Epidemiology Non-cholera Vibrio Infections


The purpose of this study is to identify the epidemiological and clinical characteristics of patients diagnosed with non-cholera Vibrio infection in Western France from 2000 to 2019.

  • Study Type: Observational

Detailed Description

Vibrios are gram-negative, ubiquitous bacteria of the marine flora and are found particularly in warm waters. For example, the incidence is high in Florida and Vibrio infections are now reportable in the United States. Different species of Vibrio are described. A distinction is made between choleric vibrios belonging to serogroups O1 and O139, responsible for cholera epidemics, and non-choleric vibrios. Our study will focus on non-cholera vibrios. Vibrio infections can occur by eating contaminated raw seafood or by exposure of a wound to the marine environment. They occur mainly during the hot summer months. This can be explained on the one hand by higher water temperature and on the other hand by increased beach use. With global warming, it is possible that Vibrio infections may increase in number and location.
