In May 2000, CDC was asked to assemble a team to investigate reports of a widespread outbreak of Q fever (Coxiella burnetii infection) in Bosnia-Herzegovina. Brucellosis was also suspected in the outbreak. In a short period of time, we were able to gather supplies, establish collaboration, and rapidly deploy a field laboratory for the serodiagnostic testing of animal and human specimens. Strategy, problems, and insights on organization, transport, and deployment will be discussed.
