FIG 4.

The effects of lagged PM10 and temperature on the number of Valley fever cases. A 2-month lag time before the month where cases were reported was employed. (A) Simulation of predicted Valley fever cases across the entire range of lagged PM10. Red means that there is a strong effect of maximum temperatures and Valley fever infections, and blue indicates a weak effect of PM10 on Valley fever infections. (B) Raw lagged PM10 data plotted against monthly Valley fever data added together from all three counties. LOESS smoother line used in order to visualize relationships.
