Florida health authorities reported finding evidence of the latest US case of the new and apparently more contagious coronavirus strain first seen in England, saying it was detected in a man with no recent travel history.

The case, disclosed in a Florida Health Department statement, comes after reports in recent days of multiple individual cases of the United Kingdom strain of Covid-19 discovered in Colorado and California.

Florida's health statement said the new virus variant was detected in a man in his 20s in Martin County, which abuts the Atlantic Coast above densely populated South Florida.

It said its experts were working with the Atlanta-based Centers for Disease Control on investigating the case, AP reported.
