Bird flu may be ‘evolving under the radar’, scientists say
Bird flu could be “evolving under the radar” because of failures to monitor and control the spread of the virus, a leading pandemic scientist has warned.
Dr Thomas Peacock, a specialist in animal-to-human spread of viruses at The Pirbright Institute, said H5N1 could be transmitting undetected in the US because of “months of missing data” that leaves researchers, vets and authorities in the dark.
The strain is currently spreading between US dairy cows after crossing over from wild birds earlier in the year.
Four workers on cattle farms have also become infected and the Centers for Disease Control (CDC) recently reported the first human case with no known contact with animals.

Symptoms have been mild in all the people infected so far.
Dr Peacock said: “What keeps scientists up at night is the possibility of unseen chains of transmission silently spreading through farm worker barracks, swine barns, or developing countries, evolving under the radar because testing criteria are narrow, government authorities are feared, or resources are thin.”
In the US there is only mandatory reporting of the disease in poultry, not mammals. The Department of Agriculture only requires testing on lactating cattle before they are moved across state borders.
H5N1 has also spread in fur farms in Europe and globally in wild marine mammals.
Writing in the journal Nature, Dr Peacock and colleagues at The Pirbright Institute say the prospect of the highly pathogenic strain of bird flu becoming permanently established in Europe and the Americas is a “turning point”.

New control measures are needed, including vaccination, he said. Some vaccines for poultry already exist, but they don’t prevent infection.
And new mRNA jabs may be needed “at scale” if the virus starts spreading in humans.

“The severity of a future H5N1 pandemic remains unclear,” he said.
“Recent human infections with H5N1 (in the United States) have a substantially lower case fatality rate compared to prior H5N1 outbreak in Asia, where half of people with reported infections died.
“The lack of severity in US cases may be due to infection through the eye, rather than through viral pneumonia in the lung.”
The CDC said the current public health risk is low, but it is closely monitoring people exposed to infected animals.
Children are among the fatalities in a mass shooting at a child’s birthday party in California.
Police said four people had died and 10 were wounded in the incident in Stockton, about 60 miles east of San Francisco.
Officers were called on Saturday to a banquet hall just before 6pm local time (2am UK time) and district attorney Ron Freitas said children were among the dead.
He said the attacker was still at large.

“We can confirm at this time that approximately 14 individuals were struck by gunfire, and four victims have been confirmed deceased,” San Joaquin County Sheriff’s Office said on X.
The post said early indications suggest it could be a “targeted incident” but that information remains limited.
Police have so far not disclosed the attacker’s identity and the motive is unclear.
Stockton’s vice mayor Jason Lee confirmed on Facebook that the shooting on Lucile Avenue happened at a child’s birthday party.

Mayor Christina Fugazzi also said that “families should be together instead of at the hospital, standing next to their loved one, praying that they survive”.
California governor Gavin Newsom’s office added that he had been briefed on the “horrific shooting”.
Venezuela has accused Donald Trump of a “colonial threat” after he said the airspace “above and surrounding” the country should be considered closed “in its entirety”.
Mr Trump made the declaration amid growing tensions with President Maduro – and as the US continues attacking boats it claims are carrying drugs from Venezuela.
He wrote on Truth Social: “To all Airlines, Pilots, Drug Dealers, and Human Traffickers, please consider THE AIRSPACE ABOVE AND SURROUNDING VENEZUELA TO BE CLOSED IN ITS ENTIRETY.”

Venezuela’s foreign affairs office called it a “colonial threat” and “illegal, and unjustified aggression”.
It accused the president of threatening “the sovereignty of the national airspace… and the full sovereignty of the Venezuelan state”.
President Trump’s words were part of a “permanent policy of aggression against our country” that breached international law and the UN Charter, it added.
The Pentagon and the White House have so far not given any additional detail on the president’s statement.
Mr Trump’s post comes after the American aviation regulator last week warned of a “potentially hazardous situation” over Venezuela due to a “worsening security situation”.

The South American nation revoked operating rights for six major airlines that went on to suspend flights to the country.
Mr Trump warned a few days ago that land operations against suspected Venezuelan drug traffickers would begin “very soon”.
Such a move would be a major escalation in Operation Southern Spear – the US naval deployment in the Caribbean Sea and eastern Pacific that’s so far attacked at least 21 vessels.

Venezuela claims Trump creating ‘fables’ to justify ‘war’
The Pentagon has sought to justify the strikes by labelling the drug gangs as “foreign terrorist organisations” – putting them on par with the likes of al Qaeda.
It claims the boats targeted are carrying drugs bound for the US, although Sky’s chief correspondent says the final destination is likely to be Europe and West Africa.
President Maduro has denied Mr Trump’s claims he is involved in the drugs trade himself and said his counterpart wants to oust him so he can install a more sympathetic government.
Venezuelan officials have also claimed Mr Trump’s true motivation is access to the country’s plentiful oil reserves.
Mr Maduro is widely considered a dictator who’s cheated elections and has been president since 2013.
