Regional Program of Action and Demostration of Sustainable Alternatives to DDT for Malaria Vector Control
in Mexico and Central America
DDT was extensively used for malaria vector control in Mexico and Central America during the 60s and 70s,
but the sprayings were gradually discontinued during the 80s and 90s. The remaining stockpiles of DDT still
present in the countries represent a permanent threat for the human health and the environment due to its
persistence in the environment.
Successful experiences of integrated malaria vector control without the use of DDT have been developed in
Mexico and several countries of Central America. The effectiveness of alternative strategies that promote
community participation and collaboration between governmental institutions, NGOs, and civil groups that work
at local level has been demonstrated specially in Mexico.
In the light of this situation the Pan American Health Organization - PAHO, together with the Commission for
Environmental Cooperation of North America - CEC and the ministries of health of Belize, Costa Rica, El Salvador,
Guatemala, Honduras, Mexico, Nicaragua, and Panama designed this project in two phases: the first one, called
PDF-B Phase, was developed between 2000-2002 with the objective of gathering actual information on the use of
DDT as well as the malaria control strategies present in the sub-region, as well as preparing a project proposal
to be submitted to the GEF; the second phase started in September 2003 with the agreement signed between UNEP
and PAHO implementing the GEF funded project during the period of 3 years.
