Avian influenza poses an increasing problem in Europe and around the world. Simulation models are a useful tool to predict the spatiotemporal risk of avian influenza spread and evaluate appropriate control actions. To develop realistic simulation models, valid transmission parameters are critical. Here, we reviewed published estimates of the basic reproduction number (R0), the latent period and the infectious period by virus type, pathogenicity, species, study type and poultry flock unit. We found a large variation in the parameter estimates, with highest R0 estimates for H5N1 and H7N3 compared with other types; for low pathogenic avian influenza compared with high pathogenic avian influenza types; for ducks compared with other species; for estimates from field studies compared with experimental studies; and for within‐flock estimates compared with between‐flock estimates. Simulation models should reflect this observed variation so as to produce more reliable outputs and support decision‐making. How to incorporate this information into simulation models remains a challenge.

“…This is particularly the case in the United States, where the Muscovy duck is legally recognized as an invasive species due to threats it poses to other species and the environment (USFWS 2010). Some of these potential concerns include: interbreeding with wild waterfowl (Brun et al 2012), competition for resources with native wildlife (USFWS 2010), degradation of water quality , and transmission of various diseases to native birds and domestic poultry (Takahashi et al 1996, Lvov et al 2008, Zhu et al 2012, Niqueux et al 2014, Yun et al 2014. Accordingly, the species is exempt from protection by the Migratory Bird Treaty Act in the United States (16 U.S.C.…”

“…Future studies could include updated or a variety of estimates to explore this further. The virus subtype H5N1 was almost exclusively classified as HPAI among the studies included, with the only exception being an experimental study by Niqueux et al (2014) in ducks. Thus, H5N1…”

“…Claes et al (2013) compared two virus strains (LPAIV H5N2 and H7N1) in an experimental study of chickens and found substantial differences in the transmission rate and infectious period between the two subtypes. Likewise, Niqueux et al (2014) quantified the transmission of four H5 LPAI strains in Muscovy ducks and found large differences in transmission between strains.…”

AimsOutbreaks of avian influenza in poultry farms are currently increasing in frequency, with devastating consequences for animal welfare, farmers and supply chains. Some studies have documented the direct spread of the avian influenza virus between farms. Prevention of spread between farms relies on biosecurity surveillance and control measures. However, the evolution of an outbreak on a farm might vary depending on the virus strain and poultry species involved; this would have important implications for surveillance systems, epidemiological investigations and control measures.Methods and ResultsIn this study, we utilized existing parameter estimates from the literature to evaluate the predicted course of an epidemic in a standard poultry flock with 10,000 birds. We used a stochastic SEIR simulation model to simulate outbreaks in different species and with different virus subtypes. The simulations predicted large differences in the duration and severity of outbreaks, depending on the virus subtypes. For both turkeys and chickens, outbreaks with HPAI were of shorter duration than outbreaks with LPAI. In outbreaks involving the infection of chickens with different virus subtypes, the shortest epidemic involved H7N7 and HPAIV H5N1 (median duration of 9 and 17 days, respectively) and the longest involved H5N2 (median duration of 68 days). The most severe outbreaks (number of chickens infected) were predicted for H5N1, H7N1 and H7N3 virus subtypes, and the least severe for H5N2 and H7N7, in which outbreaks for the latter subtype were predicted to develop most slowly.ConclusionsThese simulation results suggest that surveillance of certain subtypes of avian influenza virus, in chicken flocks in particular, needs to be sensitive and timely if infection is to be detected with sufficient time to implement control measures. The variability in the predictions highlights that avian influenza outbreaks are different in severity, speed and duration, so surveillance and disease response need to be nuanced and fit the specific context of poultry species and virus subtypes.
