Colorado health officials have now confirmed five cases of a coronavirus variant that’s thought to be far more contagious as they step up surveillance for the version of the disease that caused cases to soar in the United Kingdom.
The latest confirmed case is in a person in their 20s in Boulder County, the Colorado Department of Public Health and Environment said in a news release Wednesday. Further details were not released.
The state says it will start sharing a daily count of confirmed cases of the variant, known as B.1.1.7. The variant is thought to be as much as 70% more transmissible than the regular strain of COVID-19.
CDPHE’s lab is now accepting a portion of coronavirus tests from across the state to better track the spread of the variant. The latest case, in the Boulder County person, was first confirmed by a private lab and then confirmed by the state.
B.1.1.7 is not thought to cause more severe symptoms, and coronavirus vaccines that have been developed are thought to be effective against it.
