We compared the number of confirmed influenza A and B cases in SEDSS to virologic surveillance data collected by US WHO and To explore if differences in seasonality between Puerto Rico and HHS regions were due to differences in climate, we obtained regional climate data (absolute humidity, temperature and precipitation) from 2012 to 2018 from the North American Regional Reanalysis data set from the National Oceanic and Atmospheric Administration (NOAA). In terms of the overall time series climatic trends, Puerto Rico was consistently warmer and more humid over the time series compared with weekly average absolute humidity and temperature in HHS regions (Figure 2A 19, 20 and epidemiological studies showed lower humidity is associated with the onset of influenza epidemics in the United	./cache/cord-311884-3lkkpg9g.txt	./txt/cord-311884-3lkkpg9g.txt
