there was joy in the heart of everybody that sailed to guernsey on the destroyer bulldog to bring freedom to the channel islands. when a british task force reached the islands on the morning after ve day, surrender was a formality. thousands of german troops were as hungry as the population they governed for five years. the germans were in single file, and they were walking into the landing craft. absolute jubilation. we couldn't believe they were leaving the island at last. the british flag was raised again injersey 75 years on, but this time above a silent square. guernsey's bailiff, the island's civic leader, walked alone to lay a wreath at the island's war memorial. and yet the community spirit which saw the island through occupation is still there, in streets and in gardens. in this street, everybody looks after each other.

we all know each other, so we're just celebrating a very special event together. liberation 75 years on will be remembered, but for very different reasons. robert hall, bbc news, in the channel islands. now it's time for a look at the weather with nick miller. hello. a change to much colder weather is on the way tomorrow, and the cold accentuated by a strengthening wind. it's already windy across northern scotland with some rain. now, overnight, that's going to move its way south across scotland. the back edge seeing a bit of snow to relatively low levels in northern scotland, so it turns frosty and icy here. add some thundery downpours to end the day through parts of wales, pushing into the midlands. still maybe a few heavy downpours in parts of yorkshire, lincolnshire as we start the day tomorrow. still mild for many to the south, but again it's the last night of those sort of overnight temperatures. tomorrow, cloud, some patchy rain pushing southward across england and wales, brightening up for northern england. northern ireland and scotland seeing some sunny spells, some wintry showers in northern scotland. the odd heavy shower towards the south coast of england, maybe thundery towards cornwall

and the channel islands. now, along with that colder air moving south, the winds picking up. gusts 30—a0 mph, stronger than that on north sea coasts and to the english channel later. and that will make a 10—15 degree temperature drop feel even colder than that. hello this is bbc news. the headlines... british airlines call for clarity after plans are announced for a 14—day quarantine for passengers arriving to the uk. ministers pledge to put cycling and walking at the heart of plans in england to reduce the pressure on public transport as lockdown eases. with public transport reverting to a full service, once you take into account the two metre social distancing role, there would only be effective capacity for one in ten passengers in many parts of our

network. navigating a way out of lockdown — how denmark seems to be finding a balance. russia marks the 75th anniversary of the end of world war 2 — but without the planned red square parade of soldiers and veterans. but, belarus holds a full victory parade with huge crowds and no regard for social distancing. and tributes to the pioneer of rock ‘n‘ roll, little richard, who's died at the age of 87. we'll shortly have the film rreview with mark kermode. but first coronavirus: what next? with coronavirus 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, as coronavirus continues to upend billions of lives around the world. i'm annita mcveigh. on today's programme, how testing for the virus differs around the world. we'll also hear from young people across the globe as they try to spread some corona kindness. first, there are still many unanswered questions about covid—i9. one aspect that medics are trying to understand is why it affects people so differently. for many, the symptoms are mild, but for others, the virus is much more serious, and some people struggle to shake off the symptoms for many weeks — leaving them exhausted and anxious. the bbc‘s health correspondent dominic hughes reports. i have suspected coronavirus.

what i was not prepared for wasjust excruciating leg pains. it has been seven weeks now. that feeling of being so diminished and so weak. it came back on week four. in the fifth week of being ill, my partner had to call out a&e. week seven, i relapsed again and had my third wave. for six weeks now, felicity, aged 49 and from london, has been living with suspected coronavirus. david, 42, and living in bristol, has also spent almost two months suffering relapses. this is where i have all my stuff. i make sure i'm keeping cutlery and bowls separate. david's world has shrunk to this room, self isolating to protect his wife and baby daughter. eating and sleeping here, separate from my wife for the last seven weeks. it's hard work. butjust when he thought he was getting better, he'd relapse and he's not alone.

just knowing that people like me, i guess, who have experienced these waves on and off, because when i first relapsed, when it first got worse, it was quite a scary experience, because i thought that you don't know whether that means you are going down, down, down, so it is quite scary to get worse after you thought you were getting better. when i was really ill, i was going on my hands and knees, up and down the stairs. felicity has also struggled to shake off covid—type symptoms and the weeks of illness have taken their toll. this entire experience of being sick and trying to recover has been mentally overwhelming. the hardest part was, having got through the first ten days of being very sick and thinking i was getting better, things later getting much, much worse. i was experiencing such horrific abdominal pains that i wasjust calling out injust extreme agony.

neither felicity nor david have been tested, but both were told by doctors they probably had the virus. they've also been reassured they are no longer infectious, but recovery has been slow. even the slightest uphill slope is a real struggle since being ill. so much about the coronavirus is unknown, including why some experience relatively mild symptoms, lasting a few days, while otherwise healthy people are left struggling for weeks. in many patients with other diseases who are recovering from an acute illness, you do tend to see this kind of waxing and waning effect as you are slowly getting better and you have good days and bad days. there's some evidence to suggest that the prolonged features are the body's response to infection rather than the infection itself persisting in their bodies. the first week, i started to keep a diary of the symptoms i was experiencing. david and felicity hope they are now finally recovering. a return to normalfamily life.

my wife would bring my daughter to the window. it was lovely. i'm going to give you squidgies soon! some of the people there who have been living with suspected coronavirus. but countries across the road are approaching testing for the virus differently. reality check‘s chris morris breaks on what testing is and why it matters. to beat the coronavirus, we have to know how many people are becoming infected — where, when and how. that's why testing for the virus is one of the most important things we can do. it can tell us who might be infected with the virus, who might have been infected in the past and who might need to be in stricter isolation to stop the virus spreading. there are two types of tests. the first type — usually a nasal swab — tests for the presence of the virus, to find out if you're infected right now even if you're not displaying any symptoms and you're feeling perfectly well. if you are infected, you can be isolated and treated if necessary, and people you've been in contact

with can be traced and tested as well. that way, we can stop covid—i9 from spreading so fast. countries like south korea and germany tested lots of people early on in the pandemic and they seem to have been the most successful in keeping their death rates relatively low. other countries, including the uk, are scrambling to catch up. but you need to be able to get hold of the right chemicals, have the right expertise and make sure you have enough laboratories to be able to process tens of thousands of tests every day. the second type of test looks at whether you've been infected in the past and whether you might now have some immunity. it does this by searching for antibodies in the blood, which your immune system uses to fight off bacteria and viruses. sadly, reliable antibody tests are not yet widely available. while they are being trialed in various places and there are some pretty ineffective products on the market, scientists are cautious.

not having a test is better than having a bad test that gives false results. it will be a huge help if a reliable antibody test that can be mass—produced can be developed soon. if we know someone has some immunity, it should be easier for them to get back to work. if we know that lots of people have some immunity, it should be easier for us to start lifting lockdowns in safer and more sustainable ways. but there is a problem. the presence of antibodies may provide some immunity but not necessarily complete immunity. and it's still unclear how long any immunity might last. so testing can help us put other data, like the number of confirmed cases or the number of deaths, into context. but we are going to have to wait some time before a vaccine for covid—i9 provides immunity. until scientists crack that, testing is key to help us deal with this pandemic. across the world, governments are beginning to ease restrictions and reopen society in the wake

of the virus. the decision is based on something called an r number. but what is it? laura foster explains. our lives right now are pretty much controlled by something called r nought, also known as the r number. it tells us how many people will be infected for every one person who has the virus. if the reproductive number is two, one person will make probably two people sick, so it will spread. if it is three, it is around three. without a cure or vaccine, this r number guides every decision governments make. before changes were brought in to reduce the spread, the r number was between two and three. that is why it spread so quickly. the aim is for it to be less than one. speak going to keep it there, so health services can cope.

but r nought is less than one, we can't switch back to how things used to be. each restrictions that is lifted makes the r number rise. some more than others. but it is not clear how much — and how restrictions are lifted will affect the r number too. what happens if schools re—open? what if only some pupils go back? these decisions have to be made for everything and the answers aren't clear. governments need to carefully balance this need to get countries moving while still keeping the public safe. finally, with school cancelled for millions around the globe, some students have decided to use their time to help people, from cooking meals for the homeless and making friendly phone calls to producing personal protective equipment with 3d printers. the bbc has heard from three teenagers about what they're doing to help. it's very important that the young people take part to fight the coronavirus. as a demographic, we are the least vulnerable. i feel the need to do something

to help them as much as i can. i'm i'm13 years old and i'm from malaysia. during the pandemic, i have been helping unfortunate families who lost their income during the restrictions. most of them ran out of money to buy essential food supplies and milk for their babies. i also hope the homeless by cooking food for them and asking my contact to help me distribute the food to the homeless, because i can't go there myself. i have been doing charity work since i was seven years old. i feel the need to do something to help them as much as i can. as a kid, it is the least i can do for now. i'm izzy.

i'm 16 and i live in london. i have been helping to co—ordinate a mutual aid response to support vulnerable people who may not have family or friends who are able to do shopping for them. we get a lot of requests, and it is my responsibility to make sure we get a volunteer assigned as fast as possible. i started doing this because i didn't have school, my exams were cancelled and i knew i had the free time, and i knew it was important for young people to be getting involved, because as a demographic, we are the least vulnerable — and we need to be supporting people who are more vulnerable. climate change has got to go! i'm a climate justice activist normally, and so because coronavirus means we can't be on the streets protesting and striking, i wanted to use those skills to help people in my community in the same way. it is important for climate

justice activists that we treat this as a crisis. hi, i'm diego, i'm17 years old, and i'm from chile. i have my bb printers and i make face shields and other products. in chile, many people are taking lockdown and wearing masks. i started to make face shields one month ago and i made 150. with another friend, together, we made 1,000 face shields and 2,000 masks. it is very important that young people take part to fight the coronavirus. because we have the time, the energy and the information, so there is no excuse. guys, please get motivated, let's get creative and we can fight
