Climate suitability for infectious disease transmission - Vibrio


Vibrio bacteria are found in lowly saline, warm waters and can cause a range of human infections, including gastroenteritis, wound infections or blood poisoning (septicaemia). This indicator assesses the influence of a changing climate on the environmental suitability for the transmission of these infectious diseases.


The indicator is based on infection rates derived from USA data, but its calculation would benefit from a more accurate infection rate specific for the European context and adjusted for surveillance limitations and underreporting in different countries.

Sea surface salinity data in coastal regions are prone to biases in salinity variability due to heavy rainfall, river runoff or ice melting events.

The indicator is based on suitable climate conditions only, disregarding other potentially important drivers (e.g., population growth), environmental predictors of pathogenic Vibrio infections (e.g., cholorphyll-a, turbidity) or observed disease case data.

Reference information

  • Estimates for SST were obtained from NOAA Optimum Interpolation 1/4 Degree Daily Sea Surface Temperature (OISST) Analysis version 2 for the period 1982-2019. This dataset is provided by the NOAA/OAR/ESRL PSD.57

  • The salinity fields were created from daily data obtained from Mercator Ocean Reanalysis
