In a recent announcement by the World Health Organization (WHO), it has been reported that five people in Europe have died due to a bacterial infection known as parrot fever. The disease is caused by a bacteria called Chlamydia psittaci (C. psittaci), which is often carried by birds.

According to the U.S. Centers for Disease Control and Prevention (CDC), exposure to both wild and domestic birds was reported in most of the cases. Individuals who work with pet birds, poultry workers, veterinarians, pet bird owners, and gardeners in areas where C. psittaci is prevalent in the native bird population are particularly susceptible to the illness.

The affected countries are currently conducting investigations into the cases, including analyzing samples from wild birds that were initially collected for avian influenza testing. WHO reiterated its commitment to monitoring the situation and assessing the risk, stating that the current risk posed by this event is considered low based on available information.

While parrot fever is a rare condition in the United States, with only about 10 reported cases per year, it can easily spread among birds when they are in close contact or confined in small spaces, according to experts. Not all infected birds show symptoms, but most exhibit behavioral changes including reduced appetite, lethargy, weight loss, ocular discharge, diarrhea, and breathing difficulties.

It is crucial to note that parrot fever is a zoonotic disease, meaning it can be transmitted from infected birds to humans. Most people are exposed to the bacteria by inhaling airborne dust particles from infected birds' droppings and respiratory secretions or through direct contact with the birds. Individuals at highest risk include bird owners, pet shop employees, poultry farm workers, and veterinarians.

Dr. Donal Bisanzio, a senior epidemiologist with RTI International, advises pet owners to have newly acquired birds or those showing symptoms examined by veterinarians specializing in bird health. Additionally, precautions should be taken when cleaning and replenishing bird feeders in areas affected by the outbreaks, as droppings left on feeders could potentially act as a source of exposure.

Although C. psittaci has been found in other small mammals such as dogs, cats, horses, and reptiles, birds are considered the primary carriers of the bacteria that can transmit the infection to humans.

As the parrot fever outbreak continues to pose a threat, health authorities are urging caution and reminding the public to remain vigilant, especially those who have frequent contact with birds. By taking necessary preventive measures, such as practicing proper hygiene and seeking veterinary care for birds displaying symptoms, the risk of contracting the infection can be minimized.
