Yesterday, in Austria's announcement of detecting H5N8 at Lake Constance, they mentioned they had been notified of outbreaks in Croatia along with Poland, Hungary and Germany.
Today, we have an official announcement from the Croatian Ministry of Agriculture.
In the area of Vukovar-Srijem County (village Cerna) in wild swans was found highly pathogenic avian influenza (H5 N8). The virus belongs to the glow of that so far has not been found to cause infection in humans.
Avian influenza is a highly contagious viral disease of poultry and other birds, which can manifest itself in different ways, depending on the ability of the virus to cause disease (pathogenicity) and the affected species. According to its pathogenicity (ability to cause disease) avian influenza is divided into:
- Highly pathogenic viruses IP (HPAI) spread quickly and lead to high mortality rates (up to 100% within 48 hours)
- Low pathogenic viruses IP (LPAI) generally cause mild symptoms and can easily go undetectedFrom poultry usually get sick chickens and turkeys, and the ducks and geese to develop mild symptoms. Wild birds that live along the water, notably wild ducks, are naturally resistant to disease and show no clinical signs of disease and therefore represent a reservoir of the virus and a major threat to the spread of the disease to domestic poultry. The infection in birds and poultry spreads through respiratory tract discharge, feces, carcasses of dead birds. Feces infected birds contains a high concentration of the virus so that it can contaminate water, equipment, feed, bedding, means of transport, and all that comes into contact with such feces, so the possibility of horizontal transfer large.
According to the current legislation, the obligations of owners of animals (every legal or natural person who as owner, user or screen directly responsible for animal health) the application suspicion veterinarian. In case of noticing a large number of deaths of wild birds, please contact your local veterinarian or the Veterinary and food safety on e-mail: Veterinary @ mps.hr . We invite owners of poultry to responsible behavior and adherence to biosecurity measures to prevent the entry of infectious agents in domestic poultry.
Any new information the public will be duly informed.
