Scientists report the spread of the Delta strain subspecies.
The mutated variant is thought to be more infectious than its predecessor. In England, its rapid spread is recorded. For a month, the number of diseases they have doubled. It is designated as AY4.2. Now it accounts for 10 percent of diseases. And in some places he manages to oust his relative.
According to British doctors, it is about 15 percent more infectious than the original Delta, and clearly stands out for its activity among the 45 subspecies of Delta. Although there is no evidence yet of its greater lethality.
It is believed that this subspecies evolved as schoolchildren returned to school and company employees filled their offices.
Epidemiologists said with dismay that the fourth wave of the pandemic could be formed by the end of the year, so urgent efforts are required to have time to vaccinate as many people as possible.
Thanks to more extensive vaccinations than in Russia, especially for the elderly, British doctors manage to avoid high mortality.
