Supports targeted FMD surveillance in pigs during outbreaks; leaves open validation of transmission dynamics in prospective studies.
Nishiura et al. (2010) conducted an observational in Foot-and-mouth disease (n=292). Pig herds vs. Cattle herds was evaluated on Infection with foot-and-mouth disease (OR 4.3, 95% CI 3.2, 5.7). Pig herds were significantly more likely to be infected with foot-and-mouth disease than cattle herds (36.4% vs 8.5%; OR 4.3, 95% CI 3.2-5.7).
