Yes, Bird Flu Is Still Around in 2024

Yes, bird flu is still around in 2024, with ongoing outbreaks affecting both wild and domestic bird populations across multiple continents. The highly pathogenic avian influenza (HPAI) H5N1 strain remains particularly active, contributing to what experts describe as the most widespread and persistent bird flu epidemic in recorded history. Monitoring efforts by global health organizations such as the World Organisation for Animal Health (WOAH) and the U.S. Centers for Disease Control and Prevention (CDC) confirm continuous transmission among migratory birds, backyard flocks, and commercial poultry operations. This sustained presence means that bird flu continues to pose risks to animal health, agricultural economies, and—though less commonly—human populations.

Understanding Bird Flu: A Biological Overview

Bird flu, or avian influenza, refers to a group of influenza viruses that primarily infect birds. These viruses belong to the Orthomyxoviridae family and are classified based on two surface proteins: hemagglutinin (H) and neuraminidase (N). There are 18 known H subtypes and 11 N subtypes, but the H5 and H7 strains are of greatest concern due to their potential to mutate into highly pathogenic forms.

The current global situation is dominated by the H5N1 subtype, which has evolved into multiple genetic clades over the past two decades. Since its emergence in Asia in the late 1990s, H5N1 has undergone significant changes, enabling it to spread more efficiently among wild birds and survive longer in the environment. Unlike earlier strains that caused isolated outbreaks, today’s H5N1 circulates continuously in bird populations, especially among waterfowl such as ducks, geese, and swans, which serve as natural reservoirs.

Transmission occurs through direct contact with infected birds, contaminated feces, saliva, or respiratory secretions. The virus can also persist on surfaces, equipment, and clothing, making biosecurity critical for farms and backyard poultry owners. While most cases occur in birds, spillover infections have been documented in mammals—including foxes, seals, minks, and even domestic cats—raising concerns about adaptive mutations that could increase zoonotic risk.

Global Spread and Geographic Hotspots in 2024

Bird flu activity in 2024 remains elevated across North America, Europe, Africa, and parts of Asia. In the United States, the U.S. Department of Agriculture (USDA) reports recurring detections in commercial poultry flocks and wild birds in over 40 states. Major outbreaks have affected turkey and egg-laying chicken farms, leading to the depopulation of millions of birds to prevent further spread.

In Europe, countries including France, Germany, Poland, and the United Kingdom continue to report seasonal surges linked to migratory bird pathways. The spring and fall migration periods typically see increased viral detection, as infected birds travel along flyways and introduce the virus to new regions. Similarly, in Africa, Egypt and Nigeria have experienced repeated outbreaks in backyard poultry, where limited veterinary infrastructure complicates control efforts.

Asia, where avian influenza originated, still sees endemic circulation in certain areas, particularly in live bird markets and smallholder farms. China, India, and Indonesia maintain surveillance programs, though underreporting remains a challenge in some rural zones. Meanwhile, South America has reported sporadic cases, indicating possible introduction via migratory species crossing from North America.

Region	Current Status (2024)	Key Affected Species	Human Cases Reported?
North America	Widespread in wild and domestic birds	Ducks, geese, turkeys, chickens	Rare; limited human exposure
Europe	Seasonal peaks during migration	Swans, gulls, poultry	Isolated cases in close contacts
Asia	Endemic in several countries	Chickens, ducks, migratory waterfowl	Occasional spillover
Africa	Recurrent outbreaks	Backyard poultry, wild birds	Low incidence
South America	Sporadic introductions	Wild birds, some poultry	No confirmed cases

Impact on Poultry Industry and Food Supply

The persistence of bird flu has had profound economic consequences. In the U.S., major outbreaks have led to spikes in egg prices due to the culling of layer hens. Between 2022 and 2024, over 60 million poultry birds were affected, disrupting supply chains and increasing production costs. Export restrictions imposed by trading partners further compound financial losses for farmers.

To mitigate these impacts, many commercial farms have enhanced biosecurity measures, including restricted access zones, mandatory disinfection protocols, and surveillance testing. Backyard flock owners are encouraged to keep birds indoors during high-risk seasons and avoid visiting other poultry sites. Despite these efforts, complete eradication remains unlikely due to the role of asymptomatic wild carriers.

Human Health Risks and Public Awareness

While bird flu does not easily transmit from birds to humans, rare cases have occurred—typically among individuals with prolonged, unprotected exposure to infected birds. Symptoms in humans range from mild respiratory illness to severe pneumonia and multi-organ failure. As of mid-2024, fewer than 900 human cases of H5N1 have been reported globally since 2003, with a mortality rate exceeding 50%.

Public health agencies emphasize that the risk to the general population remains low. However, the CDC and WHO closely monitor any signs of sustained human-to-human transmission, which could signal the emergence of a pandemic strain. Current antiviral medications like oseltamivir (Tamiflu) are effective if administered early, and vaccine candidates are being developed for potential use in at-risk groups.

Implications for Birdwatchers and Outdoor Enthusiasts

For birdwatchers, the continued presence of bird flu necessitates cautious observation practices. While enjoying nature is safe, direct contact with sick or dead birds should be avoided. Observers are advised to:

• Maintain distance from wildlife, especially waterfowl and shorebirds.
• Avoid touching dead birds; instead, report them to local wildlife authorities.
• Clean binoculars, cameras, and footwear after visits to wetlands or lakes.
• Do not feed wild birds in areas with known outbreaks.

National parks and wildlife refuges may temporarily close certain trails or viewing areas during active outbreaks. Checking official websites before visiting helps ensure compliance with safety guidelines and supports conservation efforts.

Myths and Misconceptions About Bird Flu

Several misconceptions persist about avian influenza. One common myth is that eating properly cooked poultry or eggs can transmit the virus. Scientific evidence confirms that standard cooking temperatures (above 165°F or 74°C) destroy the virus, making food safe when handled hygienically.

Another misconception is that bird flu is no longer a threat because it has been around for years. In reality, the virus continues to evolve, and its geographic reach and host range have expanded significantly. Some believe that only domestic birds are at risk, but wild populations—including endangered species—are increasingly affected.

How to Stay Informed and Take Preventive Measures

Staying updated on bird flu activity is essential for farmers, pet bird owners, and outdoor recreationists. Reliable sources include:

• CDC Avian Influenza Page: Provides updates on human cases and prevention strategies.
• USDA Animal and Plant Health Inspection Service (APHIS): Publishes real-time data on poultry outbreaks and control actions.
• WOAH (World Organisation for Animal Health): Offers global situation reports and international trade implications.
• Local Extension Offices: Deliver region-specific guidance for backyard flock management.

Preventive steps include vaccinating poultry where approved, isolating new or sick birds, and practicing strict hygiene when handling animals. Hunters should wear gloves when processing game birds and avoid harvesting visibly ill animals.
