To diagnose an infectious disease, there are several methods of examination:

  • Anamnesis (ask the medical history): All complaints can be further limited by specific questions. For example, contact with sick family members may indicate a path of infection, and a trip abroad a few days may suggest exotic pathogens.
  • Inspection (viewing) and Fiebermessen: With purulent deposits on a wound you immediately think of bacteria and classic signs of inflammation Eye or ear direct the suspicion quickly to infection - as well as an elevated temperature
  • Examination of body fluids: Inflammatory cells, pathogens and their metabolites can be detected in the various body fluids - whether blood, cerebrospinal fluid or a stool sample, so pathogens can be identified. A wound is taken from open wounds and breath tests indicate that the stomach is infected with bacteria.
