The concentration of coronavirus Delta strain in the upper respiratory tract and blood is thousands of times higher than of other strains. But its incubation period is half less. This was reported by Mykola Habrykevych, Acting Director General of the Khmelnytsky Regional Center for Disease Control and Prevention of the Ministry of Health of Ukraine, as Suspilne.Podilya reports.
The incubation period for the Delta strain is 3-7 days on average.
"Delta-strain is characterized by the fact that it has an incubation period of less than half, on average from 3 to 7 days. In patients, the disease is more severe. If we appeal to research, then in the upper respiratory tract it is thousands of times more than the virus that was a year ago. It is also a thousand times more in blood," Habrykevych said.
According to the doctor, the Delta-strain currently predominates in Khmelnytsky region.
"Among those who are treated in the hospital, there are only a few vaccinated. I was in Kamianets-Podilskyi Hospital, where out of 100 patients there was only one person who was vaccinated and with only one dose," he added.
