WHO concerned about bird flu after girl’s father tests positive

PARIS, Feb 25, (AFP) - The World Health Organization expressed concern about bird flu on Friday after the father of a 11-year-old Cambodian girl who died from the disease also tested positive, raising fears of human-to-human transmission.

Since late 2021, one of the worst global avian influenza outbreaks on record has seen tens of millions of poultry culled, mass wild bird die-offs and a rising number of infections among mammals.

In Cambodia, the girl fell ill on February 16 with a fever, cough and sore throat, and died on Wednesday from the H5N1 bird flu virus, according to the health ministry.

Authorities then collected samples from 12 people who had been in contact with her.

On Friday, the authorities said the girl's 49-year-old father had tested positive, adding that he was asymptomatic.

The WHO said it was in close contact with the Cambodian authorities about the situation, including regarding the test results of the girl's other contacts.

Humans rarely get bird flu, but when they do it is usually from coming in direct contact with infected birds.

Investigators in Cambodia are working to establish whether the girl and father were exposed to infected birds.

Officials are also waiting for test results from several dead wild birds found near the girl's remote village in the eastern Prey Veng province.

“So far, it is too early to know if it's human-to-human transmission or exposure to the same environmental conditions,” Sylvie Briand, WHO epidemic and pandemic preparedness and prevention director, told a virtual press conference.

Earlier this month, WHO chief Tedros Adhanom

Ghebreyesus said the risk of bird flu to humans was low, and Briand emphasised that this assessment had not changed.

But she added that the UN agency was reviewing the available information to see if this risk assessment needs to be updated.

“The global H5N1 situation is worrying given the wide spread of the virus in birds around the world, and the increasing reports of cases in mammals including humans,” Briand said.

“WHO takes the risk from this virus seriously and urges heightened vigilance from all countries,” she added.

So far, cases of bird flu in humans had been “sporadic”, Briand said.

Humans rarely get bird flu, but when they do it is usually from coming in direct contact with infected birds.
