Cholera in Fribourg. Apropos a case

: A 41-year-old man from Cameroon was admitted to the Hospital of Fribourg (Switzerland) for watery diarrhea 3 months after cholera vaccination. Stool cultures were positive for Vibrio cholerae, biotype El Tor. Treatment consisted of rehydration (up to 9 litres per day) and correction of metabolic acidosis. No antibiotics were administered. The diagnosis of cholera should be considered in the presence of watery diarrhea in travellers or immigrants from countries suffering from the pandemic, even though, before this case, there had been no registered case for four years in Switzerland and none for twenty years in Fribourg.
