## Abstract

Background: On December 14, 2024, the tropical cyclone Chido hit the French department of Mayotte, an archipelago in the western Indian Ocean. It was the most violent storm in at least 90 years, causing widespread devastation.

Objectives: We address different aspects of the Chido disaster, including deaths, Mayotte’s vulnerabilities, and risk management, and review the hurricane’s health consequences, notably post-traumatic stress disorder (PTSD).

Methods: Information was collected through informal interviews with inhabitants, physicians, and stakeholders. Public data were provided by the public health authorities and through online searches.

Findings: Addressing pre-Chido vulnerabilities, risk perception, fatality assessment, community management, and post-Chido psychological consequence constitutes a major challenge for the Mayotte society.

Conclusion: We recommend launching an exploratory health study and planning to provide medico-psychological support to victims and to favor scientific investigations.
