Rose good evening. Scott is off tonight. Im charlie rose. The number of people infected with the zika virus in florida has grown by ten. That brings the total now to 14. 12 men and 2 women. In making that announcement today, the centers for Disease Control and prevention took the unusual step of issuing a travel advisory for the area where the virus has been transmitted by mosquitoes. David begnaud is in miami. Reporter the travel advisory is for pregnant women to stay away from the onemile area known as the zika zone. Its north of downtown miami and made up of the wynwood and edgewater communities. The c. D. C. Says pregnant women who traveled here since june 15th should be tested for zika. That is the earliest date officials think anyone was infected. Pregnant women living in the zone should be tested in the first and second trimesters. The Borinquen Health clinic at the edge of the zika zone is handing out repellent to pregnant women. Dr. Diego shmuels is director of clinical operations. Your clinic is right inside the zika zone. What are you doing starting today thats brandnew . So basically weve just started to make sure that all pregnant women, symptomatic or asymptomatic, are going to get tested for the zika virus. Reporter convincing women to protect themselves is proving to be a challenge. Quendra gomez came in for an exam wearing short sleeves. Will you start being better . I have to actually. I do have the start wearing long sleeves and wearing repellent more. Reporter Health Officials insist both are a necessity for expectant mothers. Dr. Tom frieden, director of the c. D. C. , says intensive mosquito spraying inside the zika zone is not working as well as officials hoped. That could be because some of the mosquitoes are resistant to those insecticides or they havent gotten rid of all the standing water or simply this is a tough area to control the mosquitoes in. Reporter rosemary labranch was told her father was told today he has been tested for zekea. Hes been told to take precautions. When he comes outside, put the long sleeves and long pants on his legs. Report the c. D. C. Is sending an Emergency Response team here to south florida to help manage the spread of the virus. Charlie, were in wynwood. Its the heart of the zika zone, and its an urban hot spot popular punks artists and place where locals and tourists love to come. Rose thanks, david. Dr. Anthony fauci is director of the National Institute of allergy and infectious diseases. Dr. Fauci, thank you for joining us. We have seen Remarkable Growth over the weekend from four cases of local transmission to 14 cases. Does that suggest were facing exponential growth . Not necessarily, charlie. It is not unexpected that youre going to see clusters of cases, particularly in a place like florida, which has so many travelrelated cases that mosquitoes can then feed upon and locally transmit it to individuals, as were seeing in that small area just north of miami. Its something you dont take lightly and you take very seriously, and what it triggers is going to be a very aggressive mosquito abatement and mosquito removal and control campaign, because thats the way you stop this from becoming sustained and disseminated. Rose whats the most troubling about this for you . Well, the most troubling of it is that any time you have a tragic situation of a baby being born with a congenital abnormality, its something you have to go all out to try and avoid. Pregnant women, charlie, no matter where you are, in the summer right now should be careful about making sure they protect themselves from mosquito bites, not only insect repellent and proper clothing, but staying indoors. When the c. D. C. Comes out with a travel alert, you should not travel to those areas. Right now the place where theres a travel alert is in that circumscribed area just north of miami. Rose dr. Fauci, thank you. President obama made an urgent request of dong approve 1. 9 million in the battle against zika way back in february. Nearly six months later, no action has been taken and the house and senate have gone on summer recess until after labor day.

For the past six weeks, local militias have been trying to flush them out. Today u. S. Air strikes provided relief. Harrier planes and a predator drone strategically bombed an isis tank and two vehicles. Pentagon spokesman peter cook.

Reporter thousands of foreign fighters have poured into libya since 2011 after a natoled air campaign forced dictator moammar qaddafi out, leaving a power vacuum. Today libyas new prime minister, in office just five months, said he asked the u. S. To continue this strike but promised no american Ground Troops will join the fight. Charlie, u. S.

A new cbs news poll out tonight Shows Hillary clinton has opened a sevenpoint lead over donald trump since the Democratic NationalConvention Last week. It is now clinton 46 , trump 39 . Trump is under fire from both democrats and republicans over his comments about the parents of a fallen american war hero. Here is major garrett. Donald trump, youre asking americans to trust you with their future. Let me ask you have you even read the United States constitution . Reporter that challenge, issued by khzir khan, the father of fallen army captain humayun kahn, has cast a lingering shadow over Donald Trumps president ial campaign. Trump questioned the right of kahn to criticize him and implied his wifes silence was because of her muslim faith. She was standing. There she had nothing to say. She probably.

Reporter at Arlington National cemetery, we met the dowells who were there to visit a Family Members gave but were drawn to captain kahns resting place. Jake dowell said trump has wronged the kahns. Donald trump is just trying to take away the power of the situation and the amazing sacrifice he made and the amazing bravery both of his parents displayed going up there. Reporter tony dowell said trump set this controversy in motion long ago. The politicisation of this began with mr. Trump attacking people of the muslim faith. Hes been doing it for a year. It deeply saddened me. Reporter carlene cross, a gold star mother, whose son jason bogar died in this 2008 battle in afghanistan, described how she and other gold star families feel blindside i by trump. At least honor the familiarly, honor that ultimate sacrifice, and i think gold star families are confused, you know, that this could actually even be spoken from someone aspiring to be president of the United States.

There is no classified material. Was that true . There was classified material emailed.
