The drop in Covid-19 mortality in Europe is tied with the spread of the new mutation of coronavirus, as Reuters reported, citing Paul Tambyah, senior consultant at the National University of Singapore and president-elect of the International Society of Infectious Diseases.
According to the infectious disease specialist, the D614G mutation of new coronavirus, which becomes more common in Europe and was recently detected in Malaysia, might be more contagious but less lethal. D614G mutation is also observed in Singapore.
Tambyah pointed on the presence of evidence that the spread of mutation in Europe coincided with the drop in the mortality. It enabled the scientists to conclude that this form of the virus is less lethal.
The mutation is not likely to influence the efficiency of the potential vaccine.
Tambyah noted that the majority of the viruses, usually, become less dangerous during the mutation.
“It is in the virus’ interest to infect more people but not to kill them because a virus depends on the host for food and for shelter,” he said.
On August 16, Malaysia’s director-general of health Noor Hisham Abdullah urged the community to be more careful as the authorities detected the D614G mutation of coronavirus in two clusters.
Noor Hisham stated that the detected strain is 10 times more infectious and the vaccines developed for today might ineffective in the fight against this mutation.
However, Tambyah underlined that such mutation is not likely to change the virus so much to make a potential vaccine to be less effective.
According to the WHO, the scientists detected the mutation in February and it spread in Europe and America. The WHO also stated that there is no evidence that the mutation led to more severe infection.
As we reported, Professor at Johns Hopkins School of Public Health and Virologist Andrew Pekosz stated whether coronavirus might be transmitted through food.
