(ORDO NEWS) — Laura Kwong, a specialist from the United States, spoke about how effective masks actually are in the fight against coronavirus. Her story was published in the scientific journal The Conversation.

In the past year and a half, there has been a lot of information from people regarding the level of effectiveness of masks. Due to the fact that information is updated too quickly, it is very difficult to establish what actually works and what is not useful.

Laura Kwong took part in a study that examined the effectiveness of masks. At the moment, it has not yet passed the peer review stage, but it was very well received by the medical staff. The main conclusion from the study was that masks can indeed reduce the risk of COVID-19 infection.

The work was carried out on the territory of Bangladesh. More than 341 thousand adults who lived in 600 villages took part in the experiment. In half, the masks were worn at the request of local residents. In 200 villages, experts suggested using only surgical masks, and in another 100 – cloth masks. All adults were offered masks, as well as detailed information regarding the dangers of coronavirus.

As a result of the study, it was found that the efforts of scientists led to the fact that the process of wearing masks increased from 13% to 42%. At the same time, in 300 villages where masks were worn at will, the number of coronavirus infections decreased by almost 9% when compared with the control group of settlements. In places where surgical masks were used, the incidence rate fell by 12%.

Laura Kwong noted that surgical masks are the best to reduce the risk of infection. Of course, fabric products also bring a positive result, but preference should be given to a better and more efficient option.
