Global status of DDT.
The World Health Organization has recommended
dichlorodiphenyltrichloroethane (DDT) for indoor residual spraying to
control malaria when suitable alternatives are not available, and DDT is
currently used for this purpose in approximately 14 countries, van den
Berg (p. 1656) reviews the use of DDT and current evidence concerning
its benefits and risks in relation to available alternatives. He argues
that a comprehensive cost assessment of DDT versus its alternatives is
needed that takes unintended effects on human health, the environment,
and international trade into account. He also argues that integrated
vector management can provide a viable framework for developing and
implementing effective and sustainable alternatives to DDT.
