The presence of live bird markets and live bird trade in many countries has made control of AI harder. Live bird markets can act as viral reservoirs to maintain and increase the spread of the disease, both through fomites and movement of infected birds.  This increase in circulation can aid the development of more, potentially zoonotic, strains. Fragmenting the live bird market network through disinfecting both the market (daily) and the vehicles coming in and out would greatly reduce the spread. The concept of ‘rest days’ to limit spread has also been introduced in some areas. Previously a ban on live bird markets has only served to result in illegal bird markets, which have resulted in further spread of AI both due to the lack of knowledge of where these were taking place and the lack of control over biosecurity. Education of the local population plays a key role in the reduction of the spread of AI. Bioexclusion (excluding the virus) in farms and villages should be the aim, whereas biocontainment (containing the virus) should be the aim with markets.

==Vaccination==

===Vaccination===

Vaccination against AI is usually only used in order to help control an outbreak. A majority of the vaccines used are inactivated vaccines, though some are starting to use vectored vaccines.  A reverse genetic engineered reassortant (rg) vaccine is also available. This vaccine has been updated twice due to changing field viruses.
