The largest review of studies on transmission of coronavirus infection confirmed that maintaining a distance of at least a meter between people, applying masks, and protecting eyes is the best way to reduce the risk of infection with the Coronavirus.
In a review of evidence compiled from 172 studies in 16 countries, researchers concluded that frequent hand washing and hygiene are also critical factors, although all of these measures combined do not provide full protection. According to "Reuters,"
said Holger Schonman, of McMaster University in Canada, who co-led the review: "Our findings are the first to collect all direct information about COFED-19, acute respiratory infection (SARS), and the Middle East respiratory syndrome (MERS)." ), And provides the best evidence currently available on optimizing these simple and common interventions to help flatten the injury curve. "
Current evidence suggests that the most common methods of spreading Covid-19 are through droplet droplets, especially when people cough and the infection is transmitted by droplets entering the eyes, nose, or mouth, either directly or through contaminated surfaces.
Researchers pointed out that although the results are comprehensive, there are some shortcomings regarding the current pandemic, because most of the evidence comes from studies on SARS and Mears.
The researchers found that social distance of at least one meter reduces the risk of Covid-19 transmission and that the two-meter distance can be more effective. They added that the masks and means of covering the eyes may enhance prevention, although the evidence for this is less clear.
Derek Chow, associate professor at McMaster University, who took part in the review, said people should understand that applying a muzzle is not a substitute for social spacing, eye protection, or basic measures like hand hygiene.
