[The new guideline for gastrointestinal infections].

Gastrointestinal infections are still responsible for around 60% of the infectious diseases that must be reported in Germany and are probably among the most common gastroenterological diseases. The main therapy for gastrointestinal infections remains oral fluid replacement. The recommendations for Clostridioides difficile infections (CDI) have been adapted according to the current data and based on international guidelines; vancomycin or, especially if there is an increased risk of recurrence, fidaxomicin should now be used primarily in CDI. In the case of febrile diarrhea and/or bloody diarrhea, malaria diagnosis should be carried out immediately.
