Neither surgical masks nor cotton masks can contain the spread of the new SARS-CoV-2 coronavirus if people infected with it cough. A new study published in the Annals of Internal Medicine showed this.
Medical masks are a common way to prevent infections that are transmitted by airborne droplets. Evidence for their effectiveness in the new coronavirus infection continues to grow. Scientists have recently shown that medical masks do not allow the passage of coronaviruses and influenza viruses, which are in the air exhaled by infected people.
Currently, most medical organizations recommend the use of masks for medical professionals and those who care for the sick. The US Centers for Disease Control and Prevention recommends that everyone wear cotton or homemade masks in public.
Scientists from Ulsan University College of Medicine in Seoul included four COVID-19 patients in their study. Each of them was asked to cough into a Petri dish five times without a mask, through a surgical mask, and through a cotton mask.
The authors of the study examined the inner and outer surfaces of the masks for viruses. They found the new coronavirus SARS COV-2 in every case. Scientists concluded that wearing masks may not be effective in preventing COVID-19.
