Although local programs that use the best information and technology can be effective in curbing potential outbreaks, total eradication in regions where vector-borne diseases are endemic cannot be guaranteed over time. Climate change due to global warming may facilitate the spread of these diseases beyond the existing borders. Only recently have researchers and policymakers considered modern technology as a means for collecting critical information about vector-borne diseases, developing effective control strategies, and setting appropriate priorities. Eldridge reviews the basic concepts and judges their current validity.
Surveillance is critical to predict potential outbreaks of vector-borne diseases.
Information about the parameters limiting vectors are equally important. Treatments exist for some vector-borne diseases that can reduce the severity of the disease and alleviate painful symptoms. Richards concludes that GIS has also permitted the rapid assessment of drug coverage, analysis of impact indicators, and periodic retreatment for communities participating in the Guatemalan ivermectin distribution campaign. Treatment of infected animal reservoirs and human populations may also help to control the spread of the disease by reducing the abundance of the pathogenic agent within a region. He concludes that treating the animal population may, in fact, be more successful in reducing human infections than the sole treatment of humans.
