These vulnerabilities are set to increase under the impact of climate change, particularly global warming, conditions which generally favour microbial growth and proliferation.Factors favouring urban epidemic risks are: (1) Deterioration in water and food hygiene. (2) Urban air pollution. (3) Movement towards urban areas of mosquito vectors establishing vectorial systems allowing the introduction or return of pathologies linked to this entomological risk, such as deng
