As many of us knew from the beginning, masks are the most effective method to stop the transmission of any virus in our daily lives. We were aware of this since for years, it is the tool most used by workers in the health sector to treat patients with diseases of any kind and preserve their health.
Even so, many people have questioned the effectiveness of the masks, a branch of deniers and unwary have emerged who have decided to ignore the professionals and their warnings.
That is why in the United States they have decided to conduct a study on their effectiveness, and thus be able to make clear once again how important they are for our daily use. The journal The Lancet Digital Health, published an observational study in which they studied 300.000 people.
In the study, it can be seen how an increase of 10% of the population of the United States using masks has managed to stop the spread of the infection within the country, has multiplied by three the possibilities of maintaining the instantaneous reproduction ratio, in short In other words, the disease was already slowing down but thanks to its use it has slowed down even more.
Scientists from different hospitals within the US, including Boston Children's Hospital, state that this study is not definitive and they do not want to draw hasty and definitive conclusions about transmission and its ratio.
It is commented that this study has not taken into account different factors that may influence the study and that are very important for it, such as, for example, people are more cautious, wash their hands more or do not leave their homes as much because of fear. But although it is not the only factor that has influenced these consequences, it is true that the use of a surgical mask has helped and has an important intervention.
As we all know, today the use of masks is mandatory in most countries, especially those that have been affected by this pandemic. Its objective is to act as a barrier and shield to protect us from possible droplets that could enter our respiratory system, and until now, surgical masks that have high filtration such as the IIR or FFP2, they are fulfilling their function.
Although the data from these analyzes appear to be somewhat heterogeneous, the conditions of conducting a randomized study are very difficult to follow. It is clear that the use of masks is beneficial to society, as they have been shown to reduce the spread of viruses that are emitted in the breath, breathing and speaking.
From Mascarillas Béjar we recommend the use of masks and respecting safety measures at all times.
