CATDOLL : CATDOLL: Transmission routes and prevention measures of avian influenza in poultry

How avian influenza spreads in poultry

Avian influenza is a viral disease that infects poultry and can be transmitted to poultry in a variety of ways. The most common routes of transmission include:

• Direct contact transmission: When healthy poultry come into contact with poultry infected with avian influenza, the virus can be transmitted through touch, shared water, feed and the environment.
• Respiratory transmission: Avian influenza virus can be transmitted to surrounding poultry through droplets and aerosols.
• Indirect transmission: Humans, tools, vehicles and other potentially infected objects come into contact with the avian influenza virus and then come into contact with poultry, thereby spreading the virus.
• Vertical transmission: Avian influenza viruses in infected hens can be passed on to the next generation of poultry through eggs.

Preventive measures for avian influenza in poultry

To prevent avian influenza in poultry, we need to take a series of measures to reduce the risk of virus transmission:

• Improve poultry farm management and hygiene:
  • Keep the breeding environment clean and sanitary, and clean up feces and debris regularly.
  • Access to poultry farms is strictly controlled, and visitors are closely monitored.
  • Strengthen ventilation and disinfection of poultry houses.
• Strengthening biosecurity measures in poultry farming:
  • Strictly limit contact with other birds and avoid close proximity of wild birds and domestic poultry.
  • Strictly control the disinfection of transportation vehicles, and regularly inspect and clean facilities.
  • Ensure the environment around the farm is clean to prevent the virus from spreading through sewage and other channels.
• Standardize feeding management and feed supply:
  • Use feed and additives rationally to ensure that poultry have a balanced diet and adequate nutrition.
  • Check the quality of feed regularly and prevent it from being contaminated or moldy.
• Prevention and control of avian influenza outbreaks in poultry:
  • Vaccinate poultry regularly and dispose of sick and dead poultry promptly.
  • Report the epidemic in a timely manner and take isolation measures to prevent the spread of the epidemic.

Through the implementation of the above measures, we can effectively prevent and control the spread of avian influenza in poultry and reduce the economic and health losses caused by the virus.
