The spread of the D614G mutation in the COVID-19 in Europe, North America and parts of Asia has coincided with a drop in mortality, India Today reported referring to scientists from the National University of Singapore.

The results of their research suggest that the virus with this mutation is less lethal. More specifically, strains with this mutation are more infectious but less lethal.

Scientists discovered this mutation back in February, according to the World Health Organization (WHO), and it has spread to Europe and America. The WHO also said there was no evidence that the mutation led to the development of the more severe disease.

However, the discovered D614G strain is 10 times more infectious than the original one, and it is believed that the vaccines currently being developed may be ineffective against this mutation. On the other hand, many independent experts are assured that vaccines will work, because the changes that occur as a result of mutation are not so dramatic.
