Scientists have found evidence that the coronavirus may be mutating and adapting to humans. Analysis of over 5,300 coronavirus genomes from around the world showed that some strains have gained mutations in the spike protein that the virus uses to infect cells. While the mutations are still rare, they arose independently in different countries and may help the virus spread more easily. Scientists are concerned that more extensive mutations could impact the effectiveness of potential vaccines and treatments being developed that target the spike protein. Ongoing surveillance is needed to monitor any changes in the virus.
