DeSantis’ spokeswoman, Helen Ferrer, also tweeted out that New York’s first person-to-person case of COVID-19 traveled to Miami recently. Yet, the details of the man’s travels in South Florida were unknown.

New York state officials did not alert Florida health officials, who learned that the man traveled to Miami late in February only when it was reported in the media. The New York attorney became ill on Feb. 22, was admitted to the hospital Thursday and diagnosed with COVID-19 this week.
