Coronavirus falling on a cotton degrades in less than a day, found canadian researchers. The results of a study conducted by the University of Manitoba and the public health Agency of the country published on the portal medRxiv.
the Subject of the study was the stability of the virus on personal protective equipment from various materials. The virus was placed in a cotton protective mask, nitrile gloves, respiratory masks N-95 and N-100, nonwovens, plastic and stainless steel. Observations were conducted within three weeks. According to scientists, most likely, the virus was killed on cotton fabrics.
At the same time, scientists from the Foundation of William gates established that the masks of two layers of cotton with a density of 600 fibres with chiffon filtered more than 80% of particles smaller than 300 nanometers and more than 90% of particles larger.
In General, according to experts, the multi-layered mask made of cotton protects from the virus a little worse than a face mask, but it retains well respiratory droplets, which spread SARS-Cov-2.
