All of italy is going on lockdown. Tonight the Prime Minister announcing drastic new measures just a short time ago, essentially telling everyone in his country to stay home. Italy is struggling to contain the largest european outbreak. City streets, stadiums and landmarks usually bustling with life are now eerily empty and quiet. Charlie dagata reports tonight from rome. Reporter dramatic new developments at the sharp end of whats become the worst outbreak outside of china. Prime minister Giuseppe Conte announcing tonight severe restrictions on the entire pe. Ion of around 60 million from tomorrow morning, all sporting events are off, including soccer, the general public should only go to work, and work from home if possible. Public gatherings are out of the question. Heres why government figures tonight continue to soar. More than 9,100 cases, 463 fatalities. Coronavirus contamination is growing in number and spreading in territory. Even before the dramatic move tonight, the World Health Organization had applauded italys extreme step forward.

As for italians, theyre saying dont travel, dont even leave home unless necessary. Essary. Odonnell Significant Development tonight, charlie. Thank you. Because of that we want to bring in our chief medical correspondent, dr. Jon lapook. All right, jon. We just heard about italy in lockdown. Weve seen closures of schools, churches here in the united states. Why is the c. D. C. Using that phrase social distancing, and does it work . Well, its basically figuring out ways to keep us away from each other, and there is evidence that it does work. In the 1918 flu pandemic, cities that adopted it, they had fewer mortality than cities that didnt. So, yes, there is evidence. Course, the flu, which affects millions, kills at least 20,000 people here in the u. S. Every year. So explain why Public Health officials are so concerned about the coronavirus. Well, we are still concerned about the flu. And youre right, it kills a lot of people, but there is a difference. With the flu, we know come spring, rain or shine, it will start to die down. So its predictable that way. And there is a vaccine and there is a treatment like tamiflu. With coronavirus, we dont know what will happen with the warm weather. It may die down, it may not. There is no treatment known, there no vaccine, and unlike the flu where you can have some immunity from past flu seasons, there is no immunity to this new coronavirus. And what that all adds up to is uncertainty, which wall street hates and americans hate. Odonnell and jon, i have to get you to address the issue of these tests. Do we have enough tests . Are people going to be able to get the tests to find out if they have coronavirus . Are we getting near some sort of turning point on that . We all hope so. Its been very frustrating right now without these diagnostic kits. I mean, places like south korea were able to test almost 200,000 people, and here in the united states, we were able to make a diagnosis in places Like Washington state where people ple obvious symptoms, but whats going on in the rest of the country . Is it possible that people have very few symptoms or even no symptoms . Until we have these diagnostic kits, we are not going to get our arms around it. Once we get our arms around it, well have the ability to figure out a better plan for getting it under control odonnell all right. Dr. Jon lapook, always good to have you. Thank you so much.
