Although more than 6500 people have been tested for the coronavirus in the uk, so farjust 13 have tested positive, including the four cases on board the diamond princess cruise ship injapan who have now home. Medical correspondent fergus walsh explains how people can best protect themselves. The new coronavirus spreads through droplets in the air when infected people cough. So, if youre just a few feet from them, you could breathe in the virus. If you touch an infected surface and then rub your eyes or mouth, that can also pass it on. Its why regular hand washing is important. None of us has any immunity to this virus, so if theres a major outbreak, any of us could catch it. But its worth stressing that it causes only a mild respiratory illness in four out of five people, wholl get better without any medical treatment. The symptoms begin with a fever and a dry cough. The older you are, the greater the risk of complications, such as shortness of breath and pneumonia. Especially for those with Underlying Health problems, such as heart and lung disease and diabetes. But the biggest viral threat at present is seasonal flu, which causes thousands of deaths in the uk every year. If we get small, limited outbreaks here, we could see the same sort of quarantine restrictions that are being tried in other countries. School closures are possible, as are the postponing of sporting fixtures and other Public Events anything where large groups of people congregate. But if we get cases popping up all over the country, then locking down communities wont be possible. Instead, the focus will be on getting people to self isolate. The longer we can keep this virus at bay the better because with the warmer weather, theres a chance that cases might start to dwindle. Fergus walsh for us there. Now on bbc news, the travel show. This week on the travel show carmens chilling in northern japan, despite a lack of snow. Wooo im in brazilfor the countdown to carnival. I dont know what im doing and we hit the road in america, with one man and his very devoted dog. This week were kicking off onjapans northern island, hokkaido. Its the countrys winter playground, hosting skiers and snowboarders from everywhere. Its also home to one of the worlds famous winter events the sapporo snow festival. But, sadly, milder temperatures and drier conditions have led to problems for organisers this year. So carmen has pulled on her snow boots and headed north to see how theyre coping. The wide open spaces of hokkaido. At any time of year, people come here to be outdoors, but especially injanuary and february the height of the ski season. The resorts on hokkaido are globally renowned, partly because of the quality of the snow. But also theres a real diversity in the landscape which provides fast black runs, gentle nursery slopes and loads of backcountry off piste skiing. But this year, theres been a problem. Its the lowest snowfall on record injapan since 1961. And at this resort here they had to delay their opening by one month because there just wasnt enough snow. So do you think skiing as a pastime, a winter pastime, might be in danger . All of this is difficult to hear if this is the highlight of your sporting year. But the weathers had an even bigger impact at the bottom of the hill. This is the sapporo snow festival, held every february right in the heart of hokkaidos capital. Laughter wooo uptempo music plays its a big deal and famous internationally. About 2 million visitors come every year. Most people come for the incredible snow sculptures. It started in 1950 as a way for High School Students to publicly display their sculptures, but now its grown into something quite different. Teams come from all over the world to compete and, for me, watching them sweat is just as much fun as seeing the final result. Gosh, this is serious business. Look at this man here, hes even got a sculpture, a mini version. Hi. Whats it going to be . Its going to be the legend of pele the fire. Pele . 0h. The fire goddess on the big island, the volcano killer whale. They say that when the flames would go to the heavens she would do a hula to the gods. Wow her spirit would be inside the fire. So this is the australian entry, and its going to be, eventually, a waratah, is an indigenous bush flower. Because weve had the bushfires over the summer and the flower is like a beacon in the australian bush and its got to regenerate after the fire. So were going do this beautiful flower with a beautiful flower head and its going to regenerate and its an ode to the bushfires from summerand our country, australia. Great. This is our team up on the top. Hi, guys. Hello hi konnichiwa from japan. So how long have you got . Tell me the logistics of the snow festival competition. Theres 11 international teams. But were all, equally, given the same amount of tools and weve got four days. So we work from nine oclock in the morning until nine at night. We can have breaks whenever we want. Basically today were marking out and each day well progressively remove the snow and then start to put the detail and then finish off the beautiful flower of the waratah. So what are conditions like this year compared to last year . Theres a lack of snow this year. Its been reported that the snowfall is 40 days late, they said. Wow. So there should be a lot more snow. And in past years, weve been standing against the sign and the snows been up to the bottom of that sign. So were actually standing. Wow. So were really low. With the good quality snow, its really easy to cut and carve. The snow quality is a bit less than what we would we have, but it is snowing now, which is great. As this years festival opens, the hills around the city were measuring snowfall of about 60cm. Normally its close to a metre. So, where did all the materials come from . Well, a massive logistics operation sprung into action. Thousands of lorries scooped up snow from around the island and brought it into sapporo. Lets hope next year doesnt show a further decline. And, by the way, if youre interested in how the australian entry turned out here it is. The waratah flower symbol of the countrys resilience following those forest fires. And the winners . Well, for the third year in a row, first place went to thailand for this mother and baby sea turtle. Well, if youre still keen to hit the slopes, heres the travel show guide to some places other thanjapan you might want to think about. Two of scandinavias biggest resorts are now much easier to get to. Scandinavian mountains airport opened in december and serves norways biggest resort, trysil and salen in sweden. Salens only a 10 minute drive, but you can also book a transfer by dog sled. The airports served by london, copenhagen and aalborg. If youre in europe and would rather not fly, there are plenty of seasonal train options running to the resorts in austria. Theres another month left on the alpine express, for instance, the sleeper train which runs all the way from the netherlands, through germany, to a number of stations that serve about 100 different resorts. Its one way to shave a substantial amount of the Carbon Footprint of your trip. And if you cant get your act together before the end of the season in the northern hemisphere, theres always copenhill in the danish capital open all year round. Its an artificial slope built onto the side of what they say is the cleanest Waste Energy Power plant in the world. Once youre done with skiing, you can try tobogganing, climbing, or hiking. And if want, you can book ahead you have a peek of the incinerator inside. Still to come on the travel show im getting ready for this years carnival here in rio. And we meet and easy riding duo taking on an incrediblejourney across the usa together. So dont go away. This week were in rio dejaneiro, a city certainly not lacking in colour. Theres graffiti, theres music, but nothing quite prepared me for this. This is the selaron staircase, first created 30 years ago by chilean artistjorge selaron as a way to brighten up his local neighbourhood. There are more than 200 of these kaleidoscopic steps. Its a bit like a giant i spy. Theres photos, little mosaic tiles of princess diana, bob marley, kazakhstan, right in the middle. As its fame grew, people from all over the world contributed tiles to the project. For selaron, it was a cumulation of his lifes work. He died in 2013. His body found at the foot of the stairs. But his creation lives on. Today its a big tourist attraction in a largely safe section of the city. Get here after 10am in the morning and youll probably be jostling for space. This isjorge selarons legacy. Tiles were sent here from all of the world to create it, now tourists come here from all over the world to enjoy it. It really is a special spot here in rio dejaneiro, brazil. Up next, its time for another of our incredible journeys. Michael fiala and his best buddy, a siberian husky called sox, are part way through a truly amazing road trip across america. Their aim is to take on all 50 states and 61 National Parks and, as you can imagine, theyre turning quite a few heads as they do it. We caught up with them as they arrived in florida. My names Michael Fiala and this is my dog, sox, and we are currently travelling all over the country. Were trying to visit every single state and every Single National park in the country all on a motorcycle. This all started when i actually went on a trip abroad and i wasnt able to bring sox with me, and when i got back the greeting that he gave me, it was really heart warming, but it also made me feel kind of bad because i knew that he was really upset that i was gone for so long. So i kind of rearranged my bucket list to do all the things i could do with sox. His safety is my absolute most important thing. I know that my eyes are on the road at all times, that i am fully attentive to whats going on. At this point in time, hes now got almost 3,000 hours on a motorcycle. And so im not concerned with sox falling off, because he knows how to shift his weight, he knows how to hold onto me. Every National Park has blown me away, just the cosmetic beauty of it, looking across a landscape that youve seen nothing that looks like that in your life. Its really impressive. And then of course the fact that every single time im there and im enjoying some sort of view i look down and my dog is doing the exact same thing, hes taking in the experience just as much as i am. My best memories with him was when we were actually in big bend National Park in texas and we were driving on a highway and a deer actually ran across the road. I saw the deer run across and then run into the woods. But when i actually looked back on his go pro you could see that he watched the deer run into view and then traced it as it was running off in the woods. Im enjoying all these moments, but when i look at film like that and see that he was seeing the same thing i was, to me thats really special. I get a lot of people who say, well, you should strap him down so that hes secured to the bike. But its a common misconception. Truly, the safest thing for a motorcyclist is to be able to get away from the bike, so god forbid if anything ever did happen, the best Case Scenario is for us to be away from the motorcycle, away from the accident. Dont go in there buddy, you are going to be cold tonight. Im doing this because theres too many people that say, i wish i did in their life. And i dont want to be one of those people. I want to say i did the things i wanted to do and i dont want to wait until im much older to say, ok, now i can go live life. To me, you dont know how long your life is going to be so you should just live it, and i have to include him, because hes living it too. Sox this weekend, millions of people across brazil are preparing for the worlds Biggest Party carnival. The main celebration in Rio De Janeiro lasts five days, but the action does not stop there. Over 500 parties line the streets of rio during carnival season, and this year youre in luck, because the mayor has more than doubled the celebration, from 23 days to 50. So in 2020, theres plenty of time to join the fun. Carnival began here almost 300 years ago as a ball for the portuguese elite. But since then, its opened up to everyone. Local groups called samba schools prepare all year round for the events, designing floats and costumes and planning epic dance routines. These schools are often located in poor neighbourhoods, which beyond carnival preparations also provide havens for local children, teaching them vital skills to help them later in life. This is you in the photo . Yes its got to be, right . Wait, ah, this one yes, thats me. The smiles the same. King benefited first time from the social outreach provided by her samba school. You know, when you grow up in a favela you dont have of opportunities, so when you get the chance to have an opportunity, you just grab it. So i started at the social project when i was about nine. And then i got a chance to learn english, thats why im communicating with you, because i got a course for free through the social project. So this is the part that most people dont know, the way that people can be part of the samba school. So the party is good, the social idea, its much more important. Patchy public funding means the samba schools have to find clever ways to support themselves. Kings school, grande rio, has turned to tourism. Theyve opened the doors of their workshop to those who want to catch a glimpse of the monumental effort that goes into carnivals centrepiece parade. Along with other ex samba school students, king is now one of the tour guides here. Wow. This is the backstage of the carnival. This is the most fun ive ever seen in a warehouse. I think so. We have actually six floats in here. Only six floats . only six. Inside of this warehouse, only six. I guess i assumeded this was a float, this was a float, that was another float, but theyre the size of city blocks, almost . Yes. Theyll be massive. Yes, yes. You can really see the scale of the operation. The parade is a serious business. The samba schools all compete against each other for a big cash prize. Each school keeps their plans and designs top secret. So much of rio grandes workshop is strictly off limits to tourists. But ive been allowed a rare behind the scenes look. Im having a hard time understanding this. This is all for your parade . It is, this is only for our samba school. All this warehouse, all the costumes are ours. All the welding, the sewing, the machines . Everybodys working on one show, your parade . Yes, everything. We can have about 3,000 costumes, easily. So this is one show out of thousands, because it looks as though these headdresses have five, six, eight, maybe, per headdress. Theres be a hundred headdresses. You know, the last time i did arts and crafts i was probably in grade five. I have not worked with sparkles in a long time. This is the part im good at. Ready . Laughter. 0k. 0k not bad for a first one, eh . You think so . He said its amazing. Its amazing somehow i dont believe him. Grande rio has been running for more than 30 years. The schools current leader, camilla, has grown up with it. We have an Educational Programme called the schools carnival and we have many courses, all through year, for free. When you meet the families and the kids and you understand the passion that they have, why not to get this and transform it for education . Especially in brazil, a place that needs a lot of effort to make peoples lives better. 0k, of course, the parade is amazing in itself and all the kids love it, but all year long, you need something more for these kids. Camillas school of carnival gives these kids hope and three times a week they all come together to rehearse for the highlight of the year the carnival parade. Moments like these are why i travel. I dont exactly know what is going on, but its a rehearsal . Ah, yes, this is the place where we actually do the rehearsal. So as you can see, its an enormous place. We can get involved, apparently i dont know what im doing but maybe thats half the fun. Behind me in this building a whole new generation is finding their best life through drums, dance, and a whole lot of fun. I think if weve learned something today, its that carnival is much more than a party in brazil. Its part of its soul. Well, thats all for this week. But coming up next week im continuing myjourney through south america by heading across the border into argentina to find out how one of the continents most fearsome predators mightjust hold the key to saving some of its most stunning scenery. Oh, my. Guys, this is. When you make eye contact with a beast of this size, your heartjust goes. So make sure not to miss it. But for now, from me, mike corey, and the rest of the travel show team here in beautiful brazil, its goodbye. Hello there. Were moving into colder air more widely across the uk at the moment. Yesterday, of course, we had quite a snowy scene across the northern half of the uk, notjust in scotland but also for Northern England and the hills of northern ireland. Further south there is still flooding, a major concern particularly on the river severn, and there is a lot of rain from this area of cloud here in the hills of wales that will be feeding into the river systems. That cloud brought the snow more recently in the north east of scotland, thats pushing away, and instead we are drawing down colder air. This is proper polar maritime air, the air coming all the way from iceland and greenland, and it will feel colder. There could well be some icy patches around overnight and into the morning, especially across the northern half of the uk. And tuesday will be a day of sunshine and showers. Those winds blowing in some showers almost anywhere really. The more frequent ones will be across the western side of the uk, with some snow over the hills, but therell be some heavy showers, therell be some hail and thunder. It will be quite windy for a while in the far south west of england. And those temperatures will be noticeably lower for england and wales. And a chilly start to wednesday as well. A bit more blue on the chart almost anywhere could have a pinch of frost, particularly in rural areas. It depends where the showers are and the strength of the wind, there will be some showers around first thing. 0nce those fade away, many parts of england and wales, eastern scotland, may well be dry with a fair bit of sunshine around. The showers continuing into the west and the north west in particular. Again, wintry over the hills. Those temperatures arent really changing much on wednesday. Now, during wednesday night, weve got to keep an eye on this system here. That threatens to bring some rain, with a bit of snow to more southern parts of england. That then moves away, weve got a brief ridge of High Pressure coming in, and that means fewer showers following that wetter weather as it clears the south east of england. Some showers coming into the north west, but the winds wont be as strong on thursday noticeably lighter in the south west of england and wales. Therell be some decent spells of sunshine, but again its still quite cold air, so temperatures 6 8 degrees. By the end of the week, things may look a little different. Instead of the cold air coming in on that west to north westerly, the wind direction should change to more of a south westerly wind. Thats milder air, of course, but as weve seen right the way through the winter, it means cloud and outbreaks of rain. Quite a messy picture by friday and perhaps into the weekend as well, with some further rain at times thats likely to lead to some more flooding. Bit of snow over the northern hills, but once again well find the winds picking up. This is bbc news. Welcome if youre watching here in the uk, on pbs in america or around the globe. Im mike embley.
