dc.description.abstractH9N2 avian influenza viruses (AIVs) are a major concern for the poultry sec24 tor and human health in countries where this subtype is endemic. By fitting a 25 model simulating H9N2 AIV transmission to data from a field experiment, we 26 characterise the epidemiology of the virus in a live bird market in Bangladesh. 27 Many supplied birds arrive already exposed to H9N2 AIVs, resulting in many 28 broiler chickens entering the market as infected, and many indigenous back29 yard chickens entering with pre-existing immunity. Most susceptible chickens 30 become infected within one day spent at the market, owing to high levels of 31 viral transmission within market and short latent periods, as brief as 5.3 hours. Although H9N2 AIV transmission can be substantially reduced under moderate 33 levels of cleaning and disinfection, effective risk mitigation also requires a range 34 of additional interventions targeting markets and other nodes along the poultry 35 production and distribution network.eng
