Europe faces surge in Parrot fever cases

Parrots

An outbreak of a respiratory infection primarily affecting birds has claimed the lives of five individuals in Europe, prompting a warning from the World Health Organization (WHO). Austria, Denmark, Germany, Sweden, and the Netherlands have witnessed an unusual surge in cases of parrot fever, with nearly 90 reported cases and five fatalities between 2023 and the beginning of 2024.

Parrot fever, or psittacosis, results from the Chlamydia psittaci bacteria, commonly found in birds but capable of infecting various mammals. While human-to-human transmission is rare, individuals in close contact with birds, such as poultry workers, veterinarians, and pet-bird owners, are at a higher risk.

Symptoms of psittacosis in humans resemble the flu, including fever, chills, headache, and cough. Early antibiotic treatment is effective in curing the disease and preventing complications such as pneumonia.

The affected countries—Austria, Denmark, Germany, Sweden, and the Netherlands—have reported a significant increase in psittacosis cases, with some cases having no reported recent bird contact. Investigations are ongoing to determine whether the rise in cases is due to an actual increase in infections or improved surveillance and diagnostic techniques.

The WHO reassures that there is no evidence of human-to-human transmission within or outside the affected countries. Meanwhile, pet-bird owners are advised to maintain clean cages, avoid overcrowding, and practice proper hygiene when handling birds or their excrement. Newly acquired birds should be quarantined and promptly taken to a vet if showing signs of illness.

As the situation unfolds, authorities are conducting epidemiological investigations, and samples from wild birds are being analyzed for signs of Chlamydia psittaci infection alongside avian influenza testing. Despite the concerning increase in cases, there is currently no indication of widespread human transmission, and preventive measures for pet-bird owners remain crucial.
