Crews went door to door in that neighborhood Saturday handing out kits and information, while mosquito control sprayed the area.

Saturday night the usually jammed sidewalks in the artsy and popular neighborhood were noticeably less so.

Health officials don’t expect the four newly-reported cases caused by mosquito bites to lead to a widespread outbreak.  But now that the state pinpointed the first U.S.-borne cases to Wynwood, people are starting to take it more seriously.

“We came from South America where the Zika is there,” said Federico Miller, who was visiting from Uruguay.  “And now we come here and we realize it’s here also.  So, we are scared about it.”

“My girlfriend came, we hopped on the Uber and she bought a whole bunch of bug spray and sprayed it on me,” Ty Stephano told CBS4’s Donna Rapado.   “I mean, I sprayed a few drops.  I’m fine.”

“It’s a little bit crazy,” Rajan Francois told Rapado.  He said he and his girlfriend had just discussed it on the way to Wynwood.  “I think people definitely need to be careful with the situation and it kinda worries us because we don’t know how severe it’s gonna end up getting.”

“Believe it or not, we really worry about it,” Gustavo Correa said as he carried a baby.  “Let’s see.  I hope they do something.”
