Practice worked best if the reference was worn before a person’s symptoms showed up, according to the authors of the paper published in the magazine BMJ Worldwide health found. In the study, the mask types worn by the participants were not described in detail.
According to a study, wearing a face mask at home could prevent the coronavirus that causes COVID-19 from spreading among family members.
Mask wear has become more common around the world since the COVID-19 pandemic began, as health officials hope it will prevent the virus from spreading. In early April, for example, the United States Disease Control Centers (CDC) updated their COVID-19 guidelines to specify that people should wear masks in public when it is difficult to maintain social distance.
According to Johns Hopkins University, more than 5.7 million COVID-19 cases have been confirmed and 356,124 people have died. Over 2.3 million people have recovered.
In the latest study, led by Yu Wang from the Beijing Center for Disease Prevention and Control in China, researchers say COVID-19 has spread mainly to families and close to the sick, accounting for 70 percent of cases in China .

To find out whether wearing a mask at home could prevent the transmission, the researchers invited all 181 people in the Chinese capital Beijing who had tested positive for the corona virus on February 21, 2020, to fill out a questionnaire. They were asked about their hygiene habits and their approach to COVID-19, e.g. B. after ventilation of the house and cleaning. After various households were excluded or refused to participate, 335 people from 124 families in which at least one person tested positive were included in the analysis.
The standard practice in Beijing meant that the sick person was hospitalized after she was diagnosed with COVID-19.
A family was defined as people who had lived with the sick person for four days before and more than 24 hours after the onset of symptoms. On average, the families had four members in the range of two to nine, and typically included children, parents, and grandparents, as is typical in China, the team said.
The team found that almost a quarter of family members were infected with 23 percent within two weeks of the sick person’s illness. However, if the sick person and their family members wore a mask at home before the person developed symptoms, it was 79 percent effective in reducing transmission.
However, there seemed to be no benefit to the sick person who wore the mask after their symptoms showed. This may be because, as previous studies have shown, viral load appears to be highest in the two days before and on the first day that symptoms appear, the team said.
“The results suggest that the use of face masks in the community is probably the most effective for severe household epidemics,” the scientists wrote.
In addition, the use of ethanol and chlorine-based household disinfectants was 77 percent effective in preventing the spread of the virus. The risk of transmission in a household was 18 times higher when family members were in close contact with the sick person every day.
Even in homes that are “crowded and small”, measures such as wearing masks, social distance and cleaning have helped to prevent this Corona virus Spread, the researchers said.
The authors admitted that their study had several limitations, including interviewing participants over the phone, and trusted that they would report their behavior accurately. They also did not collect data on the strength of the family disinfectant.
Against the background of the results, the team, which includes researchers from China, the United States and Australia, recommends families with members who are at greatest risk of catching Corona virus Wear masks at home. This includes those who have been contacted COVID-19 patients, medical personnel or those who have traveled to a high risk area.
“It [the study]provides information on the use of universal face masks and social distancing, not only in public spaces but also in the home, with members being at risk of infection. This further supports the universal use of face masks and also provides risk mitigation guidelines for families who are in quarantine or isolation with someone, and for families of health workers who may be at constant risk, ”they write.
As the following Statista chart shows, the United States is the country with the best known COVID-19 cases. This week, the death toll in this country has exceeded 100,000.
