they called it the zika virus. it is spread almost exclusively through the bite of a mosquito, an aggressive daytime biter they have been diminished in the united states until the resurgence of dengue and chicken ghunga. we know a great deal about them but there is much scientists add mits they don't know about the virus. some of the reasons we don't know more about the disease include a small proportion, one in five, develop symptoms. it is only detectable for a few days in infected people's blood. the failure of current tests distinguished zika from current viruses. the ambassador to the united states, the brazilian government has deployed 220,000 troops and 300,000 health agents to fight the vector of the infection by visiting communities to educate the population and help eliminate all mosquito breeding grounds. experts cite links with the zika infection of pregnant mothers and disorders affecting unborn children. they are quick to point out no definitive link. according to brazil's ambassador micro cephaly in

zika is a virus on the move. the world health organization has declared the mosquito-born illness a global health emergency. there have already been an estimated 1.5 million cases in the hemisphere. some 3700 each in honduras and venezuela. many infected have only experienced minor systems, but far more frightening are the babies being born with microcephaly. my guests are still with me, and doctor, before the break, we were talking about how that link with microcephaly has not been nailed down. similarly the transmission through sexual contact in the texas has not been confirmed. how important is it to nail those variables down? >> sexual transmission is less important. we had a case reported in 2008 in colorado. but this microcephaly link is novel avenue, and driving the public health response among citizens, so this is very, very important. a lot of these actions are premised on the fact that this is microcephaly. so we need to make sure we get this right, that there are not other factors involved. and you mig

know about the zika virus? researchers in brazil are saying that potentially this could be spread through saliva. what's most concerning to you about what you don't know? guest: what's theoretically possible and happening are two things. zika is spread by mosquitoes. they are tough to control. it will bite four or five people at one blood meal. they can breed in the amount of water it takes a fill up a bottle cap. or theoretically even a drop of water. you have to get rid of maybe 90% of them or more before you protect people. so for me the immediate challenge is getting the best mosquito control into places this is spreading and doing everything we can to inform and provide services and protection to pregnant women to reduce their risk of getting the zika infection. >> doctor, can you step back and put the threat of zika in perspective? where does this rank in terms of health threats facing americans? guest: every health threat has a different nature and characteristic and appropriate response. zika is a parti

since the last major zika outbreak in 2007, the cdc produced a test to detect zika in a sample taken from an infected child. more recently, the cdc activated its emergency operations center last month in response to this latest outbreak and on february 1, the world health organization designated the outbreak a public health emergency of international concern. our public health system has acted quickly to increase its surveillance and diagnosis capabilities in infected areas and to ramp up what had been very limited scientific research on this virus. i want to thank the cdc and nih for their very hard work and rapid response in this case. however, much work remains to be done so that we can better understand the zika virus and develop proven strategies to treat infected individuals. to contain the virus' spread and ultimately to develop effective therapies and vaccines that will neutralize the threat entirely. further, we must work diligently to assess every available control measure and adopt the most effective policies to prevent the virus from entering the mosquito population in th

we'll learn about how long a man infected with zika may continue to harbor zika in semen. we'll learn more how to stop the vector, the mosquito that spreads zika virus. for all of these things we will need additional resources, which is why the emergency supplemental request is so important. so one thing that will happen is we'll learn more. a second thing that will happen is we will see more cases among travelers to the u.s. some of them will be pregnant. that's why we've issued travel advice, not travel if you're pregnant. and we've worked with doctors and clinicians and others to provide that advice. third, we will likely see significant numbers of cases in puerto rico and other u.s. territories where there may be intensive spread of zika. this is a particularly urgent area. and i'd like to show you a series of slides that show what happened in the chikungunya outbreak a little under two years ago. in may of 2014, may 5th of 2014, the first chikungunya case was identified in puerto rico. by two weeks later it had begun to spread. and each of these slides is a two-week p

that's very similar to zika. we need to get a very specific diagnostic to tell a woman particularly who's pregnant, have you been infected with zika or not? that's going to be very important. and we're working very closely on that. and finally, there's the issue with the vaccine. vaccines are very important. the good news is that zika is what we call a certain class of virus ps and we have successfully developed vaccines against flavi viruses like yellow fever. we're studying that right now. we have already started to develop a vaccine and we can predict that we would likely be in phase one trial just to determine if it's safe and in it produces a good response, probably by the end of the summer and get that going by the end of this year, and if it looks like it's safe, we'll go to the next stage. unlikely to have a vaccine that's widely available for a few years. but we certainly can get the initial steps. again, happy to answer any questions. >> you said once we clear the virus, we're not able to tell if someon

which could spread the zika virus. we look at a comprehensive approach, so on the one hand the things you can do to reduce larval populations and their use two different bacteria to actually kill the larval most egos are very effective -- mosquitoes are very effective. there are other ways of reducing mosquito populations, but that is one of them. adult mosquitoes, there are three broad classes of insecticide. inside those are other classes of insecticide. not all are licensed for use in the u.s. and we are looking carefully at what is being done in other countries, including australia with targeted residual spraying and seeing what would be safe and effective here. that is something we are in frequent discussions with partners and epa and other entities. there are issues of what we could do that is safe and effective. the mosquito control efforts are more than just chemicals. it is about having a surveillance system, so cdc has invented a type of trap that can monitor what the mosquito populations are. populations can
