 Hi. I`m Carl Azuz. Thanks for watching this Thursday, April 14th.International health officials don`t know how far the dangerous Zika virus was spread.But with spring bringing warmer temperatures to the northern hemisphere, their concern that the mosquito that carry Zika could bring the virus north of Brazil, the country hit hardest so far.Zika is not threatening to many adults who get it.Most don`t even have symptoms.Those who do may have a few days of a fever, headache or muscle pain.But the unborn babies of pregnant women who get Zika are at risk of microcephaly, a disease that slows brain development and can cause lifelong problems.And officials are now linking Zika to premature birth, as well as eye problems and nervous system diseases in babies.There is no treatment and no cure for Zika.But researchers are racing to develop a vaccine for it, and they could be ready to test one later this year.If everything goes smoothly with that and it`s proven effective, a vaccine could be widely available to the public by 2018.

 
I can tell you, the last time I was here at the CDC emergency operation center was for Ebola.
But this is the place where they`re coordinating the U.S. response to Zika.We`ve got an exclusive look at what`s happening inside. Let`s take a look.Welcome to day 12 of the IMS activation for Zika virus.
 
Every morning, this is the first place CDC Director Tom Frieden will look to get the latest on Zika virus.
 
The board here tells us what`s going on at the glance.We see outbreaks around the world where they`re happening.We also look at the details of our responsible.This is the Zika virus.That`s it, right there.This is what is look like under the electron microscope.
 
Shouldn`t we be scared if Zika or is the emotional part of this with regard to pregnant women and microcephaly sort of making this indiscriminately more-having more impact.
 
Over and over again, the nature deals us the wild cards.In the case of Zika, the real tragedy is them like it`s had a child with microcephaly and we know that that is devastating.And I think that`s what`s driving the concern.This guy, this is a nasty mosquito.
 
Is this the one?
 
This is the one. This is Aedes Aegypti.
 
Is anything good about these guys?
 
The mosquitoes?
 
I mean, would you get rid of them?I mean they cost more death than wars and natural disasters and everything put together.You know, the mosquito kills more people than any other animal on earth.
Did they`ve thoughts about possibly using DDT?
 
The fact is that DDT was widely used 50 years ago and virtually eliminated this mosquito from the Americas but DDT was also widely used in agriculture.They got into the environment then it had serious problems in the environment for many species.It also remains in the body for a long time.So, we`re looking at a safer, more effective ways to kill mosquitoes.If you`re in an area with Zika, there are a lot of things you can do.Wear mosquito repellant. Use long sleeves.Use clothing that has permethrin put into it.All of those things really work and staying inside and screen space and air conditioning space really can drastically reduce your risk of getting a mosquito bite.
