After the controversy over the feasibility of masks in the time of the emerging Corona virus, researchers have studied the effect of muzzles used in surgery on the transmission of types of coronaviruses and influenza that masks can help limit the spread of Covid-19 pandemic.

The study showed that the use of surgical masks by those infected greatly reduced the number of influenza viruses, which can be detected in droplets released during breathing and coughing.

It also reduced the number of seasonal coronaviruses, which are common causes of colds, which can be detected in the air, such as dust. However, the study did not study the effect of using these respirators on transmission of the emerging coronavirus or SARS.

The researchers said: “More research is needed to determine whether gags can specifically prevent transmission of the SARS Cove-2 virus.”

In addition, the research, which was published in the journal Nature, coincides with the pandemic of Covid-19 respiratory disease, which affected more than a million people worldwide and claimed the lives of more than 53,000 people.

Benjamin Kaoling, a professor who led the study at the World Health Organization Collaborating Center for Infectious Diseases in Hong Kong, said his findings could include the simplest cotton masks in their manufacture.
