Japanese scientists found out that the Omicron-strain of coronavirus infection is more resistant to the earlier options of COVID-19 and can linger on plastic surfaces and a man’s skin longer. So researchers explained the high infinity of the new strain. The results of the study are published on the Biorxiv portal.
Specialists analyzed differences in resistance to the effects of the environment on the variants of the Coronavirus of Wuhan type and all the options that appeared later.
“on the surfaces of plastic and skin variants of alpha, beta, delta and oomikron held more than twice as long as Wuhan type, and retained contagious more than 16 hours on the skin surface,” the researchers said. According to scientists, the high stability of these variants of coronavirus infection can increase the risk of contact transmission and promote their distribution.
on plastic surfaces The average time for the survival of the original Wuhan strain and variants of Alpha, beta, Delta and Omicron made up 56, 191.3, 156.6, 59.3 and 114 hours, respectively. Omicron strain lasted 193.5 hours, which is equivalent to eight days.
On the skin, the new strain is kept for more than 21 hours. It is specified, on the samples of the skin of the corpses, the average survival time of the Wuhan strain was 8.6 hours, for the alpha option, 19.6 hours, for beta – 19.1 hours, for the range – 11 hours, for the Delta version – 16.8 hours.
Previously, the Department of Clinical and Analytical Work of the Central Epidemiology of Rospotrebnadzor Natalia Wheat said that during Oomikron, the asymptomatic course of coronavirus could meet those who passed the vaccination course against COVID-19 or recently sober. In this regard, it is still preserved the need to wear masks, regardless of whether a person was sick or was a vaccination, she explained.
