It’s not too late to curb the contagious variant’s spread in the U.S., experts say — but only with a national program for genetic sequencing.
With no robust system to identify genetic variations of the coronavirus, experts warn that the United States is woefully ill-equipped to track a dangerous new mutant, leaving health officials blind as they try to combat the grave threat.
The variant, which is now surging in Britain and burdening its hospitals with new cases, is rare for now in the United States. But it has the potential to explode in the next few weeks, putting new pressures on American hospitals, some of which are already near the breaking point.
The United States has no large-scale, nationwide system for checking coronavirus genomes for new mutations, including the ones carried by the new variant. About 1.4 million people test positive for the virus each week, but researchers are only doing genome sequencing — a method that can definitively spot the new variant — on fewer than 3,000 of those weekly samples. And that work is done by a patchwork of academic, state and commercial laboratories. Continue reading.
