Figure 1. Screenshot of search performed on the term “pneumonia” using the Google Insights for Search tool (http://www.google.com/insights/search/#).
The expected wintertime seasonality of pneumonia incidence is mirrored in seasonal surges in search volumes.
Figure 2
Figure 2. Screenshot of search performed on the term “influenza” using the Google Insights for Search tool (http://www.google.com/insights/search/#).
Although influenza searches would expect to display similar wintertime seasonality to pneumonia searches, depicted in Figure 1, the public concern and interest generated by the 2009 influenza pandemic generated a large spike in searches in that year, which obscures seasonal oscillation in other years.
