Deadly Bird Flu Jumps to U.S. Pigs: A Looming Threat to Human Health
Avian Flu Outbreak in Oregon Pigs Raises Concerns for Human Health
A recent outbreak of avian flu in pigs on an Oregon farm has raised concerns about the potential threat to human health. The U.S. Department of Agriculture announced the discovery of the virus in pigs on a backyard farm in Crook County, marking the first time the virus has been found in U.S. pigs.
The outbreak occurred on a farm where a variety of animals share water and are housed together. After the virus was discovered in the farm’s poultry, one in five pigs on the farm were found to be infected. The farm was quarantined, and all five pigs were euthanized to prevent the spread of the virus.
According to Jennifer Nuzzo, an infectious disease researcher at Brown University, the discovery of avian flu in pigs raises concerns that the virus may be a stepping stone to a greater threat to people. Pigs can be infected with different types of flu, and animals may play a role in making avian viruses more adaptable to humans.
Nuzzo noted that the 2009 H1N1 flu pandemic originated in pigs, highlighting the potential for avian flu to spread to humans. However, the USDA conducted genetic testing on the farm’s poultry and found no mutations that suggested an increased ability of the virus to spread to people.
Troy Sutton, a Penn State researcher who studies flu viruses in animals, emphasized that the risk to the public remains low at this time. “It’s not a one-to-one relationship where pigs get infected with the virus and cause an epidemic,” he said.
The Oregon swine outbreak is “noteworthy, but does it change the threat level calculation? No, it’s not,” Sutton said. If the virus begins to spread more widely among pigs and subsequently leads to human infections, “then we will be more worried.”
So far this year, about 40 human cases of avian flu have been reported in the United States, with mostly mild symptoms including red eyes. All but one of the people had had contact with an infected animal.
