We suspect that AI virus spread among many egg-laying farms by this means. Certain countries have required vaccinations. All trucks and equipment leaving a facility should be cleaned and disinfected before exiting the facility if suspect or positive flocks are present. Safe and effective vaccines are available and have been used for more than 60 years. Many of the practices involved in the modern production of poultry also support the spread and amplification of disease agents such as AI virus. However, the influenza A viruses can adapt to the new host species through circulation as low-level infections within a population and, through random mutations in the viral genome, gradually adapt to the new species with increased efficiency of replication and transmission.

Prevention and Treatment of Avian Influenza A Viruses in People
The first part of the plan required participants to minimize the risk of exposure with the following biosecurity practices: AI control strategies are designed to achieve one of three goals or outcomes Swayne and Akey, Department of Agriculture, Agriculture Research Service, Southeast Poultry Research Laboratory, Athens, Georgia Abstract Strategies to control avian influenza virus are developed to prevent, manage, or eradicate the virus from a country, region, state, county, or farm. Because of the mingling of intercontinental avifaunas, this area is most likely to harbor host switching and genetic reassortment among AI viruses from Asia and the Americas.
