Mark strassmann is there. Reporter zika anxiety pushed teams of mosquitocontrol sprayers into florida today. Floridas hot, humid client puts its 20 million residents at risk for the virus along with millions more tourists. Governor rick scott. Were state that has mosquitoes similar to mosquitoes that could carry this, so its better to get ahead of it. Reporter scott has asked the centers for Disease Control or c. D. C. To rush 1,000 zika testing kits here. The state will buy 4,000 more. Testing would focus on pregnant women who are especially vulnerable. The virus has been linked to a birth defect called microcephaly. Babies are born with abnormally small heads and brains. There is no zika vaccine and no antidote. Dr. Walter tabachnick, an expert on infectious diseases. I think we have to take this Everything Possible to reduce the chances of getting zika. Reporter floridians often live with standing water where mosquitoes breed, but residents are being urged to get rid of it, inside in flower vases and water tanks, and outdoors in empty pails, clogged gutters or wherever water pools. The c. D. C. Has advised pregnant women to postpone traveling to 30 countries and territories, including mexico. Im 16 weeks pregnant. Reporter Erica Benstock declared her own state of emergency. She has canceled her trip next month to cancun, where she was supposed to be matron of honor in her sisters wedding. Now that its in the state of florida, how far is it going to spread and what does that mean for everybody who isnt traveling . Reporter because you could stay home. And still get it. Reporter 80 of zika patients show no symptoms. Scott, its likely there are many more cases than the official numbers indicate. Pelley Mark Strassmann in the c. D. C. Says zika is spreading in these 26 countries and territories in the americas. In addition to mosquitoes, its transmitted through sex, and we learned today blood transfusions. Dr. Jon lapook has been reporting all week from ground zero of the outbreak in brazil. Reporter here in brazil, donated blood is not yet tested for zika virus. Instead donors are asked if theyve recently been ill, but since 80 of people with the virus have no symptom, selfreporting misses most infections. In brazil the virus is predominantly spread through mosquitoes, but in the United States, nearly all the reported cases are imported from travelers. Thats why the major blood banks say people should not donate blood if they have traveled in the last 28 days to mexico, the caribbean, south or central america. The director of transfusion medicine at u. P. M. C. Care of the great majority of the risk, so i think by far the benefits of transfusion would outweigh the very small risks of an infected unit. Reporter there is a test called p. C. R. That can detect zika virus in the blood, but its not government approved in brazil or in the United States where about 21 Million Units are transfused each year. Frozen. Reporter researchers rafael franka has been studying zika closely at this laboratory in brazil. Technology to do. This we need to make sure we have solid results. Reporter theres nothing really stopping you from testing every blood transfusion for the presence of zika virus . Yeah, true. We just dont have enough time actually. Reporter if mosquitoes in the u. S. Get infected, travel bans alone would not be an effective screening method. Blood for the preds accident of zika virus would be considered. Pelley jon lapook in brazil for us tonight. John, thank you. Now, five days before the New Hampshire primary, a poll out this evening shows donald trump leading marco rubio by 11 points. Thats a sevenpoint improvement for rubio, putting him ahead of ted cruz. Trump is looking for a comeback and Major Garrett is there. Reporter donald trump is learning retail politics means more than selling hats and tshirt. Okay. Lets go. Donald, we love you. Reporter it means mingling with voters, something trump rarely did in iowa. Got to do it. Its crunch time, right . Reporter crunch time is right, and trumps ad hoc ground game is hurriedly playing catchup. Trump has led every poll here since july, but today would not predict victory. I dont think in terms of losing. Thats why im here right now. I think were going to do well. Donald trump is very rattled he told the entire world he was going to win iowa, and then he didnt win. Report iowa caucus winner ted cruz is trying the maximize his momentum to catch trump and beat back another challenge from marco rubio. I really appreciate your support. Reporter marco rubio picked up Rick Santorums endorsement yesterday, but this morning santorum did little to help the florida senator. List one accomplishment that marco rubio has achieved in four years of the United States senate. It doesnt even have to be a passed bill. The bottom line is there accomplishments, joe. Question. Reporter rubio quickly downplayed santorums comments. I wouldnt expect him to be entirely familiar with my record in my time. Were electing a president of bencher to the United States senate. Reporter jeb bush has made an issue of rubios lack of experience all week. Today the super pack supporting bush featured its first tv ad i know jeb. I know his good heart and his strong backbone.

Hillary Clintons Campaign has been facing questions about her decision as secretary of state server in her home for official emails. Some of those emails turned out to contain topsecret information. Well, today we learned that clinton is not alone, and we this. I will be a better president. Reporter clinton suddenly finds herself in good company. According to an internal state department review, two of former secretary Colin Powells personal emails also contained classified information, as did ten emails from the personal account of top aides to his successor, condoleezza rice. Most of them i think are pretty benign. Reporter like clinton, Lauren Powell exclusively used a personal account as secretary of state, though he emailed far less often. In a Statement Today he said the two emails in question were from my executive assistant and forwarded messages sent by two of our ambassadors to state Department Staff members. I have reviewed the messages, he said, and i do not see what the Clinton Campaign happily sided with him. Press secretary brian fallon. This is an example of overclassification run amok. Reporter the state department announced last week that 22 of clintons emails which sat on her private server for years are being reclassified as top secret, one of the highest levels of classification, higher than the secret and confidential designations given to the powell and rice emails. More than 1,500 Clinton Emails have already been put in those categories. Isnt there a big difference between an email or two being classified as confidential and 22 emails being classified as top secret. These emails that have been judged top secret are completely wrong. We want them released. Let the public see them. Reporter f. B. I. Is still looking into clintons use of a private server, but, scott, the Clinton Campaign views this as a rare positive development in a yearlong controversy.
