Avian Influenza: A Global Threat to the Poultry Industry

Avian influenza affects birds worldwide, caused by various subtypes of the influenza A virus. This virus is characterized by its genetic variability, presenting a wide range of hemagglutinin and neuraminidase subtypes. However, within this diversity, two classifications stand out for their relevance:

• High pathogenic avian influenza virus.
• Low pathogenic avian influenza virus.

Highly pathogenic avian influenza viruses are of concern because of their ability to cause severe disease and high mortality rates in infected birds. These viruses can cause rapidly devastating outbreaks in poultry populations, resulting in significant economic losses to producers.

On the other hand, low pathogenic avian influenza viruses generally cause milder disease or may even go unnoticed. Although their direct impact may be less severe than that of their highly pathogenic counterparts, these viruses still pose a threat to the poultry industry, as they can serve as containers for genes that can combine with other influenza viruses such as human or swine influenza, giving rise to potentially dangerous new strains.

• But how can we prevent or manage it?

Well, the prevention of avian influenza is crucial to protect poultry populations and avoid significant economic losses in the industry. Therefore, Zucami would like to provide our readers with some key points to keep in mind:

1. Rigorous Biosecurity

Implementing adequate biosecurity measures at all stages of poultry production is critical. This includes limiting access of unauthorized persons to the facilities, the use of exclusive equipment and tools for each area, and regular disinfection of facilities and equipment.

2. Control of Bird Movements

Restricting bird movements and preventing the entry of birds from areas with known outbreaks of avian influenza can help prevent the introduction and spread of the virus into poultry populations.

3. Epidemiological Surveillance:

Establishing epidemiological surveillance programs to detect the presence of the disease in early stages is essential.

4. Vaccination

In some regions, selective vaccination programs against specific strains of avian influenza can be implemented, especially in high-risk areas. However, it is important to remember that vaccination is not a substitute for other prevention and control measures.

5. Education and Training

Training personnel in proper handling and biosecurity practices, as well as in the recognition of clinical signs of disease, can help prevent the spread of avian influenza within poultry facilities.

6. Collaboration and Coordination

Working closely with health authorities, industry organizations and other relevant stakeholders can facilitate the coordination of efforts to prevent and control avian influenza outbreaks.

In conclusion, avian influenza represents a constant threat to the global poultry industry. Early detection, implementation of rigorous biosecurity measures, epidemiological surveillance, vaccination, continuous education and collaboration with the different agencies in each country are fundamental to mitigate the risks associated with this disease. At Zucami, we are committed to providing our customers with
the tools and knowledge necessary to meet this global challenge and protect the health and sustainability of their poultry operations.
