葡萄牙发现三种新的冠状病毒变种正在传播

The World Wide Web released that on December 23, 葡萄牙国家卫生研究院发表的一项研究显示，葡萄牙发现三种新冠病毒变种正在传播.

Researchers conducted genomic analysis of the new coronavirus samples collected in different periods in Portugal and found that the three new variants of the new coronavirus are most commonly spread in Portugal. The genetic mutations (A222V, S477N and S98F) are all related to the spike protein. 70% is a variant that quickly spread throughout Europe after it appeared in Spain a few months ago. The most common variant in the first wave of the epidemic in Portugal and the new variant reported in December in the United Kingdom were not found in the case samples of the autumn and winter epidemic.

Researchers believe that the new variant virus may be more infectious.
