Avian Influenza: Protecting Yourself from Bird Flu

This post offers an update on the bird flu outbreak in the United States. Bird flu, or avian influenza, primarily affects birds but can occasionally infect humans, especially through contact with sick birds. Recently, a severe H5N1 case resulted in one death in Louisiana. While human cases are rare, precautions include avoiding contact with wild birds and ensuring proper cooking of poultry products. Public health and agriculture agencies continue to monitor the situation.

Birds, just like people, can get the flu. Another name for bird flu is avian influenza. The viruses that cause bird flu normally only infect birds, including chickens, other poultry, and wild birds such as ducks. But sometimes the viruses can infect other animals and, in rare cases, people.

Bird flu is a subgroup of uncommon influenza A viruses that cause respiratory illness. These viruses are different from the influenza A viruses that cause seasonal flu.

People rarely get bird flu. When they do, it’s usually because they were in contact with infected birds or animals. Most bird flu infections in people have been caused by bird flu viruses called H5N1 and H7N9.

The H5N1 has been infecting birds and dairy cows in the United States for several months and has caused illness in several persons. Unfortunately, there has now been one confirmed death, as reported in this article by Greg LaRose.

Nation’s first ‘severe’ avian flu patient dies in Louisiana

The Louisiana patient who contracted what officials said was the nation’s first “severe” case of avian influenza has died, the state health department said Monday.The person who contracted the H5N1 strain of highly pathogenic bird flu in southwest Louisiana had been hospitalized since mid-December.

The patient was over age 65 and had an underlying medical condition, according to the Louisiana Department of Health. They contracted the virus from exposure to a combination of a non-commercial backyard flock and wild birds, officials have said.

State health workers have conducted an “extensive public health investigation” and identified no additional H5N1 cases nor evidence of person-to-person transmission, LDH said in a news release. The patient has been the only human case of H5N1 reported in Louisiana.

There have been 66 human cases of avian influenza confirmed in a total of 10 states, according to the U.S. Centers for Disease Control and Prevention. California has the most cases with 37, followed by Washington with 11 and Colorado with 10.

H5N1 infects birds and poultry. It can be passed on to humans who work in close contact with sick and dead birds. Human cases reported in other states have mostly been linked to dairy workers where the virus has been spread to cattle.

The virus can cause severe breathing problems and death in birds. Similar, severe flu-like symptoms can appear in humans, though the risk for public health is considered generally low.

More than 12,400 persons in the U.S. who believed they were exposed to avian influenza have been monitored, according to the Centers for Disease Control and Prevention. Of that number, 560 have been tested for H5NI, resulting in confirmation of the 63 cases.

State health officials say the best way for families to protect themselves from H5N1 is to avoid sources of exposure, such as direct contact with wild birds or other animals that might be infected.

Experts also advise against eating uncooked or undercooked food. Cooking poultry, eggs and other animal products to the proper temperature helps lower the risk from any possible contaminants.

For anyone who works on poultry or dairy farms, health officials suggest talking to a health care provider about getting a seasonal flu vaccination. It will not prevent infection with avian influenza viruses, but it can reduce the risk of coinfection with avian and flu viruses.

Sick birds or animals should be reported to the U.S. Department of Agriculture at 1-866-536-7593 or the Louisiana Department of Agriculture and Forestry Diagnostic Lab at 318-927-3441. (In other states contact your local agriculture or wildlife department for instructions.)

Persons who suspect they were exposed to sick or dead birds or other animals or work on a farm where avian influenza has been detected should watch for respiratory symptoms or conjunctivitis (pink eye).

If you develop such symptoms within 10 days after exposure to sick or dead animals, officials urge you to tell your health care provider you have been in contact with sick animals and are concerned about avian influenza. This information will help them give you appropriate advice on testing and treatment.

Anyone who suspects they are infected with avian flu should stay away from others while symptomatic.

H5 Bird Flu: Current Situation from the CDC

While the current public health risk is low, CDC is watching the situation carefully and working with states to monitor people with animal exposures. There is no known person-to-person spread.

CDC is using its flu surveillance systems to monitor for H5 bird flu activity in people. The surveillance systems show no indicators of unusual influenza activity in people, including avian influenza A(H5).

Bird Flu Testing in Dairy: USDA’s New Strategy to Prevent Infection

Birds, just like people, can get the flu. Another name for bird flu is avian influenza. The viruses that cause bird flu normally only infect birds, including chickens, other poultry, and wild birds such as ducks.

Bird flu can also infect many other animals, including dogs, cats, certain wild and zoo animals, and livestock such as cattle. Although this is rare, these animals can then spread the flu to people.

USDA launches national testing of milk from dairy farms to track bird flu outbreak

by Jennifer Shutt, Oklahoma Voice
December 9, 2024

WASHINGTON — The U.S. Department of Agriculture announced Friday it will require dairy farms to share samples of unpasteurized milk when requested, to gather more information about the spread of highly pathogenic avian influenza.

Public health officials have tracked the spread of bird flu or H5N1 in domestic poultry flocks for years before the virus began showing up in the country’s dairy herds this March, raising concerns.

While the risk to the general public remains low and there is no evidence to suggest bird flu can spread from person to person, nearly 60 people, mostly farmworkers, have contracted the virus this year.

The new milk testing requirements from USDA will apply nationally but will begin in California, Colorado, Michigan, Mississippi, Oregon, and Pennsylvania, the week of Dec. 16. 

“Among many outcomes, this will give farmers and farmworkers better confidence in the safety of their animals and ability to protect themselves, and it will put us on a path to quickly controlling and stopping the virus’ spread nationwide,”

Agriculture Secretary Tom Vilsack said in a written statement.

Unpasteurized milk

The U.S. Food and Drug Administration has repeatedly tested pasteurized milk on store shelves throughout the country to reaffirm it’s safe to drink. Other dairy products, like cheese and ice cream, have also been found safe.

But the FDA continues to urge people against consuming unpasteurized milk, since it doesn’t go through the heating process that kills off viruses and bacteria.

Health and Human Services Secretary Xavier Becerra said in a written statement the new milk “testing strategy is a critical part of our ongoing efforts to protect the health and safety of individuals and communities nationwide.”

“We continue to work closely with USDA and all stakeholders on continued testing for H5N1 in retail milk and dairy samples from across the country to ensure the safety of the commercial pasteurized milk supply,” Becerra said. “We will continue this work with USDA for as long and as far as necessary.”

“Our primary responsibility at HHS is to protect public health and the safety of the food supply,

The USDA began a voluntary bulk tank testing program for milk this summer in an attempt to make it easier for farmers to move their cattle across state lines without having to test each cow. The department also began a year-long study in August to test for bird flu in dairy cattle moved into meat production, seeking to confirm prior studies that found it safe to eat.

The bird flu outbreak has affected 720 dairy herds throughout 15 states so far this year, though California became the epicenter during the last month, according to data from the USDA.

The Golden State holds nearly all of the 273 herds diagnosed, with just four found in Utah during the last 30 days.

California also holds the bulk of bird flu infections in people, with 32 of the 58 diagnosed cases this year, according to information from the Centers for Disease Control and Prevention.

Colorado accounts for another 10 human cases and Washington state confirmed 11 people infected with H5N1. Michigan has had two cases this year, while Missouri, Oregon and Texas have each had one positive human case.

USDA order

The USDA federal order announced Friday will require anyone responsible for a dairy farm — such as a bulk milk transporter, bulk milk transfer station, or dairy processing facility — to share unpasteurized or raw milk samples when requested.

Any farm owners whose dairy herds test positive for H5N1 will be required to share epidemiological information that would allow public health officials to perform contact tracing and other types of disease surveillance. 

Additionally, private laboratories and state veterinarians must alert USDA to positive samples collected as part of this National Milk Testing Strategy.
