Immunologist Kryuchkov: a new route of transmission of COVID-19 with a delta strain – air-dust 
A new route of transmission of COVID-19 with delta -the strain has become airborne (aerosol), said in a conversation with Ura.ru the general director of the contract research company “KEG”, immunologist Nikolai Kryuchkov.
He noted that particles of coronavirus are transported over long distances, in in particular, they can penetrate the ventilation system.
For this reason, Kryuchkov recommended to ventilate the premises more often. He is confident that this will result in a sharp decrease in the concentration of the virus.
Earlier, the virologist admitted that the meeting of two strains of COVID-19 in one organism could lead to the emergence of a new combined version. According to Kryuchkov, a hybrid option may not necessarily be dangerous. The likelihood of a meeting of two strains of coronavirus in the same organism depends on the path of spread in the population of the mutation that has appeared.
