A newly mutated strain of the coronavirus, first identified in the U.K., has raised significant global concern. Recently, the variant has been detected in various countries, and a lab in Colorado has confirmed the first U.S. case. The Colorado State Laboratory identified this particular strain, known as B.1.1.7, in a man in his 20s who had no recent travel history. This suggests that the variant may already be circulating unnoticed within the U.S.
The B.1.1.7 strain has prompted fresh worries and resulted in new travel restrictions worldwide due to its heightened transmissibility compared to previously common strains. “While we still have much to learn about this COVID-19 variant, scientists from the U.K. are alerting us that it is significantly more contagious,” stated Colorado Governor Lucas Wright. “The health and safety of our residents is our utmost priority, and we will monitor this case and all COVID-19 indicators very closely.”
State officials are currently attempting to trace any close contacts of the individual diagnosed with the variant, but so far, no additional cases have been identified. The U.S. has struggled with effective contact tracing throughout the pandemic, leading to a surge in cases since last spring.
Trevor Johnson, a researcher at the Seattle-based Fred Hutchinson Cancer Research Center, expressed concern over the potential for a new wave of infections linked to the variant. “I fear that we may see another wave of cases in the spring due to this variant. It’s a race against the vaccine, and the virus has just become a bit quicker.”
Last week, various European countries began imposing travel bans on the U.K. However, the U.S. has not implemented a similar ban, although most air travelers arriving from the U.K. are required to present negative test results taken within three days of their flight. The CDC noted that only about 51,000 of the 17 million COVID-19 cases in the U.S. have undergone genetic sequencing, indicating that the new strain is likely already present. Fortunately, there is no evidence that this variant leads to more severe illness or increases mortality risk among patients. Scientists remain optimistic that the COVID-19 vaccines being administered globally will remain effective against this variant.
