According to the Food and Veterinary Service (PVD), public reporting of dead wild birds is essential for tracking the spread of West Nile virus in Latvia. While laboratory testing of 36 dead wild birds through September revealed no positive cases locally, European neighbors have reported detections in both wild avian populations and horses this season, prompting heightened surveillance.
Where and How to Report Dead Birds in Latvia
Citizens can report findings of dead wild birds directly to regional PVD offices. Reports and drop-offs should specify that the specimen is submitted for complimentary West Nile virus screening under the "OH4S" project framework.
Safety Precautions for Handling Carcasses
Handling wildlife requires strict biosecurity measures to prevent potential zoonotic transmission. According to PVD safety guidelines, anyone handling a dead bird must wear disposable gloves and seal the remains inside two separate water-resistant plastic bags before transport to a regional “BIOR” sample collection point.
Understanding West Nile Virus Risks
West Nile virus is a zoonotic infection capable of affecting both humans and animals. According to health authorities, mosquitoes serve as the primary vectors for transmission, while wild birds—particularly corvids such as crows, magpies, and sparrows—act as the main natural virus reservoir.
Did you know? The first confirmed case of West Nile virus in Latvia’s history was recorded in the autumn of 2024, when the pathogen was detected in a deceased northern goshawk.
The Role of the “OH4S” Project
Research into the virus’s circulation across local wildlife is backed by the European Union under the “One Health 4 Surveillance” project. According to project records, authorities conducted 424 laboratory tests in 2025 across dead or symptomatic wild birds, horses displaying clinical signs, and pooled mosquito samples, with no positive detections found.
Frequently Asked Questions
Which bird species are most susceptible to West Nile virus?
According to the PVD, corvids such as crows, magpies, and sparrows are primary targets for surveillance and act as the main natural virus reservoirs.
Is bird testing for West Nile virus free of charge?
Yes. Laboratory testing conducted at the "BIOR" institute under the "OH4S" project is provided free of charge when properly identified upon delivery.
Can humans contract West Nile virus directly from dead birds?
The virus is primarily transmitted by mosquitoes, but handling infected wildlife without proper protection like gloves and sealed bags poses potential risks, making safety protocols mandatory.
