A major U.S. farmworker union is warning that the number of people infected with H5N1 avian influenza may be substantially higher than official figures indicate, raising concerns about gaps in disease surveillance as the virus continues spreading through dairy cattle herds.^[1]

Key Facts

Disease: H5N1 Bird Flu
Where: Location not yet reported
Status: Reported by State of Delaware News (.gov)^[2]
Outlets reporting: 10
Official source: State of Delaware News (.gov)

The Threat

The United Farm Workers (UFW) union says it has received reports from dairy employees in Washington State’s Yakima Valley who are experiencing symptoms consistent with avian influenza but have not undergone testing.^[1]

The allegations follow the death of a dairy worker infected with H5N1 and the confirmation of two additional human cases associated with infected cattle in the region.^[1]

According to the Yakima Health District, three human infections have been confirmed in the county, including one fatal case reported on November 1. However, union representatives believe additional illnesses may be going undetected because some agricultural workers are reluctant to seek testing or miss work.^[1]

State of Delaware News (.gov) says: Earlier this week, a case of highly pathogenic H5N1 avian influenza (HPAI) was confirmed at a commercial broiler farm in Worcester County, Maryland. If you see a sick or dead wild bird on public or private property, report sightings through the Delaware Department of Natural Resources and Environmental Control’s Division of Fish and Wildlife’s sick and injured wildlife reporting form.^[2]

Transmission Method

What the reports say about exposure and spread: Nevertheless, the reports raise questions about whether current surveillance is capturing the full extent of occupational exposure among people working directly with infected dairy cattle. However, inadequate testing can make it more difficult for public health authorities to identify infected individuals, evaluate transmission patterns, and determine whether additional protective measures are necessary.^[1]

How H5N1 bird flu spreads, according to the World Health Organization: People catch bird flu through direct or indirect contact with infected animals: handling, slaughtering or preparing infected poultry, live bird markets, and contaminated surroundings. In 2024 H5N1 reached dairy cattle in the United States and infected some farm workers. The bird flu viruses circulating now have not shown sustained spread from person to person.^[3]

Affected Regions

Places named in the reports: Washington, Oregon, Indiana, United States, Maryland, Delaware.

Federal influenza surveillance data reviewed in a November 9 risk assessment identified 75 confirmed human cases nationally during the current outbreak period, including the Washington infections.^[1]
Delaware backyard flock owners who notice dead birds or any unusual signs in their flock should email poultry.health@delaware.gov or call the Delaware Poultry Health Hotline at 302-698-4507 and provide your contact information, size of flock, location, and concerns.^[2]

What Is Not Confirmed

Although some employees reportedly received protective supplies, the organization questioned whether workers were receiving sufficient training to use that equipment effectively.^[1]
Such a development could substantially alter the virus’s public health implications, although there is currently no evidence that the virus has acquired the ability to sustain human-to-human transmission.^[1]

Holistic & Immune Defense Outlook

There is no herb, supplement or diet that has been shown to prevent or cure H5N1 bird flu. Health authorities should be told about anyone suspected of having bird flu. Patients are tested, isolated and treated, for example with antivirals and supportive care. If you have symptoms after a possible exposure, the most important step is to see a clinician quickly and tell them where you have been.

The World Health Organization’s protective steps for this disease:

Avoid contact with sick or dead animals, including wild birds, and report them to local wildlife or veterinary authorities.
Wash your hands with soap and running water before and after contact with animals.
Handle, store and cook eggs, meat and other animal products properly.

What a whole-body approach can do is keep your baseline strong, so your body is better able to respond when it meets any infection. The basics have the best evidence behind them: steady sleep, a diet rich in vegetables, fruit, beans and whole grains, enough water, regular movement, and keeping routine vaccinations current.

What CBC Reports

Avian flu has been detected in three flocks, including in Manitoba and Alberta, following an outbreak at a national poultry show in Saskatchewan earlier this month, the Canadian Food Inspection Agency has told CBC News. Three cases of highly pathogenic avian influenza (HPAI) have been detected in the Prairie provinces and “additional cases may be confirmed as the disease investigation proceeds,” the CFIA statement says.^[4]
