Joining us from Heathrow Airport for us. The u. S. Moving forward with these travel restrictions tomorrow starting at midnight. What more are you able to tell us and what does this mean . Reporter so lets break this down into whos affected and whos not. First of all its the country affected these are the European Union and norway, et cetera, switzerland countries that share an open border between each other but not the United Kingdom and not ireland. In terms of passengers who are affected, well, u. S. Citizens will still be able to return to the United States from the shengen area and as indeed green card holders, spouses and et cetera, et cetera. Its a complicated list. Thereafter it gets very difficult for foreigners, for nonu. S. Citizens or green cold holders to fly from the rest of europe, if you like, to the United States. Thats why weve seen over the last 12 hours or so many u. S. Airlines dramatically, dramatically cutting flights from the rest of europe. United lufthansa has been cutting flights, all of them because theres simply not been the demand. Those flights over the next few days that are available are just jampacked. And one final thought, flying from london to the United States next week or thereafter the price has rocketed because this is the best way back to the states, except, of course, if youve been in the rest of europe. Lets be clear, if youre a british citizen or if you live in france or you live in germany and you fly to london, can you fly to the United States and get in . Reporter well, no, you cant. You cannot use london as a back door because the promulgation of the regulation says if you have been in the shengan countries. So someone who thinks ill get the euro star from paris to london and ill hop on a plane back to the states is going to be met at the other side well, first of all they will be screen ear, have you been. Now, we dont exactly what information sharing there is, but you will risk making an error, telling a false statement to immigration, and as you know that has serious consequences and ramifications. One final point or one other point is from the rest of europe those aircraft will be going to special designated airports that have been handling, for example, china. Theyre all the usual suspects, chicago, los angeles, san francisco. So there wont be the same capacity across the atlantic. I want to put this in perspective, by the way. The aviation and airline organization, it says there are 200,000 flights between shengen and the u. S. Every year. Its 46 billion sorry, 26 billion worth of business now very seriously in trouble. You may have said this but i want to be clear. So u. S. Citizens currently in the u. K. Or europe, rather, who are flying back to it states theyre allowed to come back, but what is the process like . Will there be a mandatory quarantine for them or what happens . That is unclear. Very unclear. So the nonu. S. Dont even get on the plane. Okay, they are barred. The u. S. Will go to these special airports and will follow, sanjay, the same procedures as was introduced for china, italy and others. But it is unclear at least from my understanding of the rules at the moment exactly whether they are required to go immediately into selfisolation or whether theres going to be some other form of isolation, or whether its sort of a hodgepodge have you got symptoms. So u. S. And by that i mean green card holders and spouses and the like, the aspect of everybody else its a nogo from europe. And if you do fly its a mess. Theres no getting over it. Were talking about millions of people that would normally make this trip. Were talking about the two continents being completely cut off to some extent by sheer confusion. And european governments are seething, absolutely blisteringly seething. First of all they say the situation doesnt merit it and, secondly, they werent even consulted. And as you said those flights that are continuing to the United States are going to be jampacked. So anybody who may you know, the last thing you want to is to be squeezed in coach next to three other people at a time like this. Theres no question look, it comes in tonight. Youve got 12 hours, 24 hours or whatever. The planes start flying here. Its 3 00 in the morning here. The planes start flying in about 3 hours. Same in europe and on the continent as we say. They will be packed as of midnight on friday. The curtain comes down, the number of flights will be cut. And if you really want to see the economic damage, norwegian which is a low cost carrier youll be well familiar with in the United States as well, is slashing 40 of its routes and says it will layoff or could layoff up to 50 of its staff. So the Airline Industry is on its knees as a result of all of this. Wow. Im still trying to figure out what a nifty little weave is, but thats for another time, richard. Now to south korea where weve seen testing and success in flattening the curve. A week ago that rose to 5,700 cases, 35 deaths. This week nearly 7,900 cases and 66 people died. Joining us now from seoul, cnns paula hancocks. What measures are in place rights now . What is daily lifelike for people . Reporter well, anderson, testing really has been key here in south korea. Since this started theres been almost a quarter of a Million People in this country that have been tested. And thats far more than most other countries around the world. And what they are starting to see is that over the last week the number of new cases every day has been decreasing. They still have new cases, but it does appear at least at this point to be some kind of a slow down. I spoke to the Health Minister earlier this week, and he said he was hoping that we have seen the peak. And i also asked him because south korea has been dealing with this for months now. What was the advice to give to the u. S. , to give to europe, to those countries who are now starting to have to grapple with this. And he said test it, Early Detection is absolutely vital when it comes to trying stoostem the spread of this virus, to trying to calm down some regional outbreaks and clusters, which south korea has had an issue with. And also he said its important to try and allocate the medical resources correctly. Not Everybody Needs hospitalization. In fact, in south korea only 10 of those who tested positive actually stayed in hospital at all. So he said that was key as well. But he kept coming back to the fact that you need that Early Detection, and you need more testing. I think south korea, paula, has been sort of held up as a model as far as testing goes. But im curious, what had been some of the other challenges to the response . Well, certainly one of the issues that south korea has is the clusters that have come really seemingly from nowhere in the southeast of the country. There was a Massive Cluster linked to one particular religious group. Close to 60 of cases at one point were linked directly to that one religious group. And officials have questioned that religious group, have said theyve hampered the effort, the fact they were being secretive, werent giving the lists of their members openly. And theres been more than 100 people in a call center that have tested positive, but what officials have done is they have shutdown the building, quarantined everyone, and theyre testing everyone within the building to try and stem that and doing the contact testing. What it does show is no matter how efficient a Health System in a country, no matter how quick the government is to react, it is key that citizens are honest and cooperating, otherwise all the best intentions of a Health System can be undermined here as they were in south korea. Looking a lot of questions on her facebook wall. Hunter lee asked how many people have the virus in america . The answer we dont. We dont. And the projection is it could be 5 to 10, 20 times higher. We just dont know. Joining us from switzerland, the Health Organizations technical lead for coronavirus response. Doctor, thanks so much for being with us. Just globally speaking where do things stand in your view from containing this virus . It seems numbers coming out of china seemed to have stabilized. Do you believe thats true . What have you seen globally . So thanks for having me again. Yes, so what were seeing globally is in general were seeing a decrease in cases across ags sia. And thats led by a decrease in china as youve seen. The reason we believe that is real is because there is a lot of testing happening in china. Not only among cases and contacts but also looking in their respiratory disease surveillance systems, and so its declining in wuhan, in the epicenter of this outbreak. In hubei itself, and i think yesterday there were only 26 cases reported in china overall. But were also seeing a decrease in korea as youve just heard from your correspondent, and weve seen decreases in singapore. The worrying trend now are increases in europe. We are seeing large increases in a number of countries across europe, and that is definitely a worry. But as you know the more you test, the more youre going to find. So it is very important that testing continues and that all cases and contacts are tested. Doctor, theres its a new world i think for lot of people understanding how best to sort of slow the spread of this virus. And something your organization has said is all countries must strike this balance between protecting health, minimizing economic and social disruption and respecting human rights. So what work do you think still needs to be done to really strike that balance . So thanks for that question. We feel very strongly that what has been demonstrated in a number of countries of reducing transmission can be done elsewhere. And what that means is ensuring that aggressive theres an aggressive and a comprehensive approach by all people, by governments that really attempt to find all cases, find all contacts, care for them. Making sure that they get the right standard of care either in hospital. And as you know not everybody will require hospitalization. Some people will develop severe disease, and its important they get the right care. But then making sure that contacts are isolated are in quarantine so that we remove them from other people so that they dont pass that onwards. But if you do that you have to make sure theyre cared for as well, that they have the right information, that they have food, medical care, that they can still reach their love ones. So there is a balance between separating people, you know, making sure we dont pass the virus between people but also making them feel connected with their loved ones. Its interesting. Youve been obviously monitoring this longer than a lot of folks have. Its been on the world Health Organizations radar obviously since what happened in china. You know best case practices, you know what works to contain this. What is the u. S. Not doing that we should be doing, whether its communities, leaders, whatever the case may be . We heard from our correspondent in china who were saying folks in wuhan see in the u. S. Folks in new york still going to gyms and cant believe people are still doing that. What should the u. S. Be doing were not doing right now or that we need to ramp up more . Well, what i can tell you is what we know works. And what we know works is finding cases, finding contacts. We know social distancing works, keeping people separated from one another. We know if youre sick, if youre feeling unwell you stay home. Thats really key. We know restricting your own movement. We know if you can work from homework from home. We have seen in several countries where they have shutdown gyms, they have shutdown social gatherings. And that does work, but its important for everyone to know that it is going to be difficult for some time, that there are measures that need to be put in place, but these measures are temporary. You know, all these measures that have been put in place may seem aggressive and over the top, but we know if you can separate people, then you restrict the possibility of this virus from passing from one person to another. We know that activating your Emergency Response and activating your emergency mechanisms, making sure that governments not only from the health side but that youre working with the finance side, youre working with the travel and tourism industry, youre working with businesses. This is an all societal approach. This is an all government approach. And the last thing we know works is mobilizing your public. So making sure every Single Person knows what their responsibility is. Making sure every Single Person knows that the signs and symptoms are fever and dry cough. Its not a runny nose. You know, there are things that people need to know. What is my individual risk . What are the things i need to do to protect myself and my family . And if you have that, then you have an entire population that can fight this virus. Doctor, we just got a pretty clear description of what this travel ban looks like now from europe to the United States. Is that going to work . Is that an effective strategy, do you think . Well, i just heard about this yesterday, and we know there are many countries that are putting in travel bans. What we know this virus is circulating. This virus has been identified on all continents, and so having what we know will work is not necessarily stopping flights because this virus has already circulated. What we know works is testing. We know you have to be aggressive in finding your cases and contacts wherever they they be. So making sure your Testing Capacity has increased, making sure that the people that do need to be tested are, thats what works. The other thing thats going to work and going to help people and save lives are readying your hospitals. So if hospitals are not ready, they going to be very quickly overwhelmed. And its important that hospitals have the right supplies, that Health Care Workers are trained in Infection Prevention and control measures. Theyre trained in what they can do to help patients who come in. Making sure that you have enough of a work force so that people arent working too long hours. That they, Health Care Workers themselves get a break. These are the types of things that governments, all countries should be doing. Ready your health care system, get your supplies ready, increase your testing, train your Health Care Workers. Weve got a lot of questions from viewers all over the globe. This is video from joseph cook in sacramento who has a question. Joseph . A Research Paper was recently published by chinese researchers that indicated that there are two types of the coronavirus. A type l and a type s. With the s type being the ancestral strain that is much less aggressive than the l type of coronavirus. I was wondering what are the implications of that . Doctor . So, yes, so theres a large number of virologists all over the world looking at these viruses that are identified in Different Countries. Very early on we know there are different groupings of these viruses, and that was just mentioned in the question. There are no indications there are differences in terms of illness in terms of those groupings. This is virus and there are normal changes that happen in a virus over time, but this virus is relatively stable. So far theres no difference in the groupings as it relates to severity. Weve got a question from edward in england. He writes how many people worldwide have actually recovered from the coronavirus . Well, thats a very good question. I dont know the i dont have the exact answer on that. I do know in china that its more than 60,000 people who have recovered. Its probably even higher than that. I think that number was from a few days ago. But thats a good point. So everyone that is infected in this virus not everyone infected with this virus will have a severe disease. What we understand from the data coming from china is about 80 of people overall will have a mild form of this disease. Theyll feel unwell for some time, for a week or two. But about 20 of people that get infected will require some advanced care in hospital. Theyll need to respiratory support. And then a small proportion of people will die. But so far were trying to keep track of the numbers of recoveries globally. We need to follow people through the course of their disease and follow them after they recover to make sure theyre still doing well. At least 60,000 people have recovered. One of the things is worth drilling down a little bit 80 we hear will have mild disease, doctor. But when i read these studies out of china i want to be clear what mild disease means. Because when i read the studies it looked like people in that 80 still could have pneumonia, lung scarring, significant things. Youre right. Its not just, you know, a few days at home feeling unwell. About 40 of people will have a relatively mild disease, and they will feel unwell. Have a fever, respiratory symptoms, aches and pains, maybe a headache. But then there are another 40 that will develop pneumonia or a mild form of pneumonia, and i go that doesnt sound very mild, but will not require oxygen, will not require respiratory support. This is a video question sent from facebook from carol. Lets take a look. Ive had cancer, and i wonder if theres anything specifically Cancer Patients should be watching for and if we should check for our doctors earlier. I did hear that clearly. I dont know what her age is but i would say elderly late 60s, early 70s perhaps and she said she has cancer. So, yes, we do know there are individuals who are more at risk for severe disease and death. And these are individuals who have underlying conditions such as cancer. Such as cardiovascular disease and because of their underlying conditions are more likely to develop a severe illness and die. So it is porn that people who do have those underlying conditions do talk to their doctors. Especially if theyre older, if theyre above the age of 60, 70, 80 years old. Speak to your doctor. Talk to them ab
