This one is four stories high and it was meant to send a message to the World Leaders meeting at the Nuclear Security summit. Demonstrators inflated this giant balloon shaped like a missile in mcpherson square. The group global zero is calling on all countrie arsenals. An estimated 15,000 warheads exist worldwide. Russia and the United States possess about 90 of them. The leaders of 50 countries are huddling at the Convention Center trying to figure out how to keep Nuclear Weapons out of the hands of trifererrorists. President obama said the world has measurably reduced the risk of terrorism. He particularly praised argentina, uzbekistan and switzerland for eliminating their stockpiles but he acknowledged the Islamic State has already used chemical weapons and al qaeda is trying to get his hands on nuclear material. There is no doubt that if these mad men ever got their hands on a nuclear bomb or nuclear material, they must certainly would use it to kill as many innocent people as possible. President obama also met with the leaders from the six nations that helped negotiate that Historic Nuclear Deal with iran. Going to show you a live look at the white house now. Marijuana activists are planning to gather across the street from the white house in Freedom Plaza tomorrow and then theyre going to light up. Recreational marijuana use is legal in the district, but smoking marijuana in public is not. The demonstrators say they expect to be arrested. The group that helped to get the legalization of pot on the ballot last year is behind the protest. The laws arent uniform across the country. Protesters want the president to change that before he leaves office. We thought we were getting change. If he wants us to come out and vote for the democratic nominee, which im sure he does, he needs to do this now. The Freedom Plaza demonstration starts at 2 00 tomorrow. Tonight, an urgent warning from scientists. Zika has the potential to spread across the country this mosquito season. Doreen gents lzler is with us bath right here in prince georges county. Im Tracee Wilkins. Coming up on news4, im going to take you for a tour of the largest Muslim Center in the weern hemisphere. St but jamie raskin is the only democrat for congress whos authored landmark progressive laws marriage equality, equal pay for women, green maryland act, assault weapons ban, and more. Raskin im jamie raskin, and i approve this message. Developing right now at 5 00, hundreds of doctors, scientists and mosquito experts gathering for a summit at the cdc. Theyre concerned about the potential for the zika virus to spread throughout the country and they are focused on pregnant women. Theres growing evidence zika can cross the placenta of an infected pregnant woman invading the brain of the developing fetus causing severe birth defects. If we wait until we see widespread transmission in the United States, if we wait until the public is panicking because theyre seeing babies born with birth defects in every state or across the country, we have waited too long. State and local Health Officials are working to identify areas to spray the insectici insecticide. They also want to educate women who may get pregnant about the best ways to avoid infections. There are 200,000 cases now of the zika virus across the americas. It was a local case news this week and Doreen Gentzler joins us with what doctors are learning from it. The woman contracted the virus while she was 11 weeks present. She was in central america. She came back home to the u. S. And developed the zika virus symptom. Her pregnancy was monitored very carefully and her ultrasound at 19 weeks showed significant abnormalities. At 21 weeks she terminated the pregnancy when it was clear from the scans that the fetus brain was developing abnormally. Today i got to interview the doctor who treated her. Shes the medical director of sibley memorial hospitals maternal fetal medicine division. She showed me the ash normalities and you can see them in these pictures of the ultrasound at 19 weeks. Whats really surprising is all the previous ultrasound in this carefully monitored pregnancy had showed nothing wrong and that gave the mother a false reassurance but it gave the doctor and other researchers trying to figure out the zika virus a much better understanding of the virus. You know, we are getting new information about the zika virus every day, but there are still so many unanswered questions. Consider that the doctor is one of thousands of ob gnys across the country in the position of trying to figure out how to advise their patients of child bearing age about how long to wait before getting pregnant. There are still so many questions and more coming up on news4 at 6 00 about exactly two pretty significant new find frtion thfindings from this local case. They think the brain was okay and then the virus passed through the placenta and then it turned up later in the pregnancy. Yes. But it was, i think, somewhat surprising to determine how long it took for the virus the damage caused by the virus to show up in that placenta. Also very interesting about this case, you know, theyre looking at cases in brazil, central america, the caribbean. In this case you had a very educated patient who was very interested in sharing information with the medical opportunity. So its kind of unprecedented the amount of data that they got from this local case and how carefully they were able to study the pregnancy and also the fee muss. Very critical and possibly very frightening information from this case. The more we know about it, the more we can understand how to prevent it. Thank you, doreen.
