Abstract
Global efforts to eliminate lymphatic filariasis are based on the annual mass administration of antifilarial drugs to reduce the microfilaria reservoir available to the mosquito vector. Insecticide-treated bed nets are being widely used in areas in which filariasis and malaria are coendemic.
We studied five villages in which five annual mass administrations of antifilarial drugs, which were completed in 1998, reduced the transmission of
Village-specific rates of bites from anopheline mosquitoes ranged from 6.4 to 61.3 bites per person per day before the bed-net distribution and from 1.1 to 9.4 bites for 11 months after distribution (P<0.001). During the same period, the rate of detection of
Vector control with insecticide-treated bed nets is a valuable tool for

<p id="P4">We studied five villages in which five annual mass administrations of antifilarial drugs, which were completed in 1998, reduced the transmission of <italic>Wuchereria bancrofti</italic>
, one of the nematodes that cause lymphatic filariasis. A total of 21,899 anopheles mosquitoes were collected for 26 months before and 11 to 36 months after bed nets treated with long-lasting insecticide were distributed in 2009. We evaluated the status of filarial infection and the presence of <italic>W. bancrofti</italic>
DNA in anopheline mosquitoes before and after the introduction of insecticide-treated bed nets. We then used a model of population dynamics to estimate the probabilities of transmission cessation.</p>
</sec>
<sec id="S3"><title>RESULTS</title>
<p id="P5">Village-specific rates of bites from anopheline mosquitoes ranged from 6.4 to 61.3 bites per person per day before the bed-net distribution and from 1.1 to 9.4 bites for 11 months after distribution (P<0.001). During the same period, the rate of detection of <italic>W. bancrofti</italic>
in anopheline mosquitoes decreased from 1.8% to 0.4% (P = 0.005), and the rate of detection of filarial DNA decreased from 19.4% to 14.9% (P = 0.13). The annual transmission potential was 5 to 325 infective larvae inoculated per person per year before the bed-net distribution and 0 after the distribution. Among all five villages with a prevalence of microfilariae of 2 to 38%, the probability of transmission cessation increased from less than 1.0% before the bed-net distribution to a range of 4.9 to 95% in the 11 months after distribution.</p>
