Infoveillance
Infoveillance is the type of syndromic surveillance that utilizes the online contents. The term was coined by Gunther Eysenbach in 2004 for the first time along with Infodemiology
The work of Gunther Eysenbach, which utilized the Google Search queries, had led to the birth of Google Flu. Other than Google search engines have also been used. Later other researchers utilized other social media such as Twitter to find the disease outbreak patterns. The infoveillance detects disease outbreaks quicker than traditional public health surveillance systems with the minimal cost involved, revealing the promising results for the future surveillance methodologies.
