CNN With half of US states reporting a rise in new cases, one expert warns of 'danger signs' in some parts of the US. And public health measures meant to control infection aren't quite up to speed -- a problem the country has consistently faced in past months. According to Florida's health department, the state surpassed 100,000 total cases Monday and experts say it could be the next US coronavirus epicenter. Houston is "moving very fast in the wrong direction," said Mayor Sylvester Turner after the city recorded a new high of daily coronavirus cases, according to CNN affiliate KTRK. But experts say while testing is partly contributing, cases of the virus are also on the rise.
