  • Avian Influenza is caused by a zoonotic virus that occurs in lower animals and birds as well as in humans.
  • Influenza viruses belong to the Orthomyxoviridae family of RNA viruses and are constituted of four genera. Influenza virus A, B, C and Thogoto virus. These viruses have segmented negative-strand RNA genomes.
  • In lower animals and birds influenza A viruses are of primary concern while influenza B virus has been reported in seals and influenza C virus in swine. So far Avian Influenza epidemics were reported from 63 countries.
  • Avian Influenza is a highly contagious generalized viral disease that may cause high mortality in gallinaceous species of birds in association with respiratory, gastrointestinal & or nervous signs.
  • Wild aquatic birds like water fowl, ducks, swans,Gheese & shore birds acts as important reservoirs for avian influenza virus. Avian Influenza virus infection may range clinically from an inapparent to a highly lethal disease.
  • Wild aquatic birds like water fowl, ducks, swans,Gheese & shore birds acts as important reservoirs for avian influenza virus. Avian Influenza virus infection may range clinically from an inapparent to a highly lethal diseaseSubtypes based on surface proteins- Haemagglutin & Neuraminidase proteins are present on the surface of virus which undergo genetic changes by process of antigenic shift & drift.
  • The following subtypes are identified till today are Haemagglutinin-'H-1 to H-16' & Neuraminidase- 'N-1 to N-9' out of which H5 & H7 – are highly pathogenic, without showing clinical signs, 100% mortality in birds.

    • Routes of bird-to-bird transmission include :

    • Airborne transmission if birds are in close proximity.
    • Direct contact with contaminated respiratory secretions or fecal material.
    • The virus multiplies in the intestines of these birds and is shed in saliva, nasal secretions and feces.
    • A single gram of contaminated feces contains enough virus to infect 1 million birds.
    • Birds that survive infection excrete virus for at least 10 days, orally and in feces, thus facilitating further spread.

    Clinical Signs-

  • Sudden death -High Mortality, Lack of energy and appetite, Swelling of head, eyelids, comb, wattles and legs, Purple discoloration of the wattles and combs, Nasal discharge, Coughing and sneezing, Diarrhea.

    • P.M.Lesions-

  • Congestion & various degrees of hemorrhages in URS (larynx & trachea): trachietis Hemorrhages in porventriculus, Liver, Thigh muscles & Spleenomegally.

    • Control Measures-

  • Disease may spread by different means and therefore following measures may be adopted for control of disease.
  • Strict sanitary & Biosecurity as well as Hygienic measures may be taken.
  • Control of Wild/migratory birds.
  • Rapid and careful disposal of carcasses of dead birds is essential. For disposal of birds use burning or burial method.
  • Strict control on movement of poultry & poultry by products.
  • Routine Sero-Surveillance, Collection of Cloacal/Nasal/Throat swabs.
  • Strict decontamination, through cleaning and disinfection.
