Abstract

Entomologic monitoring of filarial infections, xenomonitoring, may have advantages in certain epidemiologic situations to assess the presence of infections in humans. Hemalum staining and dissection and polymerase chain reaction (PCR) were compared to determine the filarial infection status of () mosquitoes in American Samoa. The overall prevalences of and infections in were, respectively, 0.16% and 1.06% by dissection and 0.69% and 1.77% by PCR. Human filarial worm DNA rates in and were 1.16% and 0.38%, respectively. The results suggest that transmission to humans may be continuing at low levels in some villages despite recent completion of 5 years of mass drug administration. PCR testing of mosquitoes collected using the BG-Sentinel traps represents a promising alternative to landing catches for assessing the transmission of filariasis in areas where and related species are the primary vectors.
