the risk of getting a downpour with thunder, lightning and hail. with thunder, lightning and hail for any one location is low, many of us will miss the storms. the temperatures today will nudge up to around about the mid 20s and still be hovering in the low 20s and early evening across many parts of the uk. cooler on the north sea coasts. it has been cloudy, gloomy and misty and quite foggy. the forecast for monday, again, a lot of sunshine around. we are expecting further showers to develop across more northern parts of the country, so yorkshire, lancashire, the north—west of england likely to catch some showers and thunderstorms. to the south it should be mostly sunny and warm. hello this is bbc news. the headlines: atlanta's police chief resigns after a white officer fatally shot 27—year—old rayshard brooks. the family's lawyer

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. i'm annita mcveigh. on today's programme, the world health organization says that up to 40% of coronavirus cases could come from people who have no symptoms. plus, we'll explore how artificial intelligence is helping in the fight against the virus. you can keep up to date with the latest information

about the pandemic on our website. first, there's growing evidence that a second wave of covid—i9 has hit iran, which was one of the earliest epicentres of the virus, but despite the increase in cases, there is no new lockdown in place yet for the 80 million people living there. some cities have already been announced as red zones for infection. bbc persia has this report. could this be iran's second wave of coronavirus? the country was opened up from lockdown just about a month ago. and this is how it looks like now in one city. buses are being used to transfer

covid—i9 patients to the capital of the province. it's one of at least nine provinces where infections are rising rapidly. according to iran's ministry of health, this province in the south—east is now a red zone. the hospitals are full. their staff are overwhelmed. last week, iran recorded the highest daily increase in the number of coronavirus cases since the first were reported four months ago. many local officials say this is a second wave of infections. but iran's president insists that the term ‘second wave‘ creates too much fear among people. there are no signs of social distancing here. shoppers and street vendors don't seem too worried. the authorities say this is the reason behind the recent spike, that people have ignored public health advice and travelled to other cities. translation: in last 24 hours, we learned that about 60—70% of the new patients in tehran hospitals have travelled to other cities recently. this has happened during eid al—fitr holidays, as we were expecting. as life begins to look relatively

normal in large parts of iran, most schools remain closed. but year 12 exams had to go ahead, which according to this student didn't feel safe. translation: they've taken our body temperature, but when we asked them about the results, we were told that the thermometer's broken. then they sent all the students to the exam zone. none of the desks were disinfected. when i wiped my desk with alcohol, the wipe went completely black. iran's official number of confirmed cases is around 176,000 cases, with over 8,000 deaths. but many, including the iranian parliament, believe the correct number of infections is 8—10 times more

and the deaths are at least twice as much. the president has warned that if people don't follow social distancing, the restrictions may be reimposed. but the economy, already badly hit by us sanctions and corruption, is on its knees. many say that iran can't afford another lockdown, even if the government wants to. the who has admitted there is a big unknown about how many coronavirus infections are caused by people who don't have symptoms of the disease. one of its scientists had suggested it was rare for the virus to be spread this way, but the organisation now says up to 40% of infections could come from people who have no sign of being ill, and that could make the virus harder to stop, as our science editor david shukman reports. this is a message from the government's chief medical officer about coronavirus.

if you or anyone in your house... for months, government advice has focused on symptoms, how you must isolate if you get them. you should all stay at home. but what about people who don't look as if they have the disease, but are still carrying the virus? like paramedic chelsie mason, who had a test for coronavirus and expected to be clear. i felt absolutely fine. came into work and had the test done, and then a couple of days later i got a call back saying it was positive, so really shocked because i had no symptoms whatsoever. so, how many cases are there without symptoms? a study at addenbrooke‘s hospital in cambridge found that 3% of the staff were positive, but didn't show it. in the us, at a care home in washington state, the numbers were higher. 56% of people with the virus had no indication of being ill. and on the diamond princess, a cruise ship offjapan, as many as 72% of positive cases

showed no symptoms at all. so, why does it matter if people have the infection, but don't have any symptoms? well, for two reasons. first, if someone becomes infected, it may take five days before they show any signs of illness, but for the 48 hours before their symptoms start, they could be passing the virus on. then there's the category of people who catch the virus and at no stage have any symptoms at all, maybe for ten days or more — no—one really knows. and scientists are desperate to find out how much they can spread the virus. one of the first things i thought about really was, "oh, my god, i've done two night shifts, i've come into contact with six or seven patients per night, i've been with my crewmate for 12 hours." as much as you minimise the risk, there is still that risk there, and with me being positive and not knowing about it, i could've passed it on. working out if that's going on now

is really difficult. the government's mainly testing people who may have symptoms. those who don't might slip through the net. so, scientists in norwich want to test the entire city, 100,000 people. they say it's the only way to discover who's spreading the virus. if you don't realise you're ill, as we come out of lockdown, and people are going to have more contacts than they did previously, the risk from those individuals is likely to increase. the upshot is that keeping a safe distance still matters, and where you can't, governments around the world are recommending face coverings in case you've got the virus and don't know it. david shukman, bbc news. almost 300,000 children in india could die due to severe malnutrition and lack of access to essential life—saving services over the next six months, according to a study

byjohns hopkins university. the rise in hunger has been made much worse by the coronavirus lockdown, with the country's daily wage earners suffering the most. millions have lost theirjobs and are struggling to feed theirfamilies. this report comes from delhi, where malnutrition levels in children were already some of the highest in the world. too much hunger, too little food. withjobs gone, it's a fight for survival. hunger was always an issue here, but this desperation is new. for these children just outside the capital, delhi, even one meal a day now feels like a triumph. shiva is just one—month—old. his parents rely on daily wages to buy food, and like millions

of others, they lost work after the government announced a lockdown in march. translation: we used to cook rice, rotis and vegetables before the lockdown. our children ate well. now they remain hungry because we have no money and no work. phoolmati's kids are too young to understand why this is happening. children under five are vulnerable to severe malnutrition. india is the worst in the world, with one in five children affected, and that might have become much worse. so, this is almost a perfect storm for malnutrition in this region, with a very vulnerable population, a decline in quality and quantity of diet, and without the access to the essential services that children need to prevent

and treat malnutrition. for children who were already malnourished, these months have been even harder. this two—year—old's mother says she has lost weight during the lockdown, and her condition could worsen as now they have very little government food support. for more than 45 years, the indian government has run a child development scheme to provide essential nutrients and vitamins to children under the age of six. during the lockdown, most of the more than 1 million centres shut down during lockdown. now, some of them are trying to home deliver a much smaller quantity of food supplements at a time when they're most critical for young child ren‘s development. now it's ordinary citizens who have stepped up. like neelesh singh, who has been distributing one hot meal a day to 500 children since

the past two months. but that's hardly enough. translation: i can provide one or two meals, but children need breakfast, lunch and dinner. they're not getting the nutrition they need. despite a surge in coronavirus cases, the lockdown is easing. the government has a huge dilemma — how to stop the deadly spread of the disease and protect the most vulnerable, particularly children, from hunger and even starvation. they haven't yet found all the answers. well, the united nations has estimated domestic abuse has increased by 20% globally during lockdown. some vital services have not been reaching people trapped with their abusers, but women all over the world have set up their own grassroots efforts to help vulnerable women in their own communities.

megha mohan has spoken with four women in four countries who set up projects to help their neighbours in need. alone and together, these women in the west bank are banging their pots and pans in protest against domestic violence. the un says cases of domestic abuse during the global pandemic have increased by 20%. so, now women all over the world have taken matters into their own hands to help other women in their neighbourhoods. during the west bank's eight—week lockdown, people stood on their balconies in the neighbourhood to let vulnerable women know that their homes were open to them. rabab, who's a woman's counsellor, has been using instagram and whatsapp to reach out to vulnerable women who may be trapped with their abusers.

more than 4,000 kilometres away in india, women have also set up a local phone line to take calls from isolated women.

the provinces that make up the area have some of the highest numbers of domestic violence in india. by taking dozens of calls a day, organising food deliveries, kavita can check in regularly with these women so they aren't trapped alone. it's impossible to socially distance in built—up poorer communities. brazil has one of the highest rates of domestic violence. government figures suggest that every two minutes,
