CDC: Virus variant may fuel increase in cases
Federal health officials sounded the alarm Friday about a fast-spreading, far more contagious variant of the coronavirus that is projected to become the dominant source of infection in the country by March, potentially fueling another wrenching surge of cases and deaths.
In a study released Friday, the Centers for Disease
Control and Prevention said its forecasts indicated outbreaks caused by the new variant could lead to a burgeoning pandemic this winter. It called for a doubling down on preventive measures, including more intensive vaccination efforts across the country.
The variant is not known to be more deadly or to cause more severe disease.
Only 76 cases of the variant have been identified so far in the U.S., but the actual number is believed to be higher and is expected to spiral upward in the next few weeks, officials said. They emphasized that current mitigation strategies were effective against the new strain, exhorting Americans to be vigilant in wearing face masks, maintaining at least 6 feet of distance from other people, washing hands frequently, reducing interactions with people outside their households, limiting contacts and avoiding crowds.
The new variant, called
B 1.1.7 was first identified in Britain, where it rapidly became the primary source of infections, accounting for as many 60% of new cases diagnosed in London and surrounding areas.
It has since been detected in at least 30 countries, including the United States and Canada.
Overall, at least 3,973 new deaths and 238,390 new cases were reported Thursday, and the nation has logged more than 390,000 deaths.
