S. counties from March 1-April 27 — bans on large social gatherings, public school closures, the shuttering of entertainment-related businesses and shelter-in-place orders.

The authors found the closing of entertainment businesses — such as restaurants, movie theaters and gyms — and shelter-in-place orders — such as Gov. Andy Beshear’s “Healthy at Home” initiative — resulted in a dramatic reduction in COVID-19 cases.

The results imply that by April 27, the number of cases would have been 35 times higher without any of the measures — suggesting the U.S. would have reported 35 million (rather than 1 million) COVID-19 cases.

Malaria Drug and Antibiotic to Treat COVID-19
NIH has begun clinical trials of malaria drug hydroxychloroquine and antibiotic azithromycin to treat COVID-19.

“The numbers are eye-popping but illustrate the enormous power of exponential growth,” Yelowitz said.

However, the study determined the other two measures — bans on large gatherings and school closures — had a less significant impact.

Interferon-α2b Treatment Helps Speed Up COVID-19 Patients Recovery Process
In a cohort of COVID-19 patients, treatment with IFN-α2b was shown for the first time to improve virus clearance and decrease levels of inflammatory markers.

“There are many potential reasons and our arguments for non-findings are speculative, although we think it could be the case that those measures simply displace social interactions rather than reducing such interactions,” Yelowitz explained. “For example, if parents congregate in parks when schools close, it’s possible that coronavirus is spread approximately the same.”

“Most large events — like March Madness — were already being canceled anyway prior to any official prohibitions, which may have made these prohibitions redundant,” Courtemanche added. In conclusion, the authors believe the report sheds light on the current re-opening.

New Thermal Camera Detects Social Distancing Violations
An India technology company has developed a new thermal camera that detects social distancing violations.

“Our results suggest that light measures don’t work, and strong measures do, but they don’t really say anything about intermediate measures — like opening restaurants at reduced capacity, or allowing socialization with masks,” Courtemanche said. “Since we don’t know what each intermediate step towards reopening will do, it makes sense to go one step at a time and look carefully for signs that the rate of spread is picking back up.”

“My main policy recommendation would be to strongly encourage states to watch some of the early openers to see what happens,” Yelowitz added. “Given exponential growth, the rise in cases often looks unimpressive until right before things explode.”
