Abstract/OtherAbstract:
A 63-year-old woman from Colonial Beach, Westmoreland County, VA, was diagnosed with Plasmodium falciparum malaria on July 19, 1998. The woman had no history of international travel, intravenous drug use, blood transfusion, or other risk factor for contracting the disease. She seldom left the county and generally spent her evenings indoors, leading to the conclusion that she had been bitten locally by an infected mosquito. Colonial Beach is host to a population of migrant agricultural laborers from areas in which malaria occurs, but a blood survey of 89 Haitians and Mexicans failed to find Plasmodium parasites, specific antibodies, or clinical cases of malaria. Mosquito surveys were conducted during 2 days (July 22 and 28, 1998) with carbon-dioxide-baited light traps, larval and pupal collections, and landing collections. Thirteen species of mosquitoes were identified morphologically, including 4 potential vectors: Anopheles crucians, An. punctipennis, An. smaragdinus (new state record), and An. quadrimaculatus s.s. (new state record). Identifications of the latter 2 species were confirmed by sequencing of the ITS2 DNA region from adults reared from locally collected larvae. Anopheles smaragdinus was the most common biting species among the potential vectors, although An. crucians was the most abundant in other kinds of collections. In addition, Ae. albopictus was collected in Westmoreland County for the 1st time.
