Correction: Nation-Wide, Web-Based, Geographic Information System for the Integrated Surveillance and Control of Dengue Fever in Mexico

Abstract

Dengue fever incidence and its geographical distribution are increasing throughout the world. Quality and timely information is essential for its prevention and control. A web based, geographically enabled, dengue integral surveillance system (Dengue-GIS) was developed for the nation-wide collection, integration, analysis and reporting of geo-referenced epidemiologic, entomologic, and control interventions data. Consensus in the design and practical operation of the system was a key factor for its acceptance. Working with information systems already implemented as a starting point facilitated its acceptance by officials and operative personnel. Dengue-GIS provides the geographical detail needed to plan, asses and evaluate the impact of control activities. The system is beginning to be adopted as a knowledge base by vector control programs. It is used to generate evidence on impact and cost-effectiveness of control activities, promoting the use of information for decision making at all levels of the vector control program. Dengue-GIS has also been used as a hypothesis generator for the academic community. This GIS-based model system for dengue surveillance and the experience gathered during its development and implementation could be useful in other dengue endemic countries and extended to other infectious or chronic diseases.

Early warning and response system for dengue outbreaks: Moving from research to operational implementation in Mexico

“…With the support of the National Institute of Public Health, the "Comprehensive Vector Monitoring System, in the information subsystem for dengue surveillance" was launched, it is worth mentioning that this platform has been improved over the years for the benefit of the user (the operational and analytical personnel), which facilitated the opportunity of linking confirmed geo-referenced cases with ovitraps indicators such as the proportion of positive ovitraps and average number of Aedes eggs per block of houses. This led to the generation of the "Transmission Risk Indicator", where the areas of greatest risk are those blocks (or clusters) with the highest number of vector eggs and the highest number of cases [9].…”

Insecticide-Treated House Screens to Reduce Infestations of Dengue Vectors

“…Intervention clusters included insecticidetreated window and door screens (Acapulco and Merida) and targeted interventions in the productive water container types (in Acapulco only). As part of the national policy in response to dengue outbreaks and entomological risk indices [37], control and ITS intervention clusters could receive routine vector control activities (outdoor spraying with the organophosphates malathion or chlorpyrifos, indoor space spraying with the pyrethroid deltamethrin or the carbamates propoxur or bendiocarb and larviciding with the organophosphate temephos).…”
