To date, 60 countries across all six World Health Organization regions have reported either imported cases or community transmission of the UK coronavirus strain -- 10 more than a week ago, WHO said in a news release Wednesday.

Among the countries which have reported cases of the variant first identified in the United Kingdom are the United States, Russia, Brazil, India and Spain.

US cases: On Monday, the US Centers for Disease Control and Prevention said that at least 122 cases of the UK variant have been identified in 20 US states.

This includes at least 46 cases in Florida; 40 in California; six in Colorado; five in Minnesota; four each in Indiana and New York; two each in Connecticut, Maryland, and Texas; and one each in Georgia, Illinois, Louisiana, Massachusetts, Michigan, New Mexico, Oregon, Pennsylvania, Utah, Wisconsin and Wyoming.

CDC said this does not represent the total number of cases circulating in the US, but rather those that have been found by analyzing positive samples. The agency cautions that its numbers may not immediately match those of state and local health departments.

While the variant, known as B.1.1.7, appears to spread more easily, there's no evidence that it's any more deadly or causes more severe disease, according to CDC.
