WASHINGTON: A person in the state of Missouri has become the first in the United States to test positive for bird flu without a known exposure to infected animals, authorities said on Friday.
The adult patient, who has underlying conditions, was admitted to hospital on August 22, received antiviral medications against influenza, then recovered and was discharged, according to statements from the Centers for Control and Disease Prevention (CDC) and the Missouri Department of Health and Senior Services.
As the patient’s flu type appeared suspicious on an initial test, it was sent for additional testing in state and federal laboratories, which revealed it was H5, also known as avian flu or bird flu.
The CDC said it had not identified any transmission to the patient’s close contacts or any other person.
Scientists have voiced concern about the growing number of mammals becoming infected by bird flu, even if cases in humans remain rare.
They fear a high rate of transmission could facilitate a mutation of the virus, which could enable it to be passed from one human to another.
Contacted by AFP, the World Health Organization said on Saturday it was “encouraging that the national disease surveillance system has identified this case, that the patient received antiviral treatment, and that no further cases have been detected among close contacts.”
“It is critical that investigations into the patient’s exposure are continued, as indicated by national and state authorities, to inform further prevention and response activities,” said Dr. Maria Van Kerkhove, the WHO’s director of epidemic and pandemic preparedness and prevention.
“WHO strongly supports US efforts for surveillance of zoonotic influenza across human, environmental and animal sectors,” Van Kerkhove continued.
“It is important to understand the circulation of avian influenza in poultry, wild birds and other animals in the state,” she said of Missouri.
“Stronger disease surveillance in animals is essential to protect animal and human health.”
The person who tested positive for bird flu was the 14th to do so in the US this year, and the first without known contact with animals.
Indeed, “no H5 infection in dairy cattle has been reported in Missouri,” said the Missouri health department, though “some H5 cases in commercial or backyard flocks and wild birds have been reported.”
All previous bird flu cases in the United States have been among farmworkers, including the very first, in 2022.
Bird flu is most commonly found in wild birds and poultry, but has more recently been detected in mammals, with an outbreak in cattle seen across the country this year.
It can occasionally infect humans through close contact or contaminated environments.
While the CDC continues to assess the risk to the public as low, “circumstances may change quickly as more information is learned,” it said.
In the decades since H5 has been found in humans, there have been rare cases where an animal source cannot be identified.
But there has so far not been evidence of sustained human-to-human transmission, which would significantly increase the threat level.

Afghan mothers seek hospital help for malnourished children
HERAT: Najiba, 24, keeps a constant watch over her baby, Artiya, one of around four million children at risk of dying from malnutrition this year in Afghanistan.
After suffering a bout of pneumonia at three months old, Artiya’s condition deteriorated and his parents went from hospital to hospital trying to find help.
“I did not get proper rest or good food,” affecting her ability to produce breast milk, Najiba said at Herat Regional Hospital in western Afghanistan.
“These days, I do not have enough milk for my baby.”
The distressed mother, who chose not to give her surname for privacy reasons, said the family earns a living from an electric supplies store run by her husband.
Najiba and her husband spent their meagre savings trying to get care for Artiya, before learning that he has a congenital heart defect.
To her, “no one can understand what I’m going through. No one knows how I feel every day, here with my child in this condition.”
“The only thing I have left is to pray that my child gets better,” she said.
John Aylieff, Afghanistan director at the World Food Programme (WFP), said women are “sacrificing their own health and their own nutrition to feed their children.”
Artiya has gained weight after several weeks at the therapeutic nutrition center in the Herat hospital, where colorful drawings of balloons and flowers adorn the walls.
Mothers such as Najiba, who are grappling with the reality of not being able to feed their children, receive psychological support.
Meanwhile, Artiya’s father is “knocking on every door just to borrow money” which could fund an expensive heart operation on another ward, Najiba said.
- ‘Staggering’ scale -
On average, 315 to 320 malnourished children are admitted each month to the center, which is supported by medical charity Doctors Without Borders (MSF).
The number of cases has steadily increased over the past five years, according to Hamayoun Hemat, MSF’s deputy coordinator in Herat.
Since the Taliban regained power in 2021, low-income families have been hit hard by cuts to international aid, as well as drought and the economic fallout of five million Afghans forced across the border from Iran and Pakistan.
“In 2025, we’d already seen the highest surge in child malnutrition recorded in Afghanistan since the beginning of the 21st century,” Aylieff said in Kabul.
The crisis is only set to worsen this year, he told AFP: “A staggering four million children in this country will be malnourished and will require treatment.”
“These children will die if they’re not treated.”
WFP is seeking $390 million to feed six million Afghans over the next six months, but Aylieff said the chance of getting such funds is “so bleak.”
Pledges of solidarity from around the globe, made after the Taliban government imposed its strict interpretation of Islamic law, have done little to help Afghan women, the WFP director said.
They are now “watching their children succumb to hunger in their arms,” he said.
- ‘No hope’ -
In the country of more than 40 million people, there are relatively few medical centers that can help treat malnutrition.
Some families travel hundreds of kilometers (miles) to reach Herat hospital as they lack health care facilities in their home provinces.
Wranga Niamaty, a nurse team supervisor, said they often receive patients in the “last stage” where there is “no hope” for their survival.
Still, she feels “proud” for those she can rescue from starvation.
In addition to treating the children, the nursing team advises women on breastfeeding, which is a key factor in combating malnutrition.
Single mothers who have to work as cleaners or in agriculture are sometimes unable to produce enough milk, often due to dehydration, nurse Fawzia Azizi said.
The clinic has been a lifesaver for Jamila, a 25-year-old mother who requested her surname not be used out of privacy concerns.
Jamila’s eight-month-old daughter has Down’s syndrome and is also suffering from malnutrition, despite her husband sending money back from Iran where he works.
Wrapped in a floral veil, Jamila said she fears for the future: “If my husband is expelled from Iran, we will die of hunger.”
