Federal and state officials in Florida have confirmed four cases of the Zika virus in the Sunshine State are the first locally transmitted infections in the continental U.S.

"We learned today that four people in our state likely have the Zika virus as a result of a mosquito bite," Gov. Rick Scott said during a press conference Friday. "All four of these people live in Miami-Dade and Broward Counties, and the Florida Department of Health believes that active transmissions of this virus could be occurring in one small area in Miami."

Some residents have begun taking matters into their own hands, saying they are stocking up on mosquito repellent and planning to bring lunches to work instead of sitting at outdoor cafe tables in the Wynwood area.

The director of the U.S. Centers for Disease Control and Prevention (CDC) said Friday there were no plans to recommend limiting travel to South Florida.

More than 1,650 Zika infections have been reported in the mainland U.S., but none of the cases involved bites from local mosquitoes, the Associated Press reports. The four people in Florida are believed to be the first ones to contract the virus within the 50 states via mosquito bites.

Prior to these cases, fourteen infections were sexually transmitted, and one lab worker was stuck with a contaminated needle.

Mosquito control inspectors in Miami have been going door-to-door in the area of investigation, spraying to kill mosquitoes and emptying containers of water mosquitoes need to breed, according to the AP.

In most people, Zika causes only a mild and brief illness, but it can provoke fetal death and severe brain defects in the children of women infected during pregnancy. Currently, there is no vaccine, and the main defense is to avoid mosquito bites. Zika can also spread through unprotected sex with someone who is infected.

"If I were a pregnant woman right now, I would go on the assumption that there's mosquito transmission all over the Miami area," Baylor College of Medicine tropical medicine expert Dr. Peter Hortez told AP.

According to Hortez, while these four recent cases have been reported, there are probably more that have not been diagnosed, and people should not be surprised if mosquitoes are soon found to be spreading Zika in Louisiana and Texas, as well.

Health officials worldwide have advised people preparing to have children not to travel to areas with a high risk of Zika, but these and other warnings have applied to countries and regions where outbreaks have spread far and wide.

It remains to be seen how many Zika infections would have to be confirmed in an area before state or federal officials issue similar warnings for parts of the U.S. mainland.
