Summary of key features of equine influenza described in mathematical models

Feature	Reference
Equine influenza is highly contagious	Glass et al. (2002) 10
Vaccination reduces the occurrence of epidemics	de la Rua-Domenech et al. (2000) 12; Glass et al. (2002) 10
The majority of outbreaks in a vaccinated group of horses are of limited size	Glass et al. (2002) 10
Strategic timing of vaccination can reduce the risk of outbreaks occurring when horses congregate for racing or sales	Park et al. (2003) 13
Although of little consequence at the individual level, a mismatched vaccine strain increases the likelihood of larger outbreaks occurring	Park et al. (2004) 14
Effective quarantine prevents incursion of novel equine influenza strains	Koelle et al. (2010) [18]
Vaccination in the face of an outbreak is an effective control measure	Baguelin et al. (2010) 20
Individuals within a group of vaccinated animals that remain unvaccinated or respond poorly to vaccination can have serious consequences	Baguelin et al. (2010) 20
