Of these, 107 occurred in 24 US states and 40 on the island of Puerto Rico. In a teleconference briefing with reporters, the CDC’s director, Tom Frieden, said that all of the 107 cases reported within the US had been travel related but that most of the 40 cases reported in Puerto Rico had been acquired on the island through local transmission. “There is the potential for hundreds of thousands of Zika cases in Puerto Rico,” Frieden said. On 26 February the CDC also reported on the cases of nine pregnant travelers who were infected with the Zika virus while traveling in areas where there is local transmission of the virus: American Samoa, Brazil, El Salvador, Guatemala, Haiti, Honduras, Mexico, Puerto Rico, and Samoa.
