Bird flu outbreaks in mammals double, raising human risk: Report

Al Arabiya23-05-2025

Outbreaks of bird flu in mammals more than doubled across the world last year, raising the risk that the virus could potentially spread between humans, an international agency warned on Friday.
Avian influenza has spread across the world like never before in the last few years, leading to the mass culling of poultry, sending egg prices soaring and causing the deaths of several people in contact with infected animals.
While the overall risk of human infection remains low, bird flu outbreaks among mammals such as cattle, dogs and cats increase the possibility that the virus could eventually adapt to transmit between humans, the World Organization for Animal Health (WOAH) said in a new report.
The number of mammal outbreaks soared to 1,022 across 55 countries last year, compared to 459 in 2023, according to the Paris-based agency, which monitors animal diseases worldwide.
'It is concerning because it is a change in the pattern of the epidemiology of the virus,' WOAH's director general Emmanuelle Soubeyran told AFP.
Health experts have been sounding the alarm about the potential pandemic threat posed by bird flu, which has shown signs of mutating as it spreads in particular among dairy cows in the United States.
The new report comes as the budgets of US health and science agencies have been slashed by the Trump administration.
This included the sacking earlier this year of the staff of an epidemiology program known as the 'disease detectives.'

French Scientists Find New Blood Type in Guadeloupe Woman

A French woman from the Caribbean island of Guadeloupe has been identified as the only known carrier of a new blood type, dubbed "Gwada negative," France's blood supply agency has announced. The announcement was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of surgery, the French Blood Establishment (EFS) said on Friday. "The EFS has just discovered the 48th blood group system in the world!" the agency said in a statement on social network LinkedIn. "This discovery was officially recognized in early June in Milan by the International Society of Blood Transfusion (ISBT)." The scientific association had until now recognized 47 blood group systems. Thierry Peyrard, a medical biologist at the EFS involved in the discovery, told AFP that a "very unusual" antibody was first found in the patient in 2011. However, resources at the time did not allow for further research, he added. Scientists were finally able to unravel the mystery in 2019 thanks to "high-throughput DNA sequencing", which highlighted a genetic mutation, Peyrard said. The patient, who was 54 at the time and lived in Paris, was undergoing routine tests before surgery when the unknown antibody was detected, Peyrard said. This woman "is undoubtedly the only known case in the world," said the expert. "She is the only person in the world who is compatible with herself," he said. Peyrard said the woman inherited the blood type from her father and mother, who each had the mutated gene. The name "Gwada negative", which refers to the patient's origins and "sounds good in all languages", has been popular with the experts, said Peyrard. The ABO blood group system was first discovered in the early 1900s. Thanks to DNA sequencing, the discovery of new blood groups has accelerated in recent years. Peyrard and colleagues are now hoping to find other people with the same blood group. "Discovering new blood groups means offering patients with rare blood types a better level of care," the EFS said.

Early humans survived in a range of extreme environments before global migration, study says

WASHINGTON: Humans are the only animal that lives in virtually every possible environment, from rainforests to deserts to tundra. This adaptability is a skill that long predates the modern age. According to a new study published Wednesday in Nature, ancient Homo sapiens developed the flexibility to survive by finding food and other resources in a wide variety of difficult habitats before they dispersed from Africa about 50,000 years ago. 'Our superpower is that we are ecosystem generalists,' said Eleanor Scerri, an evolutionary archaeologist at the Max Planck Institute of Geoanthropology in Jena, Germany. Our species first evolved in Africa around 300,000 years ago. While prior fossil finds show some groups made early forays outside the continent, lasting human settlements in other parts of the world didn't happen until a series of migrations around 50,000 years ago. 'What was different about the circumstance of the migrations that succeeded — why were humans ready this time?' said study co-author Emily Hallett, an archaeologist at Loyola University Chicago. Earlier theories held that Stone Age humans might have made a single important technological advance or developed a new way of sharing information, but researchers haven't found evidence to back that up. This study took a different approach by looking at the trait of flexibility itself. The scientists assembled a database of archaeological sites showing human presence across Africa from 120,000 to 14,000 years ago. For each site, researchers modeled what the local climate would have been like during the time periods that ancient humans lived there. 'There was a really sharp change in the range of habitats that humans were using starting around 70,000 years ago,' Hallett said. 'We saw a really clear signal that humans were living in more challenging and more extreme environments.' While humans had long survived in savanna and forests, they shifted into everything from from dense rainforests to arid deserts in the period leading up to 50,000 years ago, developing what Hallett called an 'ecological flexibility that let them succeed.' While this leap in abilities is impressive, it's important not to assume that only Homo sapiens did it, said University of Bordeaux archaeologist William Banks, who was not involved in the research. Other groups of early human ancestors also left Africa and established long-term settlements elsewhere, including those that evolved into Europe's Neanderthals, he said. The new research helps explain why humans were ready to expand across the world way back when, he said, but it doesn't answer the lasting question of why only our species remains today.
