hello and welcome to the latest in our special programmes on the coronavirus pandemic. i'm victoria derbyshire. on today's programme, we hear from frontline health workers on their fears of a second wave of covid—19 infections. plus, how a team of scientists is trying to work out why coronavirus affects different people in such extreme ways. and, you can always keep up—to—date with the latest information about the pandemic on our website. first, the world health organization has warned of a second peak of coronavirus cases if lockdown restrictions around the world are lifted too soon. restrictions around the world the threat of a possible second wave puts frontline healthcare workers under further pressure in many countries. the bbc has been given unprecedented

access to one hospital in a community in the heart of london who have been coping with the pandemic, to hear their fears about the possibility of a second wave. the bbc‘s clive myrie reports from the royal london in tower hamlets in east london, with cameraman david mcilveen and producer sam piranty. it's in times of crisis we find out who we really are. i've felt broken on many occasion and i think a lot of my colleagues have. when souls are laid bare. in this time of coronavirus, one hospital and one community reflect on these troubled times. coming upforairto reveal their souls to us. we saw the fragility of life.

i'm going to take out your tube now. we saw its strength. gasping for air. how does that feel? and all the while, one fear looms, another peak of infections to rival the first. we were 20 beds away from being overrun. don't be fooled by the gentle pace... time is twisted here. on the royal london hospital's coronavirus wards, while many patients inhabit ventilated worlds, of slow motion dreams and hallucinations, the doctors and nurses charged with bringing them back to life inhabit the real world where time moves too quickly, as this cruel disease eats away at human lungs with frightening speed. can we just do a couple more suctions?

but the medical staff, including consultant pj zolfaghari, have their own nightmares. are you expecting a second wave? yes, i mean, i have to say yes because i think once the lockdown is relaxed, people of course are going to have more contact with each other, so that's the way this is going to spread. but if the lockdown completely disappears, then i suspect that the cases willjust rapidly rise again. we have learned about during this last few weeks are last couple of months. not perfect but i think we are better placed right now. then, as our interview ends, he's called away. his two minutes turned into several agonising hours. i see you're working hard to ventilate him, aren't you. we had permission from all the patients or their families to film. krishna's vital signs have worsened.

he's just 55. he's going to cause a bit of a problem here... and again... go, go, go, go, go, go. the professionalism of the team is stunning, years of experience are gathered around this bed, as the duality of time, the drifting oblivious patient and the rush to save his life, merge into a tableau for our times. alert sounds so, there's a final roll of the dice. so you guys, lift him up, i'll push the pillows down. ready? this is a last resort, maybe by turning him onto his front they can force air into his lungs, oxygen into his body, it's all they can do. his lungs are just getting worse,

they're more inflamed again. and you've been preparing to talk to his family? yes, that's right. just to let you know, have you called the family yet? sister becky smith, a presence on the covid ward for absent relatives. their eyes and ears. imagine this stress for the team multiplied every day for weeks. now you understand what the peak of the pandemic was like. you all right? faces a little bit moist. sister carleen kelly bore witness to those dark days. i've felt broken on many occasion and i think a lot of my colleagues have, it consumes you. it's what you think about when you go to bed,

when you wake up, you're preparing for your next shift, you're relieved that the previous shift is over, you're sad. it's a huge emotional burden and it's the time of our lives that we will never, ever forget. the peak almost broke minds and according to consultant nick bunker, almost broke the royal london. in normal times we manage about 44 patients. at the peak we were managing just shy of 90 patients. almost double. we were 20 beds away from being overrun. we were keeping people alive. from being overrun. that's what our goal of care was, keep as many people alive as long as we can until we can get back to being able to deliver the quality of care that we always aspire to deliver. sometimes it's hard to find light in the darkness. but you're about to witness

what medicine can do. we're going to take out your tube now. this is one of the defining moments in an intensive care unit. give me a big puff, big puff. that's it. when a patient‘s ventilator tube is removed. it's a procedure full of expectation and dread. will it work? nice big puff again. he's grimacing as the tube inches up his throat, and finally leaves his chest. everything's ok, you're at the royal london hospital. the heavy breathing of a man given a second chance.

but there are other defeats. sadly, that evening, krishna died. another soul, lost. clive myrie with that special report. as countries considering the world how to ease restrictions, the attention is being focused on the best ways to avoid a second or even third wave of covid—i9 infections was a chris morris from the bbc‘s reality check team has more. with a bs second wave of covid—i9 infections? history warns us to be on ourguard. as infections? history warns us to be on our guard. as far back as the middle ages, the black death came in waves. so too did the later outbreaks of bubonic play. one century ago it was a spanish flu that devastated populations and while exact numbers are hard to come by, it is generally agreed that the second wave of the pandemic killed substantially more people than the

first. health care systems were of course not nearly as good as they are now nor was medical or information technology. more recently second outbreaks of dangerous viruses like sars or mers have by and large been avoided partly because they were less infections than covid—i9. but other big flu pandemics like the swine flu have had second waves. so what does that mean for us now? for starters, no two viruses are exactly the same and no epidemics of infectious diseases behave in precisely the same way but we know infectious diseases spread when people who have the infection come into contact with people who don't. an outbreak will continue to grow as long as the average number of people infected by average number of people infected by a person with the virus is greater than one facet that is what is known as the reproductive or r number and keeping it below one is a critically important which is why measures such

as social distancing, contact tracing will be part of all our lives for some time to come. we also need to know more about how long any immunity for covid—i9 might west amongst people who have already had it once and we need to find out whether there is any significant seasonal variation in the way the virus spreads. experts have warned that the danger of coronavirus re—emerging during the winter flu season in europe and the united states when health systems are already under huge pressure. there also watching closely see if the virus mutates to become more or less lethal. there are a host of factors to ta ke lethal. there are a host of factors to take into account when trying to plan for a potential second wave. it is not certain that one will happen and the early development of a revival vaccine would be a game changing moment. but until then, revival vaccine would be a game changing moment. but untilthen, if m ista kes changing moment. but untilthen, if mistakes are made when changing control measures, the virus could spread rapidly all over again. as scientists and governments race

to stop a second outbreak, one of the key questions being asked by medics is why some people get more severe symptoms than others. it's hoped some of the answers might lie in research being carried out by a team of scientists, clinicians and volunteers in cambridge. richard westcott has this. why does covid—i9 put some people like george gilbert here in hospital, yet others get no symptoms at all? how are you doing? lovely. that's good. he's volunteered to help find out because part of the answer might lie in his blood. i didn't think there was any left. once it's sealed up, the blood's passed to volunteer ben. his medical research had to go on hold because of the virus so he's set up a team that every day carries covid samples to be analysed. ben, it's quite an odd way to interview someone. it is, yes. how did you get involved in this? i'd normally be working in the lab on pulmonary hypertension, a rare lung disease,

and it's quite frustrating because i can't do that so ijust e—mailed my colleagues and asked how could i get involved, how could i help? and it has been excellent to be honest because you do feel you are making a difference in these difficult times. samples are taken to a brand—new lab just around the count corner on the cambridge biomedical campus. your blood contains cells that play a key role in fighting off the coronavirus. some of them make antibodies, others directly kill infected cells, but to analyse them, first you have to separate them off. at the very bottom, we have the red blood cells that are the heaviest and go to the bottom of the tube. at the top, the plasma, the solution your blood flows in normally. then we are looking at these white small band, that is the white blood cells fighting off your infection. then it gets more complex. there are lots more types of white blood cells, playing different roles. so next door, a machine uses lasers to count how many you have

got of each key type. it can then separate millions of them off for more tests. incredibly, each blob here is a droplet of salty water with one cell inside. i think we will find that the pattern of white blood cell numbers is going to give us an answer to why some people recover and some people don't. basically people may have different cell structures and sells to the people who are not very l? very ill people may start off at the different balance of white blood cells or they may end up with a different pattern that doesn't help the recovery. 260 addenbrookes patients and staff are giving their blood for this research. some got very sick, some didn't. the key question for scientists, can you see the difference in their blood? we've found a number of severe abnormalities in patients with advanced covid disease and some

of those point very clearly to potential therapeutics that might impact on that disease. we are also finding that a lot of those abnormalities are visible much more earlier than expected. so you might be able to tell much more sooner who is going to get very, very sick. exactly. what we're hoping is that when people develop symptoms that make them suspect they might have covid and get their very first test, when tests become more readily available, at that point we might be able to predict who might go want to get severe disease. —— who might go on to get the disease. by understanding the science of the disease, it is easier to find drugs to fight it. next in britain but walked down restrictions were introduced on the 23rd of march to try and so the spread of the virus. some of these measures have started to be lifted but others remain in place. that the impact has been felt by everyone young people are one of the demographics hit hardest with traditionally smaller incomes and

living spaces. the bbc asked a group of young people across the uk to document a day in their life. just saw someone taking their parent for a walk. itjust keeps going. i am longing to be with friends again.- the start it was very scary. important decline with yourself. i didn't know how to cope with that. just straightening my hair getting for work. ‘for work. little breakfast. ready for work. little breakfast. still going to work because i am a teacherfor still going to work because i am a teacher for software looking after children who are vulnerable and who are children who are vulnerable and who a re key children who are vulnerable and who are key worker children. staying the 2mm is really difficult for the children, it doesn't feel natural. i am just about to drive to work for some it is quite nice to have a few extra minutes in bed in the morning

because there is absolutely no traffic on the way to work. here we go. in the past i have struggled with depression and anxiety. and the anxiety now is something that is definitely still presenting its challenges in many ways. it is definitely draining and lam finding ways. it is definitely draining and i am finding myself way more tower it -- i am finding myself way more tower it —— tired nowadays than before. i'm on my way back from the post office now, you had to wait ten minutes in the longest queue ever. it was scary the idea of being in lockdown and then doing university courses online and also near graduating, i know it is only a day, but it is like causing a chapter and yesterday was my last exam but it was weird that you are stuck in this weird limbo. i have checked my work e—mails, sent e—mails out, just for

when i'm not so this is where i tried to get my run in. something i saw yesterday was someone saying running is like life. you're the only person doing and you're the only person doing and you're the only person doing and you're the only person knowing if you're going to stop or if you're going to cheat yourself out of it. so in times like this, it is so important tojust keep going. just keep swimming!” this, it is so important tojust keep going. just keep swimming! i am just longing to be with friends again, chilling, playing basketball, doing usual things back outside. hi, guys! i usually work in the hospital. i am currently isolating asi hospital. i am currently isolating as i tested covid positive. it was such that my symptoms that i got them confused for hay fever, weird sleeping patterns. so this is where i spent about of my time in my bed it is moments like this that i am just said that i don't get to share

the extremes with friends because this is what i would like to call garden weather. i have found that being on lockdown, is not having purpose or contributing to anything which i would normally get from a job. i which i would normally get from a job. i did which i would normally get from a job. i did not know how to cope with that, socially distance with family and friends is something i have never done. i wasn't prepared for it. i have gone for a walk, the rules in wales a little bit different, we do not try to leave the house too much. but out today it is nice to get out for a bit. not being able to go outside and with the weather being as good as it has the weather being as good as it has the last few weeks we decided to put a lot more effort in to making our garden a nice place to be. hello i'm on my daily government sanctioned walk. i am the least vulnerable out of my mum and my brother, the two other people i am living with at the moment. this is my brother luke.

what are you missing? college. friends. so my job is to take the dog for a walk which, i love it. getting outside has definitely been a morale boost and made me feel a lot better for some ——. a morale boost and made me feel a lot better for some --. you know what time it is, it is eight o'clock. applause we have formatted our final play the suit to be xoom addition. today was the last day of filming that. i would just shout. it is not live theatre, not nearly as good or fun. you don't get thatjoy of it for some and that is something i miss very much. i have come to really appreciate it lockdown for the week

things. a gift that i've had re ce ntly things. a gift that i've had recently for some making this right fiow. . . recently for some making this right now... i'm lucky enough to have a support network around me for some no, ican't support network around me for some no, i can't taste anything!” support network around me for some no, i can't taste anything! i think it is so important for everyone everything a day for some i will finish watching this episode of breaking bad i think and then head to bed. yeah. good night. 14 million tourists hit visited thailand last year but because of the coronavirus pandemic the industry there has collapse. among those affected are elephant keepers who provide on the income they get from elephant experience camps and shows. keepers send their elephants are now migrating across thailand from the country's tourist centres to the remote villages where they corrupt. the bbc prospect tie correspondent

joined one group making thejourney home for site hundreds of our events are on the move in thailand. translation: we are taking the elephants back home back home because of covid—i9. are taking the elephants back home back home because of covid-19. there are no more tourists. we have been waiting for several months to see if it would get better. but it is not. so, she is taking her elements to her village where she can feed them. it is more than just 100 her village where she can feed them. it is more thanjust100 miles her village where she can feed them. it is more than just 100 miles away in the mountains of the province, it will be a different vehicle journey for some we expect it to take three days into nights. but we have a young elephant and an old one. the baby elephant is a months old. if they are tired, they can rest.

elephants are synonymous with tourism in thailand but it is an industry accused of cruelty. 3000 elephants that write on tourism are at risk of starvation. and for some elephants, the pandemic has meant more suffering. translation: if it doesn't get better in three months, i will contact people i know along the myanmar border. i will ta ke along the myanmar border. i will take my elephant to work in the walking business there. after two days of travel, the convoy is chased out of the village. locals think the keepers may have coronavirus. tired, the team stops at a river to rest. the elephants got very thirsty and it seemed the little one had no energy to walk. there journey home

has been funded by a local charity. she thinks this is a chance to transform the industry for some if there was no pandemic today, elephants would still be in the same state. tourists would be swarming here in thailand. but after covid—19, we will think and tourists will have time to think too. after three days travelling, the keepers and their elephants have arrived safely. and they are having a buffet right now that that that which is prepared for them to welcome them home. that's it for now, you can follow me on twitter or head to the bbc news site for the latest information. thank you so much for watching.

hello there. saturday brought more dry, sunny, and warm weather across the whole of the united kingdom. now, it was a fine end to the day in london and west london did quite well for temperatures. heathrow got up to 26 degrees. but for the most part on saturday, the highest temperatures were across the north and the west of the uk with kinlochewe here in the highlands of scotland, the nation's hotspot with highs of 27. we're going to see similar kind of temperatures for these western areas as we get on into sunday as well. now over the next few hours, most of us are going to keep the clear skies but probably some low cloud and some fog begin to push onto the eastern shores of scotland and although temperatures in the towns and cities between around 8—13 degrees, in the countryside the coldest spots get down to about 3 degrees so it will be quite chilly for some of you to start sunday morning. sunday, well, that low cloud and fog can take the first few hours of the morning to clear away from east scotland. maybe a bit of misting this as well in north—east england. but otherwise, a sunny start to the day and a sunny afternoon. now, the highest temperatures

in scotland probably again to the north—west of the country, the highlands doing ok with highs probably reaching around 25—26 degrees celsius here. you might see another 23 or 24 for westernmost areas of northern ireland. and some of the highest temperatures in england across western areas and wales too. you could see highs locally hitting around 27. now for monday's forecast, the high pressure is still in charge of our weather, so we've got more of that dry weather to come. more of the sunshine as well. temperatures still on the high side for the time of year, looking at highs of 24 in glasgow, 26 or so in cardiff, but from then on we're going to start to see the weather changing somewhat because an area of low pressure is going to start to develop to the north of the uk and move in as we head towards tuesday and wednesday. so, that is going to be bringing some cloudy skies with rain or showers pushing southwards and as well as that, the area is going to be getting cooler. so temperatures will be coming back down close to normal for the time of year and normal isn't something we've seen for quite a long time. so, scotland is going to be cooling

down as you can see, there will be some rain and showers around as well as we go through tuesday and wednesday. perhaps some of the heaviest rain actually working through during tuesday night. further southwards across england and wales, still hanging onto some warm sunshine on tuesday but the change comes really on wednesday with thicker cloud. again, rain or showers working in. that's your latest weather.
