AdvertisementMore than 20 million Americans have been infected with coronavirus as of Friday afternoon. Another 227,315 new infections were confirmed on Thursday, bring the tally to 20,007,149, according to data from Johns Hopkins University. The fact that the confirmed cases in Colorado and Florida both involved individuals with no recent travel history means that the variant must already be circulating on US soil. Florida is ranked among the nation's top coronavirus hotspots, with more than 1.32 million cases and 21,673 deaths reported to date. Concerns have grown in recent days that the state's vaccine rollout plan could lead to even more infections, as long lines of high-risk elderly residents form outside vaccination sites.
