Using Web Search Query Data to Monitor Dengue Epidemics: A New Model for Neglected Tropical Disease Surveillance
Figure 1
A comparison of the model-fitted and official case counts dengue epidemic curves in each country.
The model-fitted epidemic curve as compared to the official case counts epidemic curve for dengue in each of the five countries for which a model built on Google search volume data was developed. Bolivia and Singapore are shown at a weekly resolution, the others on a monthly resolution. The activity index is a scaled measure of the case counts, representing the relative amount of dengue activity in each country on a scale from 0 to 100. Shaded regions indicate the season held out for testing the final models.
