According to researchers at the UCLA Fielding School of Public Research, the implementation of a nationwide mandate with complementary public health measures could reduce the spread of complementary gyroviruses, which could basically expand to zero and a potential $ 1 trillion on US GDP. have an impact on.
The team’s research “makes it clear that as vaccines develop and new versions, such as B.1.7.7, are being discovered, the power to protect ourselves remains in our hands, as individuals.” Co-author Anne Rimoin, A UCLA Fielding School Professor of Epidemiology.
“Wearing a mask is the simplest, most effective and cheapest way to heal – and this has been proven by the history of epidemiology in the last century, going back to the 1918-19 influenza epidemic and even earlier, ‘ ‘ he said.
“Two things are needed to reduce the spread of the disease: limiting exposure to infected individuals through physical disturbances and other measures, and reducing the likelihood of transmission per contact,” co-author Christina Ramirez, Biostatistics A Fielding School Professor of. ‘ Wearing that mask changes per contact by reducing the transmission of infected respiratory particles in laboratory and clinical contexts. ‘
The findings – in the January edition of Proceedings of the National Academy of Sciences, a peer-reviewed journal – were the work of an international team of 19 specialists from UCLA and more than a dozen other universities and research centers, including Oxford University, University of Cape Town, Peking University, Massachusetts Institute of Technology and University of San Francisco.
Three more cases of COVID-19 version have been San Diego County. Annette Areola reports 1 January 2021.
R0, pronounced “R naught,” is a mathematical term that indicates how contagious the infectious disease is. It is also known as reproductive number. As an infection spreads to newcomers, it reinvents itself. : Generates. Reducing fertility to zero. The authors said the US could add $ 1 trillion to GDP.
“When used in conjunction with extensive testing, contact, anyone can be infected, wash hands and suffer physical disturbances, face masks are an invaluable tool to reduce community transmission, “‘Rimoin said.’ ‘Through all these measures. Their effect on R0 has the potential to reduce the number of infections. As governments exit the lockdown, it is important to keep the transmission low to preserve the capacity of health care until vaccines can be developed and widely provided. ”
To come to its conclusion, the team investigated a wide range of new and existing studies and research, including the return to the 1910 outbreak of plague in northeast China. Nevertheless, according to the researchers, scientists fighting the plague believed that cloth masks “ are a major means of personal protection. ”
There is also substantial evidence from the current epidemic, the study’s author is co-author Jeremy Howard, a research scientist at the University of San Francisco.
“By the end of June 2020, approximately 90% of the global population lived in areas that had almost universal mask use, or laws requiring mask use in certain public places, and community mask use by nearly all major public health bodies Was recommended, ” Howard said. ” This is a revolutionary change from the early days of the epidemic, when masks were recommended or used. ”
Researchers came to various conclusions, including:
- Face masks were 79% effective at preventing transmission if they were used by all members of the household before symptoms occurred.
- The use of masks was strongly protective, with a 70% risk reduction for those who always wore masks while going out.
- In countries that did not have a mask mandate, transmission was 7.5 times higher.
- The difference between US states with a mask mandate and those without it was found that the daily growth rate was 2 percentage points lower in states with a mask mandate, estimating that the mandate had increased to 230,00 to 450,000 COVID-19 cases as of May 22. Was stopped
- If a nationwide mask mandate was enacted, facial masks would have major reductions in infections and mortality, with the potential impact of US masks on GDP of $ 1 trillion.
- The marginal benefit per masks is $ 3,000 to $ 6,000.
