The Tourism and Health Information System (THiS) is a web-based application for syndromic surveillance of populations in tourist accommodations THiS.carpha.org. This real time, early warning system is confidential and only accessible by national authorities. It is currently being implemented in hotels and guest houses in 8 countries (Bahamas, Barbados, Belize, Guyana, Jamaica, Trinidad & Tobago, Bermuda and Turks & Caicos Islands).
The THiS web app was designed to enhance national surveillance systems by monitoring illnesses in tourist accommodations to identify public health threats early. Figure 1 shows a schematic of how the THiS web app integrates into the existing national and regional public health surveillance mechanisms.
