Good Lifestyle

With Texas and California mandate statewide face masks and experts saying that face masks can be the only thing between you and Covid-19, the message is clear: wear your face mask. But what kind is preferable to prevent propagation? This is what a team from the University of Florida Atlantic University asked, and they say they have found the answer.

"The use of facial masks in the public parameters has been widely recommended by public health officials during the current Covid-19 pandemic. Masks help mitigate the risk of cross-infection via respiratory droplets; however, it there are no specific guidelines on mask materials and designs that are more efficient to minimize droplet dispersion, "say the authorsFluid physics. "We use qualitative visualizations of emulated cough and relaxes to examine how the materials of materials and design have an impact on the extent to which the respiratory jets loaded with droplets are blocked."

What works, which does not work

What does not work so well: "Furnished face masks and Bandana style coatings offer minimal stopping capacity for the smallest aerosolized respiratory droplets."

What works better: "Well-fitting homemade masks with several quilt fabric layers, and unpleasant cone-style masks, have proved to be the most effective to reduce the droplet dispersion. These masks have been able to significantly reduce the speed and range of jets Respiratory, although some fleeces through the material of the mask and small gaps along the edges. Especially, unrowed emulated cough has been capable of traveling in particular more than the 6 FT distancing directive currently recommended. "

The fact that the uncovered cough has been able to spread Covid-19 so far, it is a sufficient reason to carry a face mask because each droplet could spread the disease. "After being expelled into the ambient environment, the respiratory droplets have various degrees of evaporation depending on their size, size, ambient moisture and temperature, write the authors. "The smallest droplets can undergo complete evaporation, leaving behind the dried spherical mass consisting of the contents of the particles ... These dried nuclei, in combination with the smaller droplets, are powerful transmission sources."

Conclusions of life

The work of researchers is not only interesting; This can save lives. "Infectious respiratory diseases may require a heavy court on the most vulnerable members of our society, as has become evident from the current Covid-19 pandemic," report the authors. "The disease has a submerged health infrastructure around the world and its high contagion rate and its relatively long incubation period have made it difficult to trace and isolation of infected persons. Current estimates indicate that about infected persons do not have symptoms manifested and can contribute to the significant spread of the disease without their knowledge. "In order to contain the non-overall Community propagation of the disease," they continue "," public health officials have recommended The implementation of various preventive measures, including social distancing and the use of facial masks in public contexts ".

So: Wear a well-fitting homemade mask with several layers of quilt fabric, or a cone-off style mask, practice social distancing, wash your hands frequently, watch your health and cross this pandemic at your healthier, do not do not miss theseThings you should never do during the pandemic coronavirus.
