Bed bugs collected from huts in an HBV endemic area in northern Transvaal, South Africa, were hepatitis B surface antigen positive,43 as were samples collected from Senegal,42 Egypt,45 the Ivory Coast,54 and China.44 Hepatitis B surface antigen has also been shown to persist in bed bugs for more than 7 weeks after experimental feeding, but no replication of HBV was detected in the insects.34,36 Polymerase chain reaction assays have detected HBV DNA in bed bugs and their excrement up to 6 weeks after feeding on infected blood.38,39 Despite these findings, a 2-year bed bug eradication project in Gambia had no effect on rates of HBV infection, despite 100% reduction of bed bug numbers.55, To our knowledge, no study to date has demonstrated bed bug “vector competence” (the ability to acquire, maintain, and transmit an infectious agent), and an attempt to demonstrate vector competence for HBV failed in an experiment with chimpanzees.40 In that experiment, bed bugs were fed HBV-infected blood through an apparatus containing artificial skin-like membranes.
