Scientists at Cambridge University in England have responded to what the World Health Organization has said that face masks may provide a false sense of safety to those who wear them during the time of the outbreak of the Coronavirus.

And the World Health Organization warned last April that face masks may provide a false sense of safety and may make people think they do not need to wash their hands as much or adhere to other disease control measures.

But Cambridge scientists, according to 22 studies, have stressed the importance of the muzzle in protecting against corona, and it encourages people to adhere to other preventive measures such as hand washing, according to the British newspaper “Daily Mail”.

Scientists have found, more than that, where they found in studies that the group of people who wore face masks were more eager to wash their hands than those who did not.

According to Britain’s Ministry of Health, adherence to protective measures after wearing a muzzle is strongly encouraged in other enclosed spaces where citizens are not required by law to wear a face shield.

Some experts believe that wearing a face mask will make people think that you should never have to worry about coronavirus infection.

Early in the outbreak of the epidemic, the World Health Organization warned that masks can create a false sense of safety, and could lead to neglect of other basic measures such as, hand hygiene practices.

The organization described this behavior as “risk compensation” or “ethical licensing,” meaning for example, a cyclist might wear a helmet but only so that he could ride a bike more quickly and more dangerous, rather than provide protection for himself and walk at the usual speed.

Professor Dam Teresa Marto and her colleagues at the University of Cambridge wanted to see if the same was true for people dealing with coronavirus infection while wearing a face mask.

BMJ Analysis revealed, according to 22 studies, the value of the effect of wearing a face mask on protection from infection of SK, and respiratory system in general.

Among the six studies that also looked at whether people were still washing their hands, they found that wearing masks did not reduce interest in hand-washing or sterilizing hands.

In two other studies, people reported washing their hands more when wearing a face mask.

All studies used self-reports, which are not the most reliable measure, and none were specifically designed to consider risk compensation.

The researchers found three studies, none of which were reviewed, which evaluated the effect of mask wearing on the behavior of others around them, all showing that people have moved away from those who wear a mask, which would theoretically be a step to protect them from HIV infection.

According to the study, the idea of ​​offsetting risks used as an argument to downplay the importance of wearing face masks is unfounded.

Professor Marto and her colleagues at Cambridge stressed: “Wearing a face mask can cause the opposite, and lead people to follow other associated behaviors, such as washing hands, because it acts as a signal to remind people of the risk of coronavirus.”

The team supported their theories that risk compensation does not exist by looking at other health factors, and finding weak evidence, for example, no HPV vaccination, a group of sexually transmitted viruses, that leads to more sexual activity Danger.

The researchers concluded: “Evidence confirms that wearing a face mask reduces the prevalence of SARS-CoV-2, and that the limited evidence available does not support concerns that its use negatively affects hand hygiene.”
