According to Hancock, both strains were found in people who had recently traveled from South Africa. Now these patients and contact persons are self-isolating.
"This new variant is highly concerning, because it is yet more transmissible, and it appears to have mutated further than the new variant has been discovered in the UK," UK Health Minister said.
As we reported earlier, a new strain of Covid-19 was recently found in the UK.
It has also been detected in Denmark, Australia, Italy and the Netherlands. Boris Johnson said that the new strain may be 70% more infectious than the common one, and it is for this reason that the reproductive index may increase by 0.4, showing the dynamics of the growth in the number of new cases of coronavirus infection.
