this is bbc news, the headlines: president trump has said more than four million americans have been tested for the coronavirus, and many more testing kits are being made available. the governor of new york says he'll launch an aggressive antibody testing campaign next week, to see how many people have had the virus. the british government says a shipment of 84 tonnes of personal protective equipment, which should already have arrived from turkey, had been delayed till later on monday. more than 16,000 people have now died in the uk from coronavirus—related conditions. in other news: police in canada say a man has shot dead 17 people, in a rural community in nova scotia. reports say one police officer was killed, and that the 51—year—old suspect is also dead, after going on the run for hours.

now on bbc news, the latest information and health advice on coronavirus, including what the symptoms are, and how to self—isolate. presented by victoria derbyshire. hello, and welcome to the special programme. i'm victoria derbyshire. for the next half an hour, we will bring you further information and advice about the coronavirus pandemic. coming up, you might have seen the video from 2015 which has microsoft founder bill gates talking about the possible impact a global pandemic could have on the planet. we will hear his thoughts now about this covid—19 outbreak. and a reminder that you can always keep up—to—date with the latest on the pandemic in your country and around the world on our website. but first, charities in the uk

are warning that almost a quarter of the youth clubs that have been closed in the lockdown may not reopen after the restrictions are lifted. it leaves thousands of youngsters with nowhere to socialise. anna adams has been talking to teenagers and youth workers to see how they're doing. normally, you'd have 30 to 50 young people here after school or in holidays. mervyn kaye is showing me around this youth club in lewisham, south london. it's been closed since the lockdown. in what ways are you having to change the way you work? trying to meet the young people where they are, so we're using tiktok, we are using instagram. we are basically trying to recreate the youth club and adventure playground experience as best we can in a virtual environment. hi! missing you! how are you doing? nicola is a youth worker. she's chatting online with kids who would normally be here. i'm missing you guys! how do you think you'll feel if you're not able to come here for three months? i think lads would start

sneaking out and going out. well, this club is confident it will survive the difficult months ahead, but others across the country are worried about the knock—on effect of coronavirus and the lockdown, and what that will do to the young people who have come to rely on places like this. the national body for youth workers says it is already getting reports of some young people feeling suicidal, and self—harming. we're seeing an awful lot of services closed and not being able to reopen and provide that vital support. there's around a million young people with needs that are just not being supported today. charities say more than 20% of youth services will not survive this crisis. we've covered all those areas yesterday, i think. i think today we will go together and cover the estate. youth workers in north london out looking for some of the teenagers they have lost contact with. for now, the kids are off the streets, but can it stay that way? it's those young people who have been perhaps involved in criminal

activity or, you know, excluded from school, i would be worried about that group. because those young people are not on the social media platforms that many of the other young people with work with are. in suburban st albans, these houses are full of young people trying to keep themselves busy. so what are you missing the most? my girlfriend. yeah, that's been the hardest part so far. i've missed her a lot. i don't know that i would be able to cope with three months, having to stay inside. why? not being able to see my friends, not being able to see my family. it's just... ..lonely. if i were to know how long it would last for, that would be better, mentally. but it is the fact that we don't know, so it is kind of like waiting every day. and that uncertainty is the hardest thing for these teenagers. no—one knows how long this lockdown will last. nationwide lockdown measures in the uk, which have been in place now for more than three weeks, are presenting loads of challenges in all sorts of circumstances. it's been really difficult, though,

for those who have recently left the care system — often estranged from relatives and without support networks. ashleyjohn—baptiste has more. it's very empty, very deserted. haven't seen anyone for a couple of days. and i'm back up to my room. daily life for diana, a 20—year—old care leaver estranged from her parents and stuck in student accommodation. so most people have been picked up by their parents. i'm pretty much stuck here now, so... i'm finding things quite challenging at the moment. since the covid—19lockdown, a lot of students have gone home and i'm still living in halls — that's because i don't have a home to go back to. and the whole of campus is shut and it does feel quite isolating. as someone who grew up in care, i am aware of the unique challenges that care leavers face, so when the uk went into lockdown, i wanted to find out

how they were coping. this bedsit is where 20—year—old casey lives. struggling to afford food, she relies on universal credit. you can see my kitchen. my kitchen that's over there. that tiny bit there. and in there, i have a tiny little bathroom. so that is your whole living space? yep, that is my living room, my bedroom... a lot of care leavers are estranged from their family. that is people's main point of support, their main point of contact. i am self—isolating but i have no—one to support me with that. no—one can go do my shopping for me, no—one can help me if i get ill. you're so alone in it, basically. there is not really any support there at all. according to recent figures, almost half of all care leavers struggle with their mental health in normal times and one in four will have a mental health crisis. experts predict that these figures will get worse. 17—year—old freya lives in supported accommodation. she has had it particularly tough.

so a couple of days after the government announced the lockdown, my local authority moved me from one supported lodging to another with two hours‘ notice. which is obviously, like, a really strange situation to be in. so i've been working the weekend before that with the public, so i could have had the virus and not known, and then i'm moving into a house with total strangers who i've met, like, once. a leading charity is calling on councils to do more. we know that councils are under real pressure at the moment. we would like to see all councils making a real effort to reach out to ca re leavers. we would like to see emergency funding from government to help them with that important work, and also to make emergency cash available for those care leavers who are struggling and really need it. according to the local government association, councils are working hard to make sure that care leaders get the support they need. as tough as things are, these care leavers, like so many others across the nation, are remaining resilient. it feels like everything bad that

could go wrong is going wrong at the minute, but i've just got to keep moving on with it, i suppose. we hear a lot about key workers, those people whose work is essential to keep a country running — usually nurses, police officers — but truck drivers say they, too, should be seen as providing a key service. the bbc‘s matt wareham has been speaking to some truckers to find out where they believe they're not being given the credit they think they deserve. without trucks, this country would stop. hi, i'mjensen, i'm 22. i've been driving a truck forfour years. it's nice to be free on the road but it gets lonely. we're delivering a service to everyone. i can't get services, i can't get any food sometimes. some service stations don't let even let you use the toilet or the shower. if i'm using this service for the night, i have to pay for it. that's not fair, in my opinion.

starting off the day with a cup of tea, about as british as you can get. i have to finish making my cup of tea. there is absolutely nowhere to get any hot food for those drivers that don't have microwaves. absolute ghost town. it's very unhygienic. you do what's called the ‘squaddie wash', where you use some wet wipes, which isn't the best. you'll go out every day and might not come home until the end of the week. a lot of people won't realise it can take its toll. so here we have another garage that won't let us use the toilets or be able to get a hot drink. this isjust my life on a daily basis. i'm sat in trucks at the moment. having my break, because i can't legally not have it. i am currently sat in my cab because the services and that, they're shut.

no difference to what we do day in, day out, every day of the year, but normally, day in and day out, every day of the year, we have facilities to be able to get a cup of tea or coffee, we have no problem getting a shower. we can't get microwavable meals in a lot of places, so we had to get them on a sunday, which was quite difficult trying to get everything on a sunday because the shops were empty again. sojust parking up for the night. tonight i've got a pizza i can literally shove in my microwave. although it's not the best meal, it's not nutritional, it's still going to fill me up at the end the day. i was on facetime to my mate kye the other night. i was eating dinner here while he was eating dinner at home. and it was quite nice to have someone to talk to because throughout the day, i don't really talk a lot. i listen to the radio — radio i obviously — all the time, unless i can't get a signal. it's nice to have people to talk to because it gets very lonely, i've got to admit. i pre—made some meals. we have a choice of bolognese,

bolognese and some more bolognese. i'm quite lucky in the fact that i have a microwave in here. time to get ready for bed. because of the covid—19 situation, the government have relaxed our driving hours and that can take quite a strain because, as a driver, i'm one of the lowest paid careers out there. so now i'm in bed, this is my only time to relax, so it takes its toll on your mental health a bit. morning, guys. microwave just on, boiling hot water for my coffee just there, and then i can go and brush my teeth and get ready for the day. i'm out here working on the frontline, in contact with people still, and i'm still getting paid the same as i would on a normal day. we don't get any extra pay because we're hazardous at work

or anything, so it doesn't seem fair that our facilities are being cut, our money's staying the same, we're working extra hours. at the end of the day, we're all trying to get by. treat drivers with respect. we're delivering a service to everyone. we're delivering products, i'm delivering mainly bulk haulage. all of this helps you because without trucks, this country would stop. the question of how close we are to a vaccine for coronavirus is being asked on an almost daily basis as scientists around the world race to find a way to treat covid—19. five years ago, microsoft founder bill gates warned about a widespread pandemic, but says he was subsequently ignored. he's now promised to help fund factories testing for vaccines. he spoke to the bbc‘s charlie stayt and he started by explaining why he believed there needed to be a global response to this outbreak. the tools that are going to reduce deaths, the drugs, you know, that's a global thing to get those

out, and the thing that will get us back to the world that we had before coronavirus is the vaccine, and getting that out to all 7 billion people. and so, the efforts to test those, to build the factories, to understand, you know, is it safe and ready to go, that's a global problem and, you know, so i'm glad, you know, that people are coming together to find where is the best work and combine that. you know, the factory will be in a different country than the science is in. this is the whole world working on probably the most urgent tool that's ever been needed. can i ask you, in relation to the vaccine — i know that you've donated a sum of money in relation to that — just talk me through how — what do you think are the key elements around developing a successful vaccine?

is it money? is it political will? what do you think are the key elements to that? well, we definitely need to fund the research and the manufacturing and the distribution. the distribution piece for developing countries will be gavi, where the uk has always been super generous on that. the research will need to fund about ten — the ten most promising constructs, because we won't know in advance which one will be prove to be safe and effective. and being effective for older people, whose immune system is weak, is a huge challenge. if you really amp up the vaccine to do that, then you can run into safety issues. so we're going to have to take something that usually takes five or six years and get it done in 18 months. there are — there is an approach called mrna vaccine that people like moderna, curevac and several others have that looks quite promising, but we can't count on that, so we'll back, you know, four or five of those and four or five companies

using a more conventional approach, which unfortunately, the schedule for that probably wouldn't be as quick as this rna programme we've been funding directly and through cepi over the last decade. you'll be aware a lot of people in the uk are asking what is a very simple and straightforward question, which is, when will there be a vaccine? what — how do you see that? well, it's a perfect question, because we want to get back to the life we had before coronavirus. and people are seeing the economic destruction, the psychological stress. you know, this is such an unprecedented, very tough thing to deal with. the — people like myself and tony fauci are saying 18 months. if everything went perfectly, we could do slightly better than that, but there will be a trade—off — we'll have less safety testing than we typically would have, and so, governments will have to decide do they indemnify the companies and say "let's go out

with this" when we just don't have the time to do what we normally do. so 18 months is about what we would expect. we're doing everything we can. we'll write checks for those factories faster than governments can, and they'll come along. it definitely shouldn't be money limited. it should be all the best constructs, full speed ahead, science limited. as i understand it then, from what you're saying, there may seem to be some compromise in the safety measures that would normally be expected to create a vaccine, because time is so crucial? well, of course, if you — if you want to wait and see if a side effect shows up two years later, that takes two years. so whenever you're acting quickly, like during the hiv crisis, they created a quick way

of getting drug approval. there is a trade—off there. in that case, it worked super, super well. and here, we have — we will, i think, be able to get some safety indications, but this is a public good. and so, you know, those trade—offs, the governments working on a cooperative basis will be involved in the decision to say, "hey, the regulator says go ahead, even though you haven't taken the normal time period". do you think world leaders now are listening in a way they didn't out of necessity, bearing in mind — and i know you referenced it before — 2015, you gave one of those ted talks, and if people go back and listen to it now, it was extraordinarily close to what is happening now. you were talking about the real risk of a pandemic across the world. did you feel like you were listened to then? no.

the investments that could have been done so that diagnostics would have been essentially immediately available, drugs in less than half the time, the vaccine in less than half the time, most of those investments were not made. now, cepi is the exception to that, but that's about 5% of what could have been done. now we're scrambling and it's taking us much longer to get these pieces together, even though scientists are doing heroic work. so unlike the defence budget that prepares us for wars, where we simulate the problem and we make sure that we're good at it, this risk, which i viewed as even greater than the risk of war, there was very, very little preparation. very few of these germ games where you try out and say, "0k, how do you build up the icu capacity?" you know, "can you make ventilators? how do you prioritise the diagnostics? " that we're just

figuring out as we go. do you think that — was that, do you think, partly a financial decision? that it wasn't deemed to be worth investing that money in something that maybe other people didn't see as clearly as you? well, it's got to be governments, because there is no private sector incentive for something that's uncertain like this. and even when it happens, you know, you have to charge mostly a break—even price for things that are helping out with a global crisis like this. so people still saw war as something to fund. in the less than 10% of that, that would have been needed for this, you know, peoplejust didn't organise their government to have that — that function. i do think now, because this has been so dramatic, you know, we weren't ready for this pandemic, but i do think we will be ready for the next pandemic. using the new tools of science, that's very, very doable.

do — are you optimistic that now — and obviously, we need to get out of the immediate situation — but there will be a different mindset around the fears around viruses and pandemics? yeah, your speed of reaction is so crucial here, because it grows exponentially. you know, if you're there two months earlier, which some countries jumped on this faster than others, you know, they really were checking to see if there was community spread, they got the diagnostics capacity up quickly, but, you know, we should be able to have diagnostics within a month, we should be able to have therapeutics in more like four months and a vaccine in more than a year if we're on standby with the right factories and the right science, and we should have rehearsed all the shortages, with working together, so a really good system for seeing this early and making sure we jump on it before the curve gets to a meaningful part of the population, that is achievable.

i know you reflected for a moment on this earlier on in the interview, and it is inevitable that here in the uk, we ask our politicians questions about the way they've reacted and, to a degree, it's inevitable that those — that thought process will be something that happens in the future that we look back on. i mean, can you sort of talk us through what you see from what's happened so far? well, the — a big missing piece is that, you know, funding the research for these type of vaccines — you know, actually, ourfoundation is the biggest funder of vaccines for infectious disease. you know, there could have been more. cepi is the one thing that did happen there. and, you know, now the next phase is once we get the cases way down, how much can we open up?

and now there is an opportunity for governments to see what others are doing, to see which ones do run into a rebound of the disease, and really share these deep understandings. you know, like, are young people of the infection chain? you know, so i do think we will deal with this opening—up phase in a more collaborative, data—driven way than the first scramble where, sadly, you know, many governments were slow to react. it's been shown that nature can have a really positive impact on mental welfare, according to various scientific studies, so now charities are finding ways to help vulnerable people connect with nature while stuck indoors. the bbc‘s environment correspondent claire marshall has this. if we just close our eyes and take in some shallow breaths.

imagine we're walking at the edge of a field. this is a visualisation, a virtual walk in the countryside guided by a mental health charity volunteer. there are so many different plants and bushes and trees that come together. being out in nature can have a powerful impact. and it became kind of a lifeline, really. i feel like there was something i could do and there was something valuable and beautiful to notice when i didn't feel there was anything. there are many scientific studies that show the health benefits of being in the natural world. so when we're outside, our blood pressure comes down, our heart rate variability goes up, and that's a good thing. 0ur heart rate comes down and our cortisone levels are reduced, and these are all indicators of reductions in stress. so how to get this on lockdown?

i know some of us don't have gardens... ironically, the therapy now involves embracing screen time. live online, they share fragments of the natural world they can see from their balconies or gardens. my family and i have been in self—isolation for almost two weeks because i've got a nasty cough and it is tough, but we're lucky enough to have a garden. what about people who don't? i was diagnosed with depression and anxiety. and i work for the nhs in east london and then day by day, we started seeing the reality of that. day by day people starting calling in, saying they couldn't make it. vivienne is a nature lover. to cope, she'd normally go to the countryside, but now, even the local parks are packed. what else am i supposed to do to try and pick myself up? yeah, so ijust feel like there's no point in trying. but people like emily are trying to help by giving us an intimate glimpse of the private lives of some

of our most loved animals. the wildlife trusts have set up around 20 webcams across the country. nationally, we've seen 275% increase in the number of visitors who are watching it, compared to this time last year. huge people are tuning in and it's so important right now that people are getting that connection with nature, so they're doing it through digital platforms and online wildlife webcams. it may be some comfort to have a look and see that as human society struggles to cope with the virus, the natural world carries on uninterrupted. and just to let you know that you can keep up—to—date with the latest advice on our website, and you can keep in touch with me on twitter 24/7 at @vicderbyshire. thanks for watching. hello. although monday gets off to a fairly chilly start,

temperatures are going to rebound. garden time by the afternoon. quite pleasant with plenty of sunshine out there, although you'll need to take some shelter from a brisk easterly breeze. and there is a lot of fine, dry weather to come this week. high pressure centred close to scandinavia — its influence being felt across the british isles, blocking any weather systems from coming our way. and these are your starting numbers for monday morning, then. most of us above freezing, but there will be a frost again across parts of highland scotland, but again, those temperatures are going to rebound. and while most are sunny, there is a bit more cloud around the channel islands, perhaps parts of cornwall, the isles of scilly, a shower can't be ruled out but most places will stay dry. this is a brisk easterly wind, though, especially in england and wales, average speeds gust 30—40mph, and it's coming in from quite a chilly north sea at this time of year, where temperatures are around 7—9 degrees. so the air is cooled closer to that temperature, and you'll notice that right along north sea coasts if you are outside here, we're around 10—14 degrees, whereas elsewhere, although there's still a breeze to notice, temperatures will be rising mid—to—high teens

and close to 20 degrees celsius in the warm spots here. now, as we go on through monday night, that breeze stays with us. we're mainly clear, that will prevent much of the uk from seeing a frost again. a frost is possible across parts of scotland. and the rain and showers mayjust pep up towards the channel islands, parts of cornwall, south devon and into to the isles of scilly. uncertainty about who gets what but the potential is there for something wet, anyway, overnight into first thing on tuesday. and then on tuesday, it's for most of us another day of sunshine with an easterly wind and those temperatures contrasting between the north sea coasts and those elsewhere that could see temperatures rising close to 20 degrees celsius. taking a look at the big picture wednesday into thursday. the isobars open up, the winds turn lighter and it looks to be turning warmer as well. in fact, by thursday, some spots will be around the mid—20s. friday into the weekend, temperatures start to come down a few degrees. more cloud around, there is a chance

of seeing some showers. but until then, it's another dry april week to come with plenty of sunshine — a brisk easterly breeze, especially along north sea coasts.

this is bbc news, i'm simon pusey with the latest headlines for viewers in the uk and around the world. president trump says testing for the coronavirus in the us is expanding rapidly as the death toll rises to over 40,000. the uk hospital death toll passes 16,000, as healthcare staff call for more equipment to protect them against coronavirus. we look at the different solutions to different covid—19 problems with our correspondents around the world. how blood from coronavirus survivors could be used in a new treatment for those infected. one other main headline — a guman in a rural community in nova scotia in canada kills at least 13 people.
