Yes, Bird Flu Is Going Around in 2024

Yes, bird flu is going around in various regions across the globe in 2024, with ongoing outbreaks affecting both wild birds and commercial poultry flocks. The current strain circulating widely is H5N1, a highly pathogenic avian influenza (HPAI) virus that has led to one of the most extensive epizootics in recorded history. Known as avian influenza or simply bird flu, this viral disease primarily affects birds but has shown increased spillover potential into mammals—and occasionally humans—raising public health concerns. As of mid-2024, cases have been confirmed in over 80 countries, including widespread detection in North America, Europe, and parts of Asia, making it critical for birdwatchers, farmers, and public health officials to stay informed about transmission patterns, symptoms, and safety measures related to bird flu activity.

Understanding Avian Influenza: What Is Bird Flu?

Bird flu, or avian influenza, refers to a group of influenza A viruses that naturally occur in wild aquatic birds such as ducks, geese, swans, and shorebirds. These species often carry the virus without showing signs of illness, acting as reservoirs for transmission. However, when the virus spreads to domestic poultry—including chickens, turkeys, and farmed game birds—it can cause severe disease and high mortality rates, especially with highly pathogenic strains like H5N1.

The virus belongs to the Orthomyxoviridae family and is classified based on two surface proteins: hemagglutinin (H) and neuraminidase (N). There are 18 known H subtypes and 11 N subtypes, leading to numerous combinations. While many are low-pathogenic and cause mild respiratory issues, certain variants—particularly H5 and H7 subtypes—can mutate into highly pathogenic forms under specific conditions.

Current Status of Bird Flu Outbreaks in 2024

In 2024, bird flu remains actively present in multiple continents. According to data from the World Organisation for Animal Health (WOAH) and national surveillance programs, there have been thousands of reported outbreaks in both wild and domestic bird populations. Notably:

• The United States has seen continued detections in wild birds across all 50 states, with significant impacts on commercial poultry farms, particularly in the Midwest and Pacific Northwest.
• Europe experienced a surge during the winter migration season, with France, Germany, and the UK reporting large-scale culling operations to contain spread.
\li>Canada has issued alerts in provinces including British Columbia, Quebec, and Ontario due to confirmed cases in backyard flocks and migratory waterfowl.
• Asia continues to monitor endemic circulation in countries like China, Vietnam, and India, where live bird markets increase transmission risk.

These outbreaks are closely tied to bird migration routes, especially along major flyways such as the Atlantic, Mississippi, Central, and Pacific Flyways in North America. Seasonal movements amplify geographic spread, particularly during spring and fall migrations.

Transmission and Risk Factors

Bird flu spreads primarily through direct contact between infected and healthy birds, as well as via contaminated environments. Key transmission pathways include:

• Fecal-oral route: Infected birds shed the virus in feces, saliva, and nasal secretions.
• Contaminated surfaces: Equipment, clothing, feed, water sources, and cages can harbor the virus.
• Airborne particles: In dense poultry facilities, aerosolized droplets may contribute to rapid transmission.
• Predation/scavenging: Mammals that consume infected birds (e.g., foxes, raccoons, skunks) can become exposed, though sustained mammalian transmission remains rare.

Human infections remain uncommon but are possible, typically occurring after prolonged, close contact with sick or dead birds—especially in occupational settings like poultry farming or veterinary work. Most human cases linked to H5N1 have occurred in Asia and Eastern Europe, with limited person-to-person transmission documented only in isolated instances.

Symptoms in Birds and Humans

In birds, clinical signs vary by species and strain virulence. Common symptoms include:

• Sudden death without prior signs
• Decreased food and water intake
• Ruffled feathers and lethargy
• Swelling of the head, eyelids, comb, wattles, and hocks
• Soft-shelled or misshapen eggs
• Nasal discharge, coughing, sneezing
• Torticollis (twisted neck) or neurological disorders

In humans, symptoms resemble those of severe influenza and may progress rapidly. They include:

• Fever and chills
• Cough and sore throat
• Muscle aches and fatigue
• Headache
• Shortness of breath or pneumonia-like lung involvement
• In severe cases, acute respiratory distress syndrome (ARDS), multi-organ failure, and death

It's important to note that seasonal human flu viruses (like H1N1 or H3N2) are unrelated to avian influenza and spread easily among people. In contrast, bird flu does not currently transmit efficiently between humans, which limits pandemic risk—but vigilance is essential given the virus’s ability to evolve.

Impact on Wildlife, Agriculture, and Public Health

The ecological and economic toll of the ongoing bird flu epidemic has been substantial. Millions of commercial birds have been culled worldwide to prevent further spread, disrupting egg and poultry supply chains and contributing to price volatility. Backyard flock owners have also faced losses, prompting increased biosecurity recommendations.

Wildlife impacts are equally concerning. Unusual mortality events have been observed in raptors, seabird colonies (such as puffins and gannets), and even marine mammals like seals and sea lions, indicating broader ecosystem disruption. Conservationists worry about long-term effects on vulnerable bird populations, especially those already threatened by habitat loss or climate change.

What Should Birdwatchers Know?

For bird enthusiasts, staying safe while enjoying nature means adopting simple precautions:

• Do not touch sick or dead birds. Report them to local wildlife authorities or use official reporting apps (e.g., USGS National Wildlife Health Center).
• Maintain distance. Use binoculars or spotting scopes instead of approaching birds closely.
• Clean equipment. Disinfect boots, camera lenses, tripods, and feeders regularly, especially after visiting wetlands or farms.
• Avoid feeding waterfowl in areas with known outbreaks, as congregations increase transmission risk.
• Check regional advisories before visiting parks, refuges, or reserves. Some sites may restrict access during active outbreaks.

Protecting Pets and Livestock

Poultry keepers should implement strict biosecurity protocols:

• Isolate new birds for at least 30 days.
• Prevent contact between wild birds and domestic flocks using netting or enclosed runs.
• Change clothes and footwear before entering coops.
• Source feed from reputable suppliers and store it securely.
• Vaccinate if approved locally—though vaccines do not always prevent infection, they may reduce shedding.

Cats and dogs can rarely become infected if they eat infected carcasses. Keep pets leashed in areas where dead birds have been reported and consult a veterinarian if your pet shows respiratory or neurological symptoms after outdoor exposure.

Common Misconceptions About Bird Flu

Several myths persist about avian influenza, potentially leading to misinformation:

• Myth: Eating properly cooked poultry or eggs can give you bird flu. Fact: No. The virus is destroyed at cooking temperatures above 165°F (74°C). Proper food handling eliminates any risk.
• Myth: All migrating birds are dangerous carriers. Fact: While some wild birds carry the virus asymptomatically, not every individual is infected. Avoidance of direct contact is sufficient protection.
• Myth: There’s a human pandemic imminent. Fact: Current evidence shows no sustained human-to-human transmission. The CDC maintains the risk to the general public as low.
• Myth: Vaccines for seasonal flu protect against bird flu. Fact: They do not. Specific candidate vaccines exist for H5N1 but are stockpiled for emergency use, not routine administration.
