A group of specialists from the University of Tokyo found that the delta coronavirus strain has the highest pathogenicity among other COVID-19 variants. This became known to the NHK TV channel, TASS reports.
Scientists conducted a study in which they artificially created viruses carrying the P681R mutation. This is the most common mutation for all strains of the Indian variation of COVID-19.
It also turned out that infection with COVID-19 destroys cells, which then fuse into a single mass called synthesia. In the course of an experiment with rodents, experts found that infection with a delta strain leads to an increased volume of synticia, 2.7 times the mass of similar formations when infected with other variants of the coronavirus. According to the researchers, it is this factor that causes a greater tendency to various kinds of pathologies.
Also, rodents infected with the virus with the P681R mutation lost 4.7-6.9 percent more in weight compared to the topic who was infected with other strains.
Earlier, an infectious disease doctor, chief physician of the Leader-Medicine medical center, Yevgeny Timakov, revealed the features of the postcoid delta-strain syndrome. The specialist suggested that he would more often affect the central nervous system.
