  In this paper, the motility model for the developed country, which United
State possesses the largest economy in the world and thus serves as an ideal
representation, is investigated. Early surveillance of the causes of death is
critical which can allow the preparation of preventive steps against critical
disease such as dengue fever. Studies reported that some search queries,
especially those diseases related terms on Google Trends are essential. To this
end, we include either main cause of death or the extended or the more general
terminologies from Google Trends to decode the mortality related terms using
the Wiener Cascade Model. Using time series and Wavelet scalogram of search
terms, the patterns of search queries are categorized into different levels of
periodicity. The results include the decoding trend, the features importance,
and the accuracy of the decoding patterns. Three scenarios regard predictors
include the use of all 19 features, the top ten most periodic predictors, or
the ten predictors with highest weighting. All search queries spans from
December 2013 - December 2018. The results show that search terms with both
higher weight and annual periodic pattern contribute more in forecasting the
word die; however, only predictors with higher weight are valuable to forecast
the word death.
