In the UK, there were cases of infection of lambda-strain coronavirus, common in South America, writes the Express newspaper with reference to the public health agency England.
Lambda option was initially revealed to Peru, Chile, Ecuador and Argentina at the end of 2020. It is assumed that this version of the pathogen contains several mutations in the spike protein that affect the degree of contagious. So far, scientists have no evidence that a new strain provokes a more difficult COVID-19 or weakens the effect of vaccines.
The World Health Organization introduced four SARS-COV-2 mutations to the list of concerns: Alpha strains (British), beta (South African), Gamma (Brazilian) and Delta (Indian). The latter continues to mutate.
At the end of last week, Maharashtra reported the appearance of Delta-Plus option (B.1.617.2.1). It is characterized by the presence of a K417N mutation in S-protein and can reduce serum activity and antibodies of persecuted and vaccinated people.
