Figure 2. Estimated smoothed hazard of IAV infection over the number of hours since the origin of the fair for individual pigs at risk at 6 IAV-positive agricultural fairs, Ohio and Indiana, USA, 2014 and 2015. All 6 IAV-positive fairs from our longitudinal study are shown individually. Overall, hazard estimates increase throughout the duration of the fair. The exceptionally low hazards for fair 14E correspond to the low incidence of IAV documented in Figure 1 and Appendix Table 1 (https://wwwnc.cdc.gov/EID/article/28/10/22-0649-App1.pdf). IAV, influenza A virus.
