Surgical Masks Can Prevent Transmission Of The Coronavirus

Surgical masks can prevent transmission of the coronavirus from symptomatic individuals. In new laboratory experiments by researchers at the University of Maryland, the University of Hong Kong, and the Harvard School of Public Health.

And surgical masks significantly reduced the amount of various airborne viruses from infected patients. Conducted prior to the current COVID-19 pandemic, the study does not address the question of whether users of surgical masks protect against infection.

It suggests how infected the mask may be, which is often not a symptom in the case of SARS-CoV-2 coronaviruses, spreading diseases such as influenza, rhinoviruses, and coronaviruses.

In 2013, Drs. From Maryland. Don Milton’s co-authors and colleagues have shown that surgical masks can help limit flu transmission. However, outside of controlled settings, the effect may not be as great, said Dr. Milton.

However, the possibility that surgical masks may help take a facelift is to encourage everyone to wear them outside of their homes to go to shops or other populated places during the current COVID-19 blockade.

Overall, we say that if it hasn’t been shown to be statistically significant or effective in real-world studies, we don’t recommend it. But in the midst of an epidemic, we’re desperate. The idea is that even if it slightly reduces transmission, it’s worth the worth trying.

Previous studies have shown that SARS-CoV-2 coronaviruses and other respiratory infections spread mainly during close contact, which has been interpreted by some infectious pathologists.

Which means that the disease is only by contact and large drops It can spread, like coughing or sneezing, a message that has often been shared with the public.

What they understand is that this is just a hypothesis, said Dr. Milton. The current study suggests, by contrast, that small aerosol droplets can circulate through the air. This may mean that COVID-19 can be contracted not only by coughing, but simply.

Breathing from someone close to you may be a matter of whether you have symptoms. However, surgical masks capture many aerosolized viruses as they become depleted. The researchers recruited 246 people with suspected respiratory viral infections.

Dr. How many viruses were produced without and without a surgical mask compared to Milton’s ‘Breathable Gas II Machine II’? In 111 people infected with coronaviruses, influenza viruses, or rhinoviruses.

The mask has decreased respiratory drops to detect viruses and seasonal coronavirus influenza viruses in respiratory droplets and aerosols,” said first author Dr. Nancy Lung. , who is a researcher at the university.

In contrast, masks did not reduce rhinovirus excretion. Although this experiment occurred before the current pandemic, COVID-19 and seasonal coronaviruses are closely related and may have a similar particle size.

The ability of surgical masks to reduce spiral coronaviruses to respiratory droplets and aerosols means that such masks can help delay the spread of COVID-19 when worn by infected people,” said co-lead professor.

Prince Cowling also told the university. Dr. Milton pointed out other measures that the research found to be even more effective than masks, such as improving ventilation in public places like grocery stores or installing UV-C lights near the ceiling that cover the ceiling.

K works together with fans to extract air and destroy it… Virus and bacteriaPersonal protective equipment like the N95 mask is not our first line of defense, said Dr. Milton. They are our last desperate thing we do.
