Bird flu

Bird flu, or avian influenza, is a disease impacting poultry and other birds, caused by influenza virus variants that are highly contagious among birds. The virus mainly occurs in birds, but in some cases it can also infect humans. This usually happens through direct contact with infected animals or their droppings.

For organisations with employees who travel internationally or work in environments involving animals, agriculture or food production, avian influenza is a relevant health risk.

Where does bird flu occur?

Bird flu is present worldwide. The Netherlands serves as a crucial stopover for migratory birds, with nearly all of them stopping or flying over the country. This involves hundreds of millions of birds annually, potentially carrying and introducing new bird flu variants.

What are the symptoms?

Avian influenza in humans is rare. People who become infected with an avian influenza virus experience symptoms similar to those of common flu, such as:

• Fever
• Headache
• Muscle pain
• Cough
• Shortness of breath

In severe cases, avian influenza can lead to pneumonia or other complications. Early recognition and medical assessment are therefore important, especially for employees who travel for work.

How can you prevent bird flu?

Bird flu can occasionally transfer from animals to humans, known as zoonosis, typically after close contact with sick birds, such as in poultry farming or handling dead birds. It is advised to avoid contact with dead birds.

Currently, no specific vaccine exists for bird flu due to the numerous and rapidly changing virus subtypes. People working closely with potentially sick animals may receive antiviral medications to lower the risk of illness.
