Background: Returning travelers with fever pose challenges for clinicians because of the multitude of diagnostic alternatives. Case data in a Finnish tertiary hospital were analyzed in order to define the causes of fever in returned travelers and to evaluate the current diagnostic approach.
Methods: A retrospective study of patient records comprised 462 febrile adults who, after traveling in malaria-endemic areas, were admitted to the Helsinki University Central Hospital (HUCH) emergency room from 2005 to 2009.
This randomized, controlled study among pregnant women evaluated the prevaccination distribution of anti-pneumococcal (Pnc) antibodies (Ab), the immunogenicity and reactogenicity of Pnc polysaccharide vaccine, and transplacental transfer of Ab. The Pnc vaccine group (N=106) received Pnc PS vaccine, Hemophilus influenzae type b conjugate vaccine and tetanus toxoid; the control group (N=54) received tetanus toxoid only. Sera and cord blood were assayed for anti-pnc Ab using enzyme immunoassay.
