Bird flu


When it comes todead birds, diseases of chickens and hens, one cannot help but stumble upon the wordavian. L'bird fluit returns to Italy periodically decimating poultry farms.

Avian flu: meaning

L'avianit's aviral diseasewhich concerns certainpoultry species, both farmed and wild. Thisinfectious diseaseit does not know geographic discrimination and can affect the whole national territory.

How do you take the avian? Just like the flu that attacks humans by contagion. The virus it can be moved from one area of ​​Italy to another through the movement of the poultry reared or following the migration of wild animals.

Themeaningof the name derives from the Latinavis - bird. This disease, for its target, is also known asavian plague.

Avian in Italy

Avian is a virus that causes flupandemicsin animals, just likeswine feverorswine flu.

When it comes to the virus ofbird fluin fact, several viruses are referred to because there are severalmutations. The so-calledserotypesthey arise from mutations of the original virus. Mutations are rapid and frequent. THEavian flu serotypesthey can behighly pathogenicor alow pathogenicity. In the first case, the virus would cause high mortality rates and great damage to poultry farms. In case of a low pathogenic virus, minor problems would be encountered.

In Italy theavianarrived in the nineties but did not get much talk about itself until 2005. In fact, at the end of the nineties, epidemicslow pathogenic avian influenza.

In 2005, however, the first highly pathogenic outbreaks occurred, leading to the death of hundreds of thousands of birds. Although security measures were taken at the time to limit the epidemic, still today, after some time, there are small outbreaks of avian flu scattered in various areas of the nation.

Bird flu: symptoms

Unfortunately there are nonesymptomswarning: sudden death of the animal occurs. THEsymptomsthey are rarer.

When isymptomsappear are borne by the respiratory system: difficulty in breathing, avicular head extended on the neck, oculo-nasal discharge, loss of appetite, anorexia, ruffled feathers ... the animal becomes sedentary and stops eating.

Avian in humans

In 1997 it was shown that theavian flu virusit can attack man. Yes, but which virus? As stated, there are many serotypes, plus the contagion between animals and humans is not always taken for granted.

The cases of contagion affecting humans date back mainly to 2005, in China, due to poor hygiene conditions and close contact betweeninfected poultry, man and pigs. Thus the same virus caused the infection in humans and among thepigs.

In humans, avian flu has symptoms similar to the classicseasonal flu, therefore:

  • cough
  • sneezing
  • headache
  • muscle aches
  • temperature…

In the case of more pathogenic strains, theavian flu virusit can also be fatal for humans.

Farms at risk

Thefarms at riskthey are the intensive ones. Overcrowding and stress are risk factors that make a herd prone to contractingavian virus.

Due to these characteristics, intensive farms can see more frequent outbreaks than extensive farms or small (low intensity) farms.

Despite this incidence, cases ofbird flubetweenchickensreared in the home. Of course, garden-raised chickens are less at risk but they are not immune toavian.

Forprevent avian fluMonitoring plans are carried out every year. What do they consist of? Sampling checks of agricultural farms by taking biological material to be analyzed. Typically, spot checks are done by taking samples identified from the highest risk farms.

Reporting to the ASL

As a rule, even those who breedchickensin the home should provide to report thefamily breedingto the relevant ASL. By law, in fact, every chicken coop must be registered with the health authorities.

How to do? Just go to the relevant ASL, at the veterinary section and fill out the appropriate form. No special documents are required: only personal data, location of thechicken coopand number of animals held. The type of poultry farming (hens, ducks, geese, turkeys…) must also be indicated. It is necessary to report to the ASL even if you have a singlehenin the garden!
