HPAI (H5) confirmed in backyard birds in Cajamarca Department, Peru
SAT 14 MAR 2026

Key findings
  • A highly pathogenic avian influenza (HPAI) H5 virus outbreak was confirmed in backyard birds in Cajabamba District, Cajamarca Department, beginning on 02 Feb 2026, and verified by real-time PCR (polymerase chain reaction) on 05 Feb 2026, at the SENASA (National Service of Agrarian Health) Animal Health Diagnostic Center.
  • The report was communicated to the World Organisation for Animal Health (WOAH) on 12 Mar 2026.
  • All 63 susceptible birds in the affected backyard epidemiological unit died, resulting in a 100% mortality rate across domestic species, including turkeys, ducks, roosters, hens, geese, and chickens, in Pampa Chica.
  • The outbreak is a recurrence of HPAI, with the most recent case reported in Peru in August 2025, and the source of infection remains unknown or inconclusive.

Comparative analysis and future outlook
  • The outbreak reported in Cajabamba indicates ongoing high HPAI activity in Peru, where 387 outbreaks have been reported to WOAH since November 2022. These incidents have impacted backyard poultry, wild birds, and marine mammals across multiple departments, highlighting the virus’s capacity to spread through domestic, wildlife, and coastal ecosystems. The recurrence in Cajamarca indicates either continued viral circulation or repeated reintroductions, potentially linked to interactions between domestic birds and infected wildlife.
  • This outbreak also occurs within a broader regional context of ongoing circulation of H5N1 Avian Influenza across the Southern Cone and neighboring countries, including Argentina, Brazil, Chile, Colombia, and Uruguay. The persistence of the virus in this region highlights the continued epidemiological pressure in South America and emphasizes the need for coordinated surveillance and rapid information sharing among countries.
​-snip-
  • Timely communication is essential for early warning and disease control. According to international regulations, countries are required to notify the World Animal Health Information System (WAHIS) within 24 hours of significant animal health events, such as the initial occurrence or recurrence of a listed disease, the emergence of a new strain, unexpected changes in disease spread or severity, or detection in unusual host species. In this instance, the outbreak in Cajamarca was reported to the World Organisation for Animal Health about five weeks after laboratory confirmation. Delayed reporting can limit regional preparedness and response efforts; therefore, prompt and transparent communication is crucial to strengthening early warning systems and enabling rapid containment of transboundary animal diseases such as HPAI.

Lambayeque: Isolated outbreaks of avian influenza detected in backyard poultry farms

Senasa authorities confirmed at least four cases in different districts

The country maintains its avian influenza-free status in commercial farms.

23:55 | Chiclayo, May 11.

So far this year, authorities from the National Agrarian Health Service (Senasa) have confirmed at least four isolated outbreaks of avian influenza in different districts of the Lambayeque region, raising alerts among local producers, although ruling out -for now- a major risk to the formal poultry industry.

This was reported by the executive director of Senasa-Lambayeque, Félix Bobadilla Morales, who added that the cases have been detected in areas such as Pomalca, Pucalá, San José and Monsefú, and correspond to the same type of virus registered in previous years (2019 and 2021 ).

“These outbreaks are mainly linked to domestic or backyard farming, where biosecurity conditions are often limited,” he noted.

“Birds raised intensively in confined spaces, often in contact with wild birds, facilitate the spread of the virus,” Bobadilla explained. Despite this, he emphasized that the country maintains its avian influenza-free status in commercial farms, which reduces the large-scale economic impact.

In the specific case of Motupe, the authority ruled out the presence of avian influenza and specified that the mortality recorded in the area was due to another virus: infectious laryngotracheitis, a different disease that affects only birds.

However, in the Picsi sector, a new isolated case of avian influenza was confirmed, along with an outbreak of classical swine fever (CSF) in pigs.

In response to this situation, Senasa activated emergency protocols, including the declaration of quarantine, sanitary slaughter of infected animals and those in contact with them, as well as the disinfection of premises.

The Senasa authority stated that epidemiological surveillance actions have also been deployed within a 10-kilometer radius of the detected outbreaks , with the aim of preventing the spread to other livestock farms.

Despite concerns raised by reports of mass deaths of birds and other animals in some rural areas, the specialist insisted that these are isolated incidents and are currently under control. "The loss of animals has been minimal, and the outbreaks are not as severe as in previous years," he stated.

Finally, he urged the public not to sell sick animals and to immediately report any suspected cases to Senasa. “Selling infected animals could spread the disease. It is essential to comply with health measures,” he warned.

The authority also clarified that these diseases do not pose a risk to human health, but they can seriously affect the economy of families that depend on raising animals.
