Worldwide, malaria is one of the most devastating of the communicable diseases,
causing at least 1,000,000 deaths annually, not to mention an enormous
burden of disability and medical costs. While transmission has not been documented
in Oregon for decades, malaria remains the most commonly reported
vector-borne disease in our state — all cases resulting from exposures outside
the United States. Competent anopheline mosquitoes are resident in Oregon, so
limited local transmission remains a theoretical possibility. Rates in Oregon are
similar to the national average. Surveillance data are contributed to the national
database, which is used to tailor recommendations for prophylaxis and
treatment.
