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

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

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

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

since the last major zika outbreak in 2007 the cdc developed a test to detect zika in the first week of an illness or 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 the federal first wto designated it international concern to our public health system has acted quickly to increase surveillance and diagnosis capabilities in affected areas and to ramp up what had been very -- scientific research on this virus to our to and anna h. for rapid response in this case. however, much wor were commenceo be done so we can better understand the zika virus and developed proven strategies to treat affected individuals. to contain the virus is spread and ultimately to develop effective therapies and vaccines that would neutralize the threat entirely. further we must work till late to assess every available control measured at about the most effective policy to prevent the virus from entering the mosquito population and a continental united states. equally important in light of what appears

. >> zika is a particular risk for pregnant who are thinking of traveling to place where is zika is spread. that's the top level of concern. there maybe other problems wouldn't be surprised to see some cases of beyond the syndrome that can be severe. the bigger issue now is what can we do to protect pregnant women because devastation of having a child with a severe fetal abnormality who may die in the first days or years of life, who may have a long lasting stability, that's something we want to do. we are doing everything within our power to prevent it. >> jen mentionedded spread of ebowe-- ebola. there are concerns like countries that might not sharing their data in that way that will be helpful to the u.s. how are you working with those countries. what more can be done to coordinate these efforts? what do the next couple of weeks look like? >> we're seeing a good global collaboration. the tough part is the enemy. the enemy is nature. a nasty mosquito that's very hard to control and very effective in spreading viruses. we need information sharing. and we need to strengthen the ability of

well, zika and -- i believe dengue and zika are closely related. >> the same kind of mosquitos can transmit any of those as well as yellow fever. >> it is here now, in miami died d broward county. what can we do as resididts. >> what we're telling our residents is that they need to do their part. this is -- if anything happens metropolitan around here, it is going to be a community problem. it is not a my problem, your problem, it is everybody's problem. >> the mosquito hasn't been -- >> the mosquitoas been detected here. the mosquito loves here. the mosquito loves florida. but these guys help keep them under control in numbers so they are not enough of them to lead to epidemics. >> okay. >> okay. >> so what we're trying to tell our residents is they need to get out of the house, walk around and try to eliminate every single accumulation of water around the house. no matter the size. small accumulation of water -- >> standing water. container. this is also domestic mosquito or container mosquito because, you know, lives in those conditions. we tend to keep buckets, kiddie pools, bird baths

this is the first case of zika in the carolinas. wbtv's pamela escobar spoke with health officials today. and she is live with more. pamela, do we know how this patient contracted the virus? >> yeah, maureen public health officials are saying the person who got the zika virus got it while they were traveling. they are not revealing a ton of information about this person but what we know is that they went to the doctor and the doctor suspect to do could be the virus and made sure the proper testing was done. the zika virus is affecting the virus can cause birth defects so women who are pregnant are encouraged to speak to their doctor before traveling to south america, central america or the carribbean. the person who had zika virus in north carolina traveled to one of those areas. >> we do not have a concern that this one person would cause zika to be spread in north carolina. even if we have a few of the competent mosquitoes you need to have a concentration of people and mosquitoes to sustain transmission. >> the doctor says how we

and for example, men who may have traveled in areas with zika infection or may have had a positive zika test, the cdc is actually recommending now that they use condoms, or obtain from sex, in order to not transmit, despite the fact that we don't know and can't quantify what those risks might be. and for doctors, they're asking doctors and patients to speak to their doctors about this risk. >> paula avila, i'd like to hear from you again because we have been talking about underresources systems, about the areas that the legal system doesn't allow all options, what should be, but is, what the range of full options should be often to women given the reality of life in barrios, in central america, what should couples and what should women who seek to protect themselves and their future children be doing? >> i like a lot of your question it goes to the point that gisele was making that was very, very clear and why, the majority of the recommendations three are given by governments are to women. be and women don't get pregnant on their own. there's a big responsibility also in men to use con

there is no zika vaccine and no antidote. dr. walter tabachnick, an expert on infectious diseases. >> i think we have to take this so seriously that we must do 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. >> i'm 16 weeks pregnant. >> reporter: erica benstock declared her own state of she has canceled her trip next month to cancun, where she was supposed to be matron of honor in her sister's wedding. >> now that it's in the state of florida, how far is it going to spread and what does that mean for everybody who isn't traveling? >> reporter: because you could stay home. >> and still get it. >> reporter: 80% of zika patients show no symptoms. scott, it's likely there are many

it views are differently than zika. what we're starting to see following an outbreak in panama of this disease, there seems to be a household factor. lack of sanitation, for example, appears to be associated with increased risk for having been exposed to this virus. similarly, having particular agriculture exposure. what is interesting in this region, there's been a massive movement of people into the province which was formally forest it, now vast swaths are deforested as they become pasture lands for cattle. and how exactly this will play out, we don't understand yet. we're in the process of figuring that out. i think it is in portland to understand west nile, dengue, and zika all probably originate from the central african forest. contact, ito human is possible that the virus and the mosquitoes ultimately adapt to the human cycles and from there it is able to spread worldwide. again, there are many unknowns in the sequence of eventss, but i think it is prudent to take a look at the ecological effects that may precipi

right now w e the lab does not test for zika. but, they're in the process of sending two blood specimens collected from people right here in iowa to be tested by the c-d-c for the zika virus. that's not to say zika is h he here in iowow but they the iowa department of public health and the c-d-c to further investigate. lab officials say they expect that at some point in the near future they will begin direct testing for zika in this lab because they say the cd-c will likely need some help. "we're not just the onlylyeople in the country that are concerned, there are people all over the country, and there's only one place, the cdc, that tests it right now, so there might be a backlog, i have no idea how many specimens are being submitted to them right now. " the lab here in iowa won't have any role in developing a popoible vaccine for zika. again, they're just making plans and preparing to begin testing for zika in the near future if the c-d-c give them the go ahead. in iowa city, mark carlson, kcrg tv nine news. now here's a look
