Yes, Bird Flu Is Still Around in 2024

Yes, the bird flu is still around in 2024, with ongoing outbreaks affecting both wild birds and commercial poultry operations across multiple continents. Avian influenza, particularly the highly pathogenic H5N1 strain, continues to circulate widely, leading to significant mortality in bird populations and prompting continued surveillance by global health organizations such as the World Organisation for Animal Health (WOAH) and the Centers for Disease Control and Prevention (CDC). This persistent presence of bird flu has implications not only for animal health but also for human public health, agriculture, and birdwatching practices.

Understanding Bird Flu: A Biological Overview

Bird flu, or avian influenza, refers to a group of influenza viruses that primarily infect birds. These viruses are categorized into two main types based on their pathogenicity: low pathogenic avian influenza (LPAI), which typically causes mild symptoms in birds, and high pathogenic avian influenza (HPAI), which can spread rapidly and cause severe disease and high mortality rates among infected flocks.

The H5N1 subtype of HPAI has been particularly concerning since its emergence in Asia in the late 1990s. Over time, this virus has evolved into multiple genetic clades and has demonstrated an increasing ability to infect a broader range of bird species, including waterfowl, shorebirds, raptors, and even scavengers like vultures. In recent years, scientists have observed unprecedented geographic spread, with outbreaks reported across North America, Europe, Africa, and parts of South America.

In 2024, surveillance data from the U.S. Department of Agriculture (USDA) and European Food Safety Authority (EFSA) confirm that H5N1 remains endemic in many wild bird populations, especially migratory species. These birds act as reservoirs and vectors, spreading the virus along flyways during seasonal migrations. As a result, new spillover events into backyard flocks and commercial poultry farms continue to occur, prompting recurring depopulation measures and trade restrictions.

Current Status of Bird Flu Outbreaks in 2024

As of mid-2024, bird flu activity remains elevated worldwide. According to the CDC, over 98 million domestic birds in the United States have been affected by avian influenza since the beginning of 2022, making it the largest animal health emergency in U.S. history. While the rate of new detections fluctuates seasonally—peaking during spring and fall migration periods—ongoing cases indicate that the virus is now established in wild bird populations rather than being an isolated outbreak.

Notably, there has been increased detection in mammals, including foxes, raccoons, seals, and even dairy cattle in several U.S. states. This interspecies transmission raises concerns about viral adaptation and potential risks to human health. Although human infections remain rare, they have occurred—mostly among individuals with direct exposure to infected birds—and some cases have resulted in severe illness.

The persistence of bird flu in 2024 underscores the need for sustained monitoring, biosecurity improvements, and international cooperation. Public health agencies continue to assess the pandemic potential of circulating strains, particularly focusing on mutations that could enhance mammalian transmission.

Impact on Poultry Industry and Food Supply

The continued presence of avian influenza poses significant challenges to the global poultry industry. Commercial chicken, turkey, and egg producers face recurring threats of infection, necessitating strict biosecurity protocols, vaccination trials (in certain countries), and rapid response culling when outbreaks occur.

In the U.S., major egg-producing states such as Iowa, Ohio, and Indiana have experienced repeated outbreaks, contributing to periodic spikes in egg prices. Consumers may notice fluctuations at grocery stores, though widespread shortages have generally been avoided due to diversified supply chains and import adjustments.

To mitigate risk, farmers are encouraged to implement comprehensive biosecurity measures, including:

• Limiting access to poultry areas by visitors and vehicles
• Using dedicated clothing and footwear for farm workers
• Preventing contact between wild birds and domestic flocks

• Regular testing and early reporting of sick birds

Backyard flock owners should also take precautions, especially if they live near wetlands or other habitats frequented by wild waterfowl. The USDA offers resources and guidance through its Animal and Plant Health Inspection Service (APHIS).

Human Health Risks and Precautions

While bird flu does not currently spread easily between humans, sporadic zoonotic infections highlight the importance of vigilance. Most human cases have occurred after close contact with infected birds—such as handling sick animals, slaughtering, or cleaning contaminated coops—without proper protective equipment.

Symptoms in humans can range from mild respiratory illness to severe pneumonia and multi-organ failure. The case fatality rate for H5N1 in humans historically exceeds 50%, although this figure is likely skewed due to underreporting of milder cases.

To reduce personal risk:

• Avoid touching dead or sick wild birds
• Report unusual bird deaths to local wildlife authorities
• Wear gloves and masks when handling poultry
• Cook poultry and eggs thoroughly (internal temperature of 165°F / 74°C)
• Follow public health advisories during local outbreaks

The CDC maintains a watch list for H5N1 and other avian influenza subtypes, and antiviral medications like oseltamivir (Tamiflu) are stockpiled for use in potential human cases.

Implications for Birdwatchers and Outdoor Enthusiasts

For birdwatchers, the ongoing bird flu situation requires awareness and responsible behavior. While the risk of contracting the virus from observing birds at a distance is extremely low, certain activities can increase exposure risk.

Best practices for safe birdwatching during active bird flu seasons include:

• Maintaining a safe distance from all wild birds, especially those appearing ill or dead
• Avoiding feeding birds in areas with known outbreaks
• Disinfecting binoculars, camera lenses, boots, and gear after outings
• Refraining from visiting poultry farms or markets immediately before or after birding trips
• Checking regional alerts via state wildlife agencies or eBird’s health notices

National parks, wildlife refuges, and conservation areas may temporarily restrict access to certain zones during outbreaks to protect sensitive species or prevent human-wildlife interaction. Always check official websites before planning visits.

Global Surveillance and Scientific Response

International collaboration plays a crucial role in tracking and responding to avian influenza. Organizations such as WOAH, the World Health Organization (WHO), and the Food and Agriculture Organization (FAO) coordinate global surveillance efforts, sharing genetic sequence data and epidemiological reports in near real-time.

Genomic sequencing has revealed that the current H5N1 lineage belongs to clade 2.3.4.4b, which emerged around 2020 and exhibits enhanced environmental stability and host range expansion. Scientists are closely monitoring for key mutations—such as changes in the hemagglutinin protein—that could improve binding to mammalian receptors.

Vaccination of poultry is used in some countries (e.g., China, Egypt), but challenges remain regarding vaccine efficacy, regulatory approval, and interference with surveillance programs. In the U.S., vaccination is not yet widely deployed but is under active evaluation.
