There's a lot left to learn about Covid-19's Lambda variant, which is still rare in the US. Here's what experts know so far.
Coronavirus variants: Here's what we knowGenomic sequencing has identified 1,060 cases of Covid-19 caused by the Lambda variant in the United States so far, according to the independent data-sharing initiative GISAID. While that number is a far cry from the surge in cases caused by the Delta variant -- representing about 83% of new cases in the US -- infectious disease experts have said that Lambda is a variant they are watching closely.
Overall, Poland, the Mayo Clinic professor, warned that the more people don't wear masks and remain unvaccinated, the more likely additional variants will emerge in the future -- including one that might evade vaccines completely. Because as the coronavirus continues to jump from person to person, with each new infection, it changes a little bit -- just like any virus does -- and those changes or mutations could either be benign, or make it more easily transmissible and dangerous.
