Figure 1.

Epidemic curves for the 2016/2017 chimpanzee respiratory disease outbreaks at Ngogo (top) and Kanyawara (bottom) communities in Kibale National Park, Uganda. Dotted lines indicate 2017 mean rates of respiratory signs (lower line) and 2 standard deviations above the mean (upper line). Asterisks above bars indicate the estimated timing of individual mortality events attributed to respiratory disease. The grey box in the lower graph represents dates with missing data (no clinical signs were observed at Kanyawara before this period).
