Next pandemic likely to be caused by flu virus, scientists warn

Sat 20 Apr 2024 09.52 BST

Influenza is the pathogen most likely to trigger a new pandemic in the near future, according to leading scientists.

[...]

The belief that influenza is the world’s greatest pandemic threat is based on long-term research showing it is constantly evolving and mutating, said Cologne University’s Jon Salmanton-García, who carried out the study.

Last week, the World Health Organization raised fears about the alarming spread of the H5N1 strain of influenza that is causing millions of cases of avian flu across the globe. This outbreak began in 2020 and has led to the deaths or killing of tens of millions of poultry and has also wiped out millions of wild birds.

Most recently, the virus has spread to mammal species, including domestic cattle which are now infected in 12 states in the US, further increasing fears about the risks to humans. The more mammalian species the virus infects, the more opportunities it has to evolve into a strain that is dangerous to humans, Daniel Goldhill, of the Royal Veterinary College in Hatfield, told the journal Nature last week.

The appearance of the H5N1 virus in cattle was a surprise, added virologist Ed Hutchinson, of Glasgow University. "Pigs can get avian flu but until recently cattle did not. They were infected with their own strains of the disease. So the appearance of H5N1 in cows was a shock."

First case of walrus dying from bird flu recorded in Arctic

Virus has already killed other mammals including sea lions and seals, while also taking toll on farm animals

Tue 30 Apr 2024 06.01 BST

The first case of a walrus dying from bird flu has been detected on one of Norway’s Arctic islands, a researcher has said.

The walrus was found last year on Hopen island in the Svalbard archipelago, Christian Lydersen, of the Norwegian Polar Institute, told AFP.

Tests carried out by a German laboratory revealed the presence of bird flu, Lydersen said. The sample was too small to determine whether it was the H5N1 or the H5N8 strain.

“It is the first time that bird flu has been recorded in a walrus,” Lydersen said.

About six dead walrus were found last year in the Svalbard islands, about 1,000km (620 miles) from the north pole and halfway between mainland Norway and the north pole.
