Risk of poultry compartments for transmission of Highly Pathogenic Avian Influenza
Fig 3
Reproduction number R0,m of VPI compartment farms, when all transmission probabilities of the contact types of Table 1 are reduced with a certain percentage, due to improvement of biosecurity measures within the compartment.
A biosecurity improvement of 0% represents the biosecurity status of poultry farms during the HPAI epidemic in the Netherlands in 2003. A biosecurity improvement of 100% is a purely fictitious scenario of perfect biosecurity leading to zero risk.
