Since the beginning of the year, there have been outbreaks of highly pathogenic avian influenza (HPAI) in Eastern Europe and Germany, leading to concerns in Switzerland. The Office of Food Safety and Veterinary Affairs (FSVO) has highlighted the need for biosecurity measures to protect Swiss poultry. HPAI can cause symptoms like breathing difficulties, reduced laying performance, and high mortality in productive birds, while waterfowl may carry the virus without showing symptoms. LPAI infections can mutate into HPAI and spread through inhalation of contaminated droplets or dust. No cases of HPAI in productive poultry in Switzerland since the 1930s. The FSVO prohibits the importation of poultry and poultry products from countries with HPAI, and regulates free-range breeding operations. The disease can also affect humans, causing symptoms similar to the flu.
