Experts told The Daily Beast that the U.S. Centers for Disease Control and state health authorities aren’t sequencing nearly enough COVID samples.

It’s a problem. “Without continual surveillance efforts, we are effectively flying blind in terms of the risk from emerging variations of this and other pathogens,” Christopher Mason, a biophysicist at Weill Cornell Medicine in New York, previously told The Daily Beast.

Ramping up monitoring requires more technicians in more labs getting wider access to bigger sets of samples from doctor’s officers, pharmacies, hospitals, and other testing sites.

And then there’s all the computing. “The files are large, the data transfers are slow, and the computational pipeline can take hours or days to run depending on data volume,” Rob Knight, the head of a genetic-computation lab at the University of California, San Diego, told The Daily Beast.
