According to a study published in the Journal of the American Medical Association (JAMA), plastic shields can protect against COVID-19 better than medical masks.
The authors of the Moving Personal Protective Equipment Into the Community study analyzed which personal protective equipment better blocks airborne virus transmission.
People can get infected with SARS-CoV-2 in ways typical of replication viruses. For example, if the virus enters the nose, eyes or mouth.
The study shows that plastic shields can capture up to 92% of viral particles, but with a recommended safe distance of two meters.
The main disadvantages of masks, according to the specialists involved in the study, are the short period of effective use.
Scientists note that the use of plastic shields will help curb the spread of COVID-19, and evaluated their effectiveness in the range of 68 to 96%.
