According tomedia reports, many experts believe that the “second wave” of the new coronavirus outbreak is inevitable, but a new study shows that there is a way to prevent COVID-19 infection “second wave.” To avoid a severe second wave of COVID-19 infections, people need to wear masks and maintain social distance, the study said.
Recent surges in new crown confirmed cases across the United States following the reopening, such as the influx of tourists into casinos in Las Vegas, have led to a significant increase in the number of new crown confirmed cases in the city.
Scientists at the University of Cambridge and the University of Greenwich published a study this week showing that wearing a mask can significantly reduce the risk of another wave of coronavirus infection. If enough people wear masks, the spread rate of COVID-19 will drop dramatically and remain at a manageable level, rather than overburdening the health care system.
“Our analysis supports the public’s immediate and widespread wear of masks,” said Dr Richard Stutt, one of the study’s leaders at the University of Cambridge. From reuters reporting on the study:
In the study, the researchers linked the dynamics of human-to-human transmission to models at the population level to assess the effect of different mask adoptions combined with the blocking period on disease reproduction rates, or R-values.
The R value measures the average number of people infected with an infection who transmits the disease. An R value of more than 1 will cause exponential growth.
The study found that if people wear a mask at any time in public, they are twice as effective at lowering their R value simply as they do wearing a mask only after symptoms.
In all the scenarios examined, 50 percent or more of the population routinely used masks to reduce the spread of COVID-19 to less than 1.0 R, calm future waves of disease, and impose less stringent blockades.
The findings, published in the scientific journal Proceedings ayear, are not the first to publish these findings. Several other studies have come to similar conclusions: for example, it is thought that wearing a mask in public and maintaining a social distance can have a significant impact on the spread of COVID-19.
