Over two hundred health awareness events take place in the United States in order to educate the public about various diseases. It would be informative and instructive for the organizations to know the impact of these events, although such information could be difficult to measure. We investigated whether 46 selected events attract the public attention by increasing the search frequencies of certain keywords. Internet search data from 2004 to 2017 were downloaded from Google Trend (GT). Three statistical methods including Transfer Function Noise modeling, Wilcoxon Rank Sum test, and Binomial inference were conducted. Our study showed that 10 health awareness events resulted in increased search frequencies in the event months, and 28 events did not, with the rest being classified as unclear.
