Discovery of virus variant in CO and CA alarms scientists

The variant’s arrival also makes it all the more imperative that Americans receive vaccinations in great numbers, and more quickly, scientists said. A pathogen that spreads easily is more difficult to contain, and a greater percentage of the population must be inoculated to turn back the pandemic…

[G]iven the mutant’s apparent contagiousness, scientists fear that its toehold in the United States augurs another difficult chapter in the pandemic. Gov. Gavin Newsom of California announced on Wednesday that a case of the variant had been discovered in the state.

Officials in San Diego County later identified the patient as a 30-year-old-man who had not traveled outside the United States, suggesting the virus was transmitted by someone else in the community — a sign that the new version is already spreading. A household contact of the man has developed symptoms, the officials said, and is being tested.
