Now on bbc news, with outbreaks at different stages around the world, we explore what might happen as restrictions change and people adjust to a new reality. Hello and welcome to the latest in our special programmes on the coronavirus pandemic. Im victoria derbyshire. On todays programme, we hear from Frontline Health workers on theirfears of a second wave of covid i9 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. The threat of a possible second wave puts Frontline Healthcare workers underfurther 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 bbcs clive myrie reports from the royal london in Tower Hamlets in east london, with cameraman David Mcilveen and producer sam piranty. Its in times of crisis we find out who we really are. Ive 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. This guys not going to survive. Yeah. Lets call the family. Im going to take out your tube now. How does that feel . And all the while, one fear looms, another peak of infections to rival the first. Dont be fooled by the gentle pace. Time is twisted here. On the royal London Hospitals 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 thats the way this is going to spread. But if the lockdown completely disappears, then i suspect that the cases willjust rapidly rise again. Then, as our interview ends, hes called away. Ill be two minutes. His two minutes turned into several agonising hours. I see youre working hard to ventilate him, arent you. We had permission from all the patients or their families to film. Krishnas vital signs have worsened. Hes just 55. Hes 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, theres a final roll of the dice. So you guys, lift him up, ill 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, its all they can do. His lungs are just getting worse, theyre more inflamed again. And youve been preparing to talk to his family . Yes, thats right. Just to let you know, have you called the family yet . Sister becky smith, a presence on the covid ward for absent relatives. Imagine this stress for the team multiplied every day for weeks. Now you understand what the peak of the pandemic was like. Sister Carlene Kelly bore witness to those dark days. Ive felt broken on many occasion and i think a lot of my colleagues have, it consumes you. Its what you think about when you go to bed, when you wake up, youre preparing for your next shift, youre relieved that the previous shift is over, youre sad. Its a huge emotional burden and its 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. Thats 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 its hard to find light in the darkness. But youre about to witness what medicine can do. Were 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. Thats it. When a patients ventilator tube is removed. Its a procedure full of expectation and dread. Will it work . Nice big puff again. Hes grimacing as the tube inches up his throat, and finally leaves his chest. Everythings ok, youre 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. As countries around the world consider how and when to ease restrictions, attention is being focused on the best ways to enjoy second third wave of infections. Chris morris from the bbcs Reality Check Team has more. Will there be a second wave of infections . History certainly wa nts second wave of infections . History certainly wants us to be on our guard. As far back as the middle ages, the black death came in waves. So too did later outbreaks of bubonic plague. A century ago, it was spanish flu the devastated populations while exact numbers are ha rd to populations while exact numbers are hard to come by, it is generally of greed at the second wave of the pandemic killed substantially more people than the first. Healthcare systems were not nearly as good as they are now, nor was medical information technology. More recently second outbreaks of dangerous viruses like sars or mers habit largely been avoided, mostly because they were less infectious than covid i9 other big flu pandemics like swine flu have had second wave is what does that mean for us now . For starters, second wave is what does that mean for us now . Forstarters, no second wave is what does that mean for us now . For starters, no two viruses are exact with the same note epidemics of Infectious Diseases behave in prof precisely the same way we know Infectious Diseases spread when people who have the infection come into contact with people who dont. 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. Thats whats known as the reproductive or r r number and keeping it below one is critically important which is why measures such as social distancing in Contact Tracing will be part of our lives for some time to come. We also need to know how long any immunity for covid i9 will last among people who have had it already once and we need to find out whether there is any significant seasonal variation in the way the virus spreads. Experts have warned of the danger of coronavirus re emerging during the winter flu season in coronavirus re emerging during the winterflu season in europe coronavirus re emerging during the winter flu season in europe and the united states, when Health Systems are already under huge pressure. They also are watching closely to see if the virus mutates and become more or less lethal. So there are a host of actors to take into account in trying to plan for a potential second wave. Its not certain that one will happen in the Early Development of a reliable vaccine would be a Game Changing moment. But until then, 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. Its 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. Thats good. Hes volunteered to help find out because part of the answer might lie in his blood. I didnt think there was any left. Once its sealed up, the bloods passed to volunteer ben. His medical research had to go on hold because the virus so hes set up a team that every day carries covid samples to be analysed. Ben, its quite an odd way to interview someone. It is, yes. How did you get involved in this . Id normally be working in the lab on pulmonary hypertension, a rare lung disease, and its quite frustrating because i cant do that so ijust e mailed my colleagues and asked how could i get involved, how could i help. 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 do 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. 260 addenbrookes patients and staff are giving their blood for this research. Some got very sick, some didnt. The key question for scientists, can you see the difference in their blood . Weve found a number of severe abnormalities in patients 260 addenbrookes patients and staff are giving their blood for this research. Some got very sick, some didnt. The key question for scientists, can you see the difference in their blood . Weve 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. What were 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. So thats interesting. You might be able to tell much sooner whos going to get a very sick . Exactly. What we are hoping is that when people develop symptoms that make them suspect they have coded and get their very first test, when tests become more readily available, at that point we might be able to predict who is going to go on to get severe disease, which should allow us severe disease, which should allow us to intervene earlier. By understanding the science of the disease, it is easier to find drugs to fight it. Next, in britain, the lockdown restrictions were introduced on march 23 to try to slow the spread of the virus. Some of these measures have started to be lifted, but others remain in place. Though 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 document a day in their life. Just saw someone taking their parrot for a walk. Bon appetit. Just keep going, just keep swimming. Im just wanting to be with friends again. The start it was very scary. Wanting to be with friends again. The start it was very scarylj wanting to be with friends again. The start it was very scary. I think it is important to be kind to yourself. I didnt know how to cope with it. Straightening my hair, getting ready for work. Early morning breakfast. There still going to work because i am a teacher. We are looking up the children who are vulnerable and who are key worker children, and staying the two metres is really difficult from the children. It doesnt feel natural. Just about to drive to work. 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, ive 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 i am finding myself away more tired nowadays than before. I am on my way back from the post office now. Literally had to wait ten minutes in the longest queue ever. It was very scary, the idea of being a lockdown and then moving University Courses online. Also, the prospect of graduating, it only as a day and i understand that, however, it is a closing chapter and thenit however, it is a closing chapter and then it is done. Yesterday was my la st then it is done. Yesterday was my last exam, but it isjust weird that you are stuck in this weird limbo. So ive checked my work emails, sent a few emails out, it isjust before lunchtime now so this is when i try to get my run in. Something i saw yesterday was an ex professional foot ball yesterday was an ex professional football are saying running is like life. You are the only person doing it and you are the only person knowing if you are going to stop. So in times like this, it is so important to just keep in times like this, it is so important tojust keep going. Just keep swimming. I amjust longing important tojust keep going. Just keep swimming. I am just longing to be with friends again, playing football and basketball, you know. Just doing the usual things back outside. Hi, guys i usually work in a hospital but i am currently isolating, as i have tested covid positive. They were such mild symptoms that i had got them confused for hayfever, my sleeping pattern. So, this is where ive spent a lot of my time, in my bed. Small moments like this, i am just sad that i dont get to share this experience with friends, because this is, as i would like to call. What i have found difficult about being on furlough during lockdown is not having a sense of purpose is contributing to anything which i would normally get from myjob. |j didnt know to cope with it. Socially distancing, from family and friends, it is something i have never done. I wont prepared for it. So weve just gone for a walk. Obviously the rules in wales are a little bit different, so we dont try to leave the house too much. But oii try to leave the house too much. But ona try to leave the house too much. But on a day like today when it hasjust been so hot, it is really nice to just get out for a bit. We have not been able to go outside, and with the weather being as good as it has in the last few weeks, we decided to put more effort into making our gardena put more effort into making our garden a nice place to be. Hello. Im on my daily government sanctioned walk. I am the least vulnerable, out with my mom and my brother. They are two other people i am living without the moment. This is my brother luke. What are you missing . College. And i missing friends. So my job is the daily dog walk, which is a dream. I love it. Getting outside has definitely been a morale boost and made me feel a lot that. You know what time it is its eight oclock. Applause. We have kinda formatted our final play this year to be zoom in addition. Zoom edition. Today was the last day of filming but. Thats not enough. It is not live theatre, its not nearly as good, it is not nearly as fun. You dont get thatjoy nearly as good, it is not nearly as fun. You dont get that joy of it. And that is something i miss very, very much. I think have and that is something i miss very, very much. I think i have come to really appreciate lockdown. Some gifts but i have made from unique mates. Making salad are right now, but im sure everybody else in the country is doing as well. Im lucky enough to have a support network around me. No, i cant taste anything yet. I think Mental Health is so important for everyone every single day. Imjust is so important for everyone every single day. Im just going to finish watching this episode of breaking bad, i think, watching this episode of breaking bad, ithink, and watching this episode of breaking bad, i think, and then had to bed. Yeah. Good night. 14 million tourists visited thailand last year, but because of the coronavirus pandemic, the industry that has collapsed. Among those affected are elephant keepers, who rely on the income they get from relevant experience counts and shows. Keepers and their elephants are now migrating across thailand from the countrys tourist centres to the remote villages where they grew up. The bbcs thailand correspondent joined one group making thejourney home. Hundreds of elephants are on the move in thailand. We are taking the move in thailand. We are taking the Elephants Back home because of covid i9. There are no more tourists. We have been waiting for several months to see if it would get better. But it has not. So she is taking her elephants to her village, where she can feed them. It is more than 100 miles away in the mountains of chiang mai province. It will be a difficultjourney. Mountains of chiang mai province. It will be a difficult journey. We expected to take three days and two nights, but we have a young elephant and an old one. The baby elephant is four months old. If they are tired, they can rest. Elephants are synonymous with tourism in thailand. But it is an industry accused of cruelty. The 3000 elephants that rely on tourism are at risk of starvation. For some elephants, the pandemic has meant more suffering. Translation if it doesnt get better in three months, i will Contact People i know along the myanmar border. I will take my elephant to work in the logging business there. After two days of travel, the convoy is chased out of a village. Locals think beekeepers may have coronavirus. Tired, comedy tea m sto ps may have coronavirus. Tired, comedy team stops at a river to rest. The elephants got very thirsty, and the little one had no energy to walk. Their journey little one had no energy to walk. Theirjourney home has been funded bya theirjourney home has been funded by a local charity owner called ms lek. She thinks this is a chance to transform an industry. 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 would think, and tourists would have time to think too. After three days, travelling, beekeepers and their elephants have arrived safely. And they are having a buffalo right now that the villagers prepared for them to welcome them home. Thats 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 again. Sunday was another very warm day nationwide, and capping off a very sunny weekend was a beautiful sunset to end the day in the herefordshire area. The top temperature was 28 degrees in porthmadog, making it waless hottest day of the year so far, and only three tenths from the highest temperature weve seen in the uk this year. At the moment weve got clear, starry skies out and about. A few mist and fog patches possible later on across coastal parts of scotland and north east england, but probably not too many of these. Temperatures first thing, eight to 13 degrees in towns and cities and cooler than that in the countryside first thing, but what you will notice early on monday is weve got plenty of sunshine. Into the afternoon, a bit of fair weather cloud popping up into the sky, so some sunny spells, the cloud not spoiling the sunshine at all, really, and another day when we will see the temperatures climbing widely into the low to mid 20s, probably peaking at around 27 celsius in some western areas. 50 more very warm and sunny weather on the way for monday. Looking at the weather charts for tuesday now, we have something of a change on the way. That change, as this cold front approaches northern scotland, bringing some thicker cloud here, and yes, outbreaks of rain on the way. I know some of you have wanted rain for a while. That rain will be accompanied by cool northerly winds, so temperatures for northern scotland significantly lower on tuesday with highs of 13 in stornoway. For Northern Ireland, southern scotland, england and wales, this is the last of the very warm days and plenty of sunshine again with temperatures widely low to mid 20s, but into the middle part of the week, its set to turn much cooler, and there is the prospect of seeing some rain. On wednesday, weve got a trough crossing the uk, bringing a mixture of rain and showers. As that moves through, the northerly winds that follow will be dragging on some much cooler air as we enter the week, so temperatures progressively will be dropping. Many areas will see outbreaks of rain. Closest to that area of low pressure the rain will be heaviest across parts of northern scotland, maybe Northern Ireland too. The amount of rain we see further south will vary from place to place but most places will see some rain towards the end of the week.
