Masks could cut Covid-19 deaths in US by 130,000: Study

PARIS, Oct 24: Even if state-level governments in the United States reimpose limited social distancing measures to halt the spread of Covid-19, the death toll could more than double by the end of February 2021 to 511,000, according to projections released Friday.
Near-universal mask wearing over the coming months could reduce that grim tally by nearly 130,000, researchers from the Covid-19 forecasting team at the Institute for Health Metrics and Evaluation (IHME) found.
Even if mask compliance was only 85 percent, the number of lives saved compared to that baseline would still top 95,000, they reported in the peer-reviewed journal Nature Medicine.
"There is now growing evidence that face masks can considerably reduce the transmission of respiratory viruses like SARS-CoV-2, thereby limiting the spread of COVID-19," the authors noted.
The US national average of self-reported mask use was nearly 50 percent as of September -- despite mixed messages from some politicians on their efficacy.
Donald Trump has shunned mask use in public, and has mocked his rival for the White House, Joe Biden, for his consistent wearing of them.
Few of Trump's followers cover their faces at his campaign rallies, which resumed after the president recovered from a bout with the virus earlier this month.  
Since the first confirmed case on US soil of Covid-19 in January 2020, the virus has infected some 8.4 million people across the nation and claimed more than 223,000 lives.
In mid-July, IHME modellers accurately predicted 224,000 deaths by November 1.
Today, a second -- and in some locations third -- wave of infection is rising as winter sets in, with the total number of new cases in the US topping 75,000 on October 22, nearly double the daily increase from a month earlier. 
In the absence of a vaccine and with few options for treatment, non-pharmaceutical measures such as mask wearing, social distancing, self-isolation, and contact tracing are by default the most effective tools available to curb the disease's spread. Most experts agree that, at best, an effective vaccine in not likely to be approved and available until well into next year.
To map what the near-term future might hold, IHME epidemiologists and modellers designed three possible scenarios for the United States, extending out to the end of February.   -AFP
