Dengue generated over a million Google search queries every month. Some queries showed that the user was looking for more information about the disease, while others were looking for symptoms or treatments. Model-fitted 'expected' epidemic curves matched official case counts 'observed' epidemic curves quite well for all 5 countries in most countries (Fig. 1) , with validation correlations ranging from 0.82 to 0.99. Dengue queries were not as influenced by mass panic-induced searching.
