WHO says vaccine-derived poliovirus detected in Papua New Guinea
May 20 (Reuters) - The World Health Organisation (WHO) said on Tuesday that circulating vaccine-derived poliovirus type 2 (cVDPV2) had been detected in stool specimens of two healthy children in Papua New Guinea on May 9.
The detection of wild poliovirus or vaccine-derived poliovirus, including from samples taken from healthy children, is considered a serious public health event, WHO said in a statement.
It added that the detection of circulating type 2 poliovirus was classified as a "polio outbreak".

Will norovirus surge early again this year? Here's what scientists say
Will the upcoming norovirus season be just as early and active as the past year? While the answer may be anyone's guess right now, federal health officials recently warned that the dominant strain of the contagious virus — the leading cause of vomiting, diarrhea, and foodborne illness in the U.S. — has changed between the 2022-2023 and 2024-2025 seasons. 'GII.17 has caused 75 percent of all norovirus outbreaks during the 2024–25 season so far, thereby replacing GII.4 as the predominant norovirus outbreak strain in the United States,' Centers for Disease Control researchers wrote in an article published this month by the agency's Emerging Infectious Diseases journal. This past season also started at the earlier date of October, as opposed to December. GII.17 also drove a record wave of outbreaks. But, what all of this might mean going forward needs further research. 'Additional sequence analysis of complete GII.17 genomes and identification of cross-protective neutralizing antibodies of GII.17 compared with GII.4 viruses could help clarify whether GII.17 viruses will persist. Continued surveillance is needed to determine if this genotype remains the dominant genotype, as well as whether the norovirus season continues to start earlier than previous years,' they wrote. A spokesperson for the agency told CBS News that there are 'currently insufficient historic data to predict whether norovirus GII.17 will remain the dominant genotype and lead to an earlier onset of the norovirus season later this year.' They pointed to a surge of GII.17 strains in Asia and Europe in 2014 that was followed by no reports of a change to seasonality, and noted that there has been no clear evidence to prove that GII.17's emergence was the cause of a change to the norovirus season last year. Still, this past season reached the worst levels in a decade. There were 91 suspected or confirmed outbreaks during the first week of December, which Yale Medicine said exceeded the number of outbreaks during the same week in any year since 2012. The majority were the GII.7 strain. In years when there is a new strain of the virus, there can be 50 percent more norovirus illness. Cases continued to tick up months into this year. By May 7, there were 2,571 outbreaks. During the same time last year, there were only 1,358. 'The total number of outbreaks reported during the 2024 to 2025 seasonal year is above the range reported during the same period during the 2012 to 2020 and 2021 to 2024 seasonal years,' the CDC said. But, cases in the previous season were lower than normal. Typically, there are about 2,500 reported norovirus outbreaks in the U.S. each year. Cases have fallen markedly since January, and are now at low levels. While the outbreaks occur throughout the year, they are the most common from November to April as people head indoors and it's easier to spread norovirus through infected particles. Anyone who consumes raw shellfish is also at risk of contracting it. Infection can be deadly largely among adults aged 65 and up, but anyone can get sick. Children younger than 5 years old and people with weakened immune systems are more likely to develop severe infections. There are 900 deaths on average each year and between 19 and 21 million illnesses. There's no specific treatment for norovirus, but most people recover with a period of up to three days. 'The norovirus can spread so quickly, but also, as we already talked about, norovirus can be very — it's usually very fast. So yeah, if people are taking care of themselves, we leave them alone,' explained Dr. Joanna Bisgrove, a family physician at Rush University Medical Center. 'But if it keeps going, we're like, maybe this isn't norovirus, and we need to do other things.'

Deadly flu variant wipes out 95% of animals at one of US's largest farms
A killer bird flu outbreak has hit multiple farms in Arizona - and the variant has wiped out millions of birds from one of the United States's largest egg producers. Chickens at Hickman Farms in Buckeye, Arizona began showing symptoms at the end of May. The initial loss was estimated at 1.1 million birds, but just two weeks after the flock got sick, 6 million have died. That accounted for about 95 percent of Hickman Farms' bird population. CEO Glenn Hickman held a press conference on May 30 to address the situation. To him, the loss was entirely preventable. 'If our pullets had been vaccinated when we started lobbying the federal government in January, our pullets would have been saved by now,' he said. Hickman and Hickman Family farms have been advocating for access to avian flu vaccines since January. According to the company's website, which addresses the situation, the U.S. government makes a vaccine, but only uses it as an export. 'European countries have now been vaccinating their flocks for a couple of years and are gaining the upper hand on controlling this disease. That vaccine is actually made here in the U.S., but we export to other countries while our flocks go unprotected.' The site encourages customers to contact their representatives in a continued push for access to vaccination. 'The quicker we can start vaccinating our nation's poultry flock, the quicker we can get back to normalized operations,' said Hickman. Hickman Farms is just the largest of several that have been affected in Arizona. On June 2, the Arizona Department of Agriculture confirmed that another farm in the Phoenix Metropolitan Area was placed under quarantine. The farm still remains unnamed, but per their press release, poultry began showing symptoms on May and tested positive on May 30. Hickman farms took similar measures to prevent spread, but now is focused on repopulating their farm. According to Hickman, the process of de-populating, cleaning and re-populating will take almost two years. They process will begin in just a few weeks. In the mean time, Hickman Farms has stopped operations. Hundreds of their 850 employees are out of the job - many of whom are contract workers and inmates. Fortunately, some employees will still be needed during the cleaning process. Customers of Hickman farms and other affected farms in Arizona do not need to be worried about contracting bird flu through consumption. The AZDA wrote in a press release on May 20 that eggs from chickens who tested positive have not entered food supply. 'There have been no signs of illness in humans,' they wrote. 'Consumers in Arizona and around the nation can remain confident in the safety and quality of eggs and egg products.' According to CDC numbers, only 70 human cases of bird flu have been reported in the past 14 months, including one death. The AZDA and the CDC said that humans at highest risk are those who have worked directly with affected poultry. Because of the outbreak, Arizona's Family reports that for the first time in 81 Hickman Farms will be unable to satisfy all of their customer demand. The company is looking for alternative ways to meet their needs. Not everyone is upset about the decline in operations. 12 News reports that nearby residents are happy to be rid of the stench that comes with operating a chicken farm. According to Fox 10, locals and environmental activists sued Hickman Farms in 2018 for polluting the area.

EXCLUSIVE I work as a rescue pilot in one of the world's most isolated jungles... I help those who have never accessed medical care and don't know what electricity is - people never believe what I've seen
Growing up, Mark Palm always knew he wanted to fly. It was in his blood. His grandfather was a World War II pilot, his uncles took to the skies, and his cousin served in the military as an aviator. But while most boys with an aviation pedigree dream of fast jets and high-flying careers, Mark's path took an unexpected turn - one that would lead him deep into the jungles of Papua New Guinea, where he would build a life-saving rescue service from scratch. Mark met villagers who had lost loved ones because they couldn't get to a hospital in time. Women died in childbirth. Children succumbed to snake bites. Malaria, tuberculosis, and infections ran rampant, but there was no way to get medical supplies to the remote settlements. 'We heard again and again about people dying just trying to reach help,' Mark told the MailOnline. 'Hospitals were two, three days away by canoe.' That's where his dream was born. His mission would see him ferrying desperate and sick villagers from their remote villages buried in the depths of the wilderness to the nearest hospital and cut the days-long trip down to one hour. Mark and his team at Samaritan Aviation have now delivered more than 100,000 pounds of medical supplied to over 20 aid stations and he has been the lead pilot on over 1,500 life-saving flights in the remote jungles of Papua New Guinea. It comes as The World Health Organisation recently declared a polio outbreak in Papua New Guinea and called for an 'immediate' vaccination campaign. When polio first returned to Papua New Guinea a few years ago, Samaritan Aviation partnered with the World Health Organisation to distribute vaccines to children living along the Sepik River. Without their planes, many of those children would have had no access to life-saving immunisations. Operating seven days a week, Mark and his team have transformed emergency healthcare in the region. 'We've been able to make that dream a reality,' he says. 'We've turned three-day journeys into one-hour flights. We've flown thousands of medevac missions - pregnant mothers in distress, snakebite victims, malaria patients, children injured in tribal fights. We've delivered medical supplies to remote villages. We've stopped disease outbreaks in their tracks.' But it all started when he was a teenager in California. His father, a minister, ran a homeless mission in Santa Cruz, and Mark would spend hours serving food to those in need. At 16, he crossed the border into Mexico on a mission trip, where he helped build homes for impoverished families. It was there, amid the dust and poverty, that Mark had an experience that changed his life forever. 'I just felt God speak to me,' the 50-year-old told MailOnline. 'It was like a conversation, as clear as we're talking right now. And He told me: "Mark, I want you to use your passion for people and aviation to share my love in a remote part of the world".' Mark had always planned on following in his grandfather's footsteps and joining the military. But after that moment, his vision shifted. Instead of war zones, he began thinking about isolated communities. Instead of combat missions, he imagined emergency rescues. A few years later, at a flight school in Florida, fate brought him together with a kindred spirit - a fellow aviation enthusiast who had been born in Papua New Guinea, the second largest island in the world. The two struck up a friendship, bonding over their love of flying, surfing, and adventure. Before long, they had a plan and spent a summer in Papua New Guinea, a country where more than 80 per cent of the population lives in remote villages with little or no access to healthcare, electricity, or running water. When Mark arrived in 1994, aged 19, he was stunned. 'It was like stepping into another world,' he says. 'People were living in bamboo huts with no electricity, no running water, no roads - just endless jungle and rivers.' But what struck him most were the tragic stories. The nearest hospitals were up to three days away, tribal fighting was an ongoing issue, people we rapidly giving up, and there was a scarcity of medical supplies. Mark and his friend started asking a simple question: What if we could turn a three-day journey into a one-hour flight? Back in the US, Mark threw himself into training. He studied aircraft mechanics, earned his pilot's license, and began forming a plan. He had discovered that Papua New Guinea had one major hospital serving a vast, roadless expanse along the Sepik River - a 700-mile stretch of water teeming with villages but utterly lacking in medical infrastructure. The solution seemed obvious - a seaplane. But there was just one problem, everyone told him it was impossible. 'There hadn't been a floatplane there in 40 years,' Mark says. 'People told us the river was too dangerous - crocodiles, flooding, unpredictable currents. They said we'd never survive, that we had to charge people for flights, that there was no way we could fund it.' But Mark refused to give up. He and his wife Kirsten launched Samaritan Aviation, a nonprofit dedicated to flying emergency medical missions - completely free of charge. In the early days, their fundraising efforts were discouraging. They sent out letters to 330 potential donors, expecting a wave of support. They received just $330 in return. Undeterred, they pressed on, telling their story to anyone who would listen. Over the years, they secured partnerships with the Papua New Guinea government and health officials. And finally, in 2010 - 10 years after first conceiving the idea - Mark, Kirsten, and their three young children boarded a plane to Papua New Guinea. Their seaplane followed in a shipping container. 'When we landed, we had nothing but a dream and a plane,' Mark says. 'We had to rebuild the aircraft from scratch, then fly it to our new base in Wewak.' Then, on Good Friday, 2010, he got the first emergency call. A woman had been in labor for three days and there was no way for her to reach the hospital. Mark loaded a stretcher into the plane and flew through rough weather, landing on the Sepik River in the rain. As he watched a group of villagers carry the woman toward the aircraft, he quickly realised how serious the situation was - she was completely unconscious. 'I wasn't a doctor. I was a pilot, a mechanic, a musician - I had no medical background,' Mark says. 'And now I was flying my first medevac, with a dying woman just a foot away from me.' The short flight felt like an eternity. Mark kept glancing at the woman whose head was laying just a foot away from him in the tiny aircraft - but all he could do was fly as fast as possible. When they landed, an ambulance rushed her into surgery. Mark went home, unsure if she had survived. The next day, he returned to the hospital with his wife and kids to find her sitting up in bed, holding a healthy baby boy. 'It's a long story, but they ended up giving him my name and so the first patient we ever flew in was Antonio - the mum who survived, and then the baby was baby Mark which is such an honour'. Fifteen years later, that baby, Baby Mark, is almost 15 years old. His mother, Antonia, recently became a grandmother. 'That's an entire generation we've impacted,' Mark says. 'And that's just one of the thousands of lives we've touched.' Fifteen years later, Samaritan Aviation has become a lifeline for thousands of people. The team has also expanded. Mark and Kirsten spent a decade in Papua New Guinea, but today, Samaritan Aviation has three seaplanes and a full-time staff of pilots, mechanics, and medical personnel who live there, raising their own financial support from friends and churches. 'They move over for two years at a time, bringing their families with them,' Mark explains. Right now, Samaritan Aviation is building eight houses and a training center to accommodate their growing team. But their work isn't just about flying patients from point A to point B. 'A lot of the people we pick up have never left their villages,' Mark says. 'They've never seen the ocean, electricity, cars, running water. And now, in the middle of a medical crisis, we're taking them away from everything they know'. That's why Samaritan Aviation doesn't just drop patients at the hospital and leave. 'We have a team of Papua New Guineans who come in every day. They feed the patients we bring in, they clothe them if they need clothes, they pray with them, they love on them.' For Mark, this is what it's all about. 'It's more than just rescue flights,' he says. 'It's about being part of their lives when they're at their lowest, showing them love, giving them hope.' Samaritan Aviation now serves 120 villages - over 500,000 people - on the Sepik River. And they're not stopping there. 'We're expanding to the other side of the island,' Mark says. 'In the Gulf Province, there are hundreds of thousands of people with no roads, no medical access. Their hospitals are two, three days away. They've been forgotten.' After years of groundwork, Samaritan Aviation has secured partnerships with the Gulf government and Gulf Christian Services, which runs hospitals in remote villages. They've just built a floating dock in one of the region's most isolated areas, where water levels rise and fall by nine feet a day. 'We had a team out there for a month in January, dredging a landing area in the swamp,' Mark says. 'And I'm going back in May to bring a plane over and start medical flights.' It's a major milestone. 'For me, it's incredible to see how this has grown,' he says. 'We're celebrating 25 years as an organisation this year. 15 years in Papua New Guinea. And now, we get to take everything we've learned and offer that same hope to even more people.' When Mark first dreamed of flying, he imagined adventure, excitement, maybe even military glory. Instead, he found a calling - one that has saved lives, transformed communities, and proven that one plane, one vision, and one unshakable belief can change the world.
