Study districts across Peru (grey).
Higher elevation districts (white) excluded from analyses. Merged districts (red) were created by collapsing districts formed during the study period with their parent district(s). Base map source: GEOSS Information Exchange Data Hub, archived.

Table 1.
Descriptive statistics after merging formed districts and eliminating districts with elevation >2,500 meters (n = 701) January 2000-September 2018.
Mean was taken over district-months for outbreak weeks, temperature, and precipitation; over districts for region; and over months for El Niño variables.
Table 2.
Results from regression models, presented for each exposure of interest.
Temperature and precipitation were fit in the same model, thus each was adjusted for the other; no adjustments were made in either El Niǹo model.
