Bed bugs and public health: new approaches for an old scourge.

Objective: To share four Canadian cities' experiences with bed bug infestations and to explore public health roles in managing them.

Methods: We summarize presentations from a workshop at the 2010 Canadian Public Health Association Conference which examined the re-emergence of bed bugs in Canada and compared management approaches of municipal and public health authorities in four large Canadian cities. We include updates on their activities since the workshop.
