Figure 4. Epidemiologic regions of scrub typhus in China, 2006–2016. A) Epidemiologic regions based on hierarchical clustering, using the Pearson correlation coefficient matrix between average weekly scrub typhus time series of paired provinces that had a cumulative number of cases >100 in 2006–2016 combined. B) Map of identified epidemiologic regions identified by hierarchical clustering), e.g., middle-east (latitude range 31°–41°N and longitude range 105°–125°E), southwest (latitude range 21°–31°N and longitude range 95°–105°E), southeast of China (latitude range 21°–31°N and longitude range 105°–125°E). Other provinces had a combined total of <100 cases in 2006–2016.
