It has come as a blow to Americans that first locally transmitted Zika case has been witnessed in Florida. Now there is concern about more such cases that may follow. Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said there is possibility that locally transmitted cases may increases, but not with the intensity as seen in Brazil or Puerto Rico.

So far, four cases of locally transmitted Zika infections have been reported, and there is possibility for the number to rise. Fauci said he do not think the number will stop at four and that there is almost a certainly that more people will get the infection, but the number may not climb too high. There are efforts in operation to reduce the number of mosquitoes in affected areas.

Masses can play a great role to keep themselves protected. Fauci advised people, especially those in affected areas to try to stay indoors most of the time and keep themselves covered. People are also recommended to use mosquito repellant to stay protected. As yet there is no Zika vaccine developed so far, individual protection becomes a need.

“We're making very good progress; it's really on a very fast track. I would say that we will very likely in the next couple of weeks go into the phase 1 trial in one of the several candidates that are being considered”, said Fauci about Zika vaccine, which is being developed. The "phase one" trials of one contender will likely begin in just a few weeks, then would be followed by wider trials in early 2017.

Fauci said it all would be difficult if Congress doesn't approve additional funding for the National Institutes of Health and other health authorities for the cause.

A report published in Business Insider revealed, "The United States will likely see more cases of local Zika virus transmission going forward, a U.S. health official warned on Sunday, although it is unlikely to turn into a broader situation as seen in Brazil or Puerto Rico."

The comments comes after Florida authorities on Friday reported the first sign of local transmission in the continental United States, concluding that mosquitoes likely infected four people with the virus that can cause a serious birth defect.

"We definitely don't take this lightly. This is something we always anticipated and prepared for the worst," Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, said during CBS' "Face the Nation" program on Sunday. "But we do not feel this is going to turn into that broadly disseminated situation that we've seen in Brazil or that we're seeing in Puerto Rico."

According to a report in Cbs News by Emily Schultheis, "With the first locally transmitted cases of Zika virus coming to light in Florida recently, a top expert on disease control said it's likely the United States will see further local cases going forward--but that it's highly unlikely the Zika situation will ever get as bad in the mainland U.S. as it has in Brazil or Puerto Rico."

"We're making very good progress, it's really on a very fast track," he said. "I would say that we will very likely in the next couple of weeks go into the phase 1 trial in one of the several candidates that are being considered."

"We're going to rapidly run out of money if we don't get it real soon because we're stretching it, borrowing money from other places to try and do those kinds of things," Fauci said. "We're getting to that critical point very quickly."
