China's Guangdong Provincial Center for Disease Control and Prevention announced on March 14 that the first confirmed case of infection with the Nigerian variant of the new coronavirus (SARS-CoV-2) strain B1525 was found in the local area.
Australian media reported on the 1st that so far, there is no suggestion that B1525 is more contagious or will cause more serious illness.
The news site The Conversation stated that there are several mutations in the gene responsible for the production of spike protein in B1525.
Acanthin plays a key role in infecting human cells.
Those mutations include E484K, which allows the virus to "cheat" the immune system to a certain extent.
E484K was first discovered in South Africa variant virus strain B1351 and Brazil variant virus strain P1.

The article stated that there is no data to prove that E484K means B1525, but more and more evidence shows that E484K may affect the efficacy of the new crown vaccine.
In the genome of B1525, its ribonucleic acid (RNA) has several deletions, and the British variant virus strain B117 also has the same deletions.
According to research conducted by Ravindra Gupta, a clinical microbiologist at the University of Cambridge in the United Kingdom, these deletions may double the infectivity of the virus in laboratory experiments.

In addition to China, countries such as Denmark, Australia and the United States have also found B1525.
B1525 was also detected in virus gene sequencing in France and Spain.
