SARS-CoV-2 continued to mutate after that, with scientists tracking those genetic changes closely. This is crucial because mutations can make a virus more infectious or dangerous and can hinder drug and vaccine research. Several notable novel coronavirus strains have been found so far. The D614G mutation is believed to be responsible for the current status of the pandemic.
A few days ago, UK health officials announced that another new coronavirus mutation was spreading rapidly in the south of the country. The strain featured 17 distinct genetic changes, most of them impacting the spike protein. One of them is called N501Y, affecting the receptor-binding motif of the spike protein, according to the UK COVID-19 Genomics Consortium. The mutation did not appear to cause more severe illness, according to public health officials.
Now, a few days later, South African authorities have reported another SARS-CoV-2 mutation that’s apparently driving the second wave in the country. South Africa is nearing 1 million infections, with more than 24,000 people having died of COVID-19 complications. The second wave started in mid-November, with the country registering more than 10,000 cases in a single day a few days ago. This appears to be the second wave’s local peak, but the case count might continue to climb.
The new strain seems to be more dangerous, causing more severe illness in younger patients who do not suffer from other medical conditions.
