„Emerging Infectious Diseases“: Dengue-Fieber, West-Nil-Fieber, SARS, Vogelgrippe, HIV

Some emerging infectious diseases have recently become endemic in Germany. Others remain confined to specific regions in the world. Physicians notice them only when travelers after infection in endemic areas present themselves with symptoms. Several of these emerging infections will be explained. HIV is an example for an imported pathogen which has become endemic in Germany. SARS and avian influenza are zoonoses with the potential to spread from person to person. Avian influenza in humans provides a possibility for the reassortment of a potential new pandemic strain. Outbreaks of dengue fever in endemic areas are reflected in increased infections in travelers returning from these areas. Currently, West-Nile-virus infections are only imported into Germany. The timely implementation of diagnostic, therapeutic and infection control measures requires physicians to include these diseases in their differential diagnosis. To achieve this goal, good cooperation between physicians, laboratories and the public health service is essential.
