Reducing dengue vector breeding

TDR news item

Results from a multi-country study in Latin America on using a combined environmental and community approach to reducing dengue vector breeding has been published in BMC Infectious Diseases. The study identified the types of containers that breed the most Aedes aegypti mosquitoes that transmit the dengue virus, and best ways to reduce the breeding.

Dengue is an increasingly important public health problem in most Latin American countries and more cost-effective ways of reducing dengue vector densities to prevent transmission are in demand by vector control programs.

The study was conducted simultaneously in 5 countries: Mexico (Acapulco), Colombia (Girardot), Ecuador (Machala), Brazil (Fortaleza) and Uruguay (Salto) from November 2010 to August 2011.

The paper is one of several coming out of the TDR eco-bio-social research that began in 2009 in collaboration with the WHO Regional Office for the Americas (PAHO) and funded by the Ecosystem and Human Health Program of the International Development Research Centre (IDRC) of Canada.
