Are there two strains of the virus, one mild and one severe?
No, there are not two strains of the coronavirus going around in the United States or elsewhere.

A study published March 3 in the National Science Review claimed that two types of the virus, which had varying severity and were called L and S, were infecting people. The researchers had studied viruses from 103 people, and found that some viruses had a particular mutation. Those viruses, the L type, were more prevalent in Wuhan, China, in the early stages of the outbreak, and produced more severe symptoms, the team concluded.

But that mutation doesn’t change any of the virus’s proteins and probably has no effect on disease severity, experts say. “The differences between [the two virus types] … can be likened with comparing two cars of identical type and color, just with a different license plate. That license plate helps you find out where the car was registered but not how fast it can go,” say researchers from GISAID, a repository that has been collecting all of the coronavirus genomes deciphered so far.
