WHO : UK Covid19 variant detected in 86 countries
The World Health Organisation recently announced that the coronavirus variant B.1.1.7 , which was first identified in United Kingdom has now been found in 86 countries. The variant B.1.1.7 has shown an increase in transmissibility and some evidence and some increase in disease severity.
In the UK, for example, Covid-19 test samples of this strain increased from 63 per cent in the week of December 14 to 90 per cent in the week of January 18, the WHO said in its weekly epidemiological update.UK Prime Minister Boris Johnson also termed the strain as a more deadly and mortal form of coronavirus and said that it is associated with a higher degree of mortality.
The WHO has also been monitoring two additional coronavirus strains that are actively spreading: B.1.351, initially seen in South Africa, and the P.1 strain that was first identified in Brazil.
The new variants have the E484K mutation, which occurs on the spike protein of the virus, which is the same change as has been seen in the South African and Brazilian variants that have caused international concern. Public Health England has now identified 76 cases of the new variants and is confident that vaccines will work against them.
