A new study has found that “Covid-19” and other similar strains of the virus can live on clothing and spread to other surfaces for up to 72 hours.
The study, conducted by De Montfort University (DMU) in Leicester, looked at the behavior of the Corona virus on three tissues commonly used in healthcare.

Scientists said that polyester poses the greatest risk of transmission, as the contagious virus persists after three days and can be transmitted to other surfaces.
The study, led by microbiologist Dr Katie Laird, virologist Dr Maitrei Shefkumar and postdoctoral researcher Lucy Owen, included the addition of droplets of a typical coronavirus called HCoV-OC43, which has a very structure and survival pattern. similar to those found in Sars-CoV 2. The virus that causes “Covid-19” to polyester, poly-cotton and 100% cotton fabrics.
Scientists said the virus lasted 24 hours on 100% cotton fabrics, while it was alive on polycotton (a fabric made from a blend of cotton and polyester fibers) for just six hours.
The university said Dr Laird had informed the government that all healthcare uniforms in hospitals should be washed to commercial standards or by an industrial laundry.
Dr Laird, head of the infectious disease research group at DMU, explained: “When the epidemic started, there was very little understanding of how much the coronavirus remains on textiles. Our results show that three of the most widely used textiles in healthcare pose a risk of virus transmission ”.

“If nurses and health workers take their uniforms home, they can leave traces of the virus on other surfaces,” she continued.
“Once we determined the survival rate of the coronavirus on each piece of fabric, we turned our attention to determining the most reliable washing method to remove the virus. While we can see from the research that washing these materials at high temperatures, even in a household washing machine, removes the virus, “she continued. This does not eliminate the risk of contaminated clothing. that leave traces of the Coronavirus on other surfaces in the house or car before washing them.
“We now know that the virus can live for up to 72 hours on some textiles and can also be transmitted to other surfaces. This research reinforced my recommendation that all healthcare clothing should be washed on-site in hospitals or in an industrial laundry. . These washing methods are regulated, “she added. This should not cause nurses and health workers to worry about the possibility of transmitting the virus at home.”
