The number of viral particles required for infection in the delta coronavirus strain is ten times less than that of the original Wuhan strain, so this variant of the virus spreads faster. This was stated by the head of the Vector Research Center Rinat Maksyutov on the air of the Russia 1 TV channel.
“We have shown [during research] that the amount of virus needed to infect an animal is ten times less. The “delta” variant is more efficiently transmitted from an infected organism to an uninfected one, “the specialist explained.
Earlier, an infectious disease specialist, Doctor of Medical Sciences Nikolai Malyshev, in a conversation with RBC, said that the delta coronavirus strain is more “harmful”, since its infectiousness is several times higher.
“Previously, there was evidence that the infectivity was twice as high, now they say that the infectivity is about three times higher. This strain is more harmful, ”Malyshev pointed out.
He also noted that in the case of the “delta” strain, more people are sick, respectively, and the mortality rate is also higher.
In mid-July, the World Health Organization (WHO) announced that the SARS-CoV-2 “delta” coronavirus strain, which is highly infectious, could soon become the dominant one in the world. The “Delta” variant is now present in more than 111 countries, and we expect that it will soon become the dominant strain of COVID-19 circulating around the world, if not already, “said the head of the World Health Organization (WHO) Tedros Adan Ghebreyesus. …
