According to an observational study published Thursday in the medical journal Thorax, homemade cloth face masks probably require two or three layers to be effective in preventing the spread of coronaviruses.

Researchers at the University of New South Wales in Australia have found that single-layer and double-layer cloth surface covers are used to reduce the spread of respiratory droplets that the infected person passes through when speaking, coughing, or sneezing. I checked the effectiveness of. The results were then compared with those of a 3-layer surgical face mask.

The researchers used LED lighting and a high-speed camera to photograph the airborne splashes created by a healthy person without respiratory infections. The video to speak was captured at 850 frames per second, while the cough and sneeze were captured at 1,000 frames per second due to the fast expulsion rate.

A three-layer surgical face mask was most effective at reducing airborne splashes, researchers found after viewing the footage. According to the researchers, a single-layer cover reduced droplet spreading, while a two-layer cover was better at reducing droplet coughing and sneezing.

“At least two layers of fabric cover are preferable to a single layer,” said study lead author Prateek Bahl of the Department of Mechanical Engineering at UNSW. “The guidelines for homemade cloth masks need to specify multiple layers.”

Indeed, the researchers said that a single-layer face cover is better than no face cover. In addition, several other factors determine the effectiveness of a cloth mask, such as the type of material, the number of layers, the placement of different layers, and the frequency of cleaning, they said.

The single layer face cover was made from a folded cotton T-shirt and tie. Two layer coating was made using sewing method Shown in Centers for Disease Control and Prevention. Researchers have used tissue paper to simulate the nasal mucosa and induce sneezing.

The study begins with the Trump administration demanding that the public adopt a face mask to curb the spread of coronaviruses. According to data compiled by Johns Hopkins University, the United States is the worst outbreak in the world with 4 million cases and at least 143,820 deaths.

President Donald Trump Responses to pandemics are also closely monitored. Over the last few weeks, Trump has downplayed the threat of the virus and linked the proliferation of new cases to more tests. However, public health officials and infectious disease experts have challenged these claims, saying that the proportion of cases tested positive in the United States, hospitalization and death remained high in some states.

Trump approved the mask for the first time this month after a few months of resistance. CDC started recommending face masks for the general public in April.

Earlier in the day, Admiral Brett Giroir, Assistant Secretary of Health at the Ministry of Health and Welfare, told reporters. 90% or more of the people required Wear a face cover to reduce the spread of the virus.

“Closed indoor bars, reduced restaurant occupancy, face coverage, and hygiene are essentially the same as shutting down the entire economy. It’s about shutting down.”
