Birds across the United States can contract avian influenza, commonly known as bird flu or H5N1. But what does this mean for your family? Here’s what parents need to know about bird flu, how it spreads, and how to reduce exposure.
What Causes Bird Flu?
Bird flu is caused by avian influenza type A viruses, with the H5N1 strain currently circulating in the U.S. This virus primarily affects birds worldwide but has been detected in other animals and, in rare cases, humans.
Is Bird Flu Spreading in the U.S.?
Wild birds can carry and spread the virus, leading to outbreaks in poultry farms. In 2022, bird flu was found in wild birds in the U.S. for the first time since 2016, and multiple states have since reported cases in poultry and wild bird populations. These outbreaks have led to the loss of millions of chickens, impacting egg availability and prices.
Does Bird Flu Only Affect Birds?
While bird flu is most common in wild waterfowl such as ducks and geese, it can spread to other animals. The virus can be transmitted through an infected bird’s saliva, nasal discharge, and droppings. Families raising backyard poultry or keeping birds as pets should take precautions.
In 2024, bird flu was identified in dairy cattle for the first time, spreading concern beyond birds. Additionally, several cats in Texas died after drinking raw milk from infected cows, and some indoor cats became sick after consuming contaminated raw pet food. The virus has even been linked to the deaths of a flamingo and a seal at a Chicago zoo in early 2025.
Can Humans Get Bird Flu?
Though rare, bird flu can be transmitted to people. Since last year, more than 60 human cases have been reported in the U.S., including two children. In both cases, the children had mild symptoms and recovered after receiving antiviral treatment. However, a 13-year-old in Canada experienced severe illness, and in January 2025, an elderly person in Louisiana died after exposure to an infected backyard flock.
Most infections have occurred in individuals who work closely with poultry or dairy cattle, but a few cases had no clear source of exposure. While there have been no confirmed cases of human-to-human transmission, health officials continue to monitor the virus closely.
Symptoms of Bird Flu in People
Bird flu symptoms can vary from mild to severe and may include:
Fever
Cough and sore throat
Muscle aches
Shortness of breath and pneumonia
Nausea, vomiting, and diarrhea
Neurological issues such as confusion or seizures
Will the Flu Shot Protect Against Bird Flu?
The seasonal flu vaccine does not protect against bird flu. It is designed to prevent the most common strains of influenza circulating in humans. However, health officials strongly recommend the annual flu vaccine for everyone aged 6 months and older, as seasonal flu poses a greater risk.
Can Bird Flu Spread Through Meat or Dairy Products?
Eating properly cooked poultry, such as chicken, turkey, or duck, does not pose a risk of bird flu infection. Likewise, pasteurized dairy products are considered safe.
Is Raw Milk Safe?
Raw (unpasteurized) milk can carry harmful bacteria and viruses, including bird flu. Health officials advise against consuming raw milk due to the risk of exposure to dangerous pathogens like Salmonella, E. coli, and Listeria. Pasteurization effectively eliminates these threats by heating milk to a safe temperature.
Are Eggs Safe to Eat?
Yes, fully cooked eggs are safe to eat. However, raw eggs can carry bacteria such as Salmonella, which is why it’s best to avoid consuming raw or undercooked eggs, including in cookie dough or cake batter.
For those with backyard chickens, eggs should be cleaned properly with a dry cloth, brush, or fine sandpaper. Avoid washing warm eggs with cold water, as it can cause bacteria to enter through tiny pores in the shell.
Key Takeaways
Health officials continue to monitor bird flu outbreaks and their potential risks. To minimize exposure, families should:
Encourage frequent handwashing after handling birds or visiting areas with birds.
Supervise children around birds and discourage them from touching their face, eyes, or mouth.
Avoid handling sick or dead birds and report them to local authorities.
