Abstract:
Background:Ciguatera fish poisoning (CFP) is a disease caused by the ingestion of poisonous coral reef fish. To the
best of the author’s knowledge, no attempt has so far been made to consolidate available reports of outbreaks in order to characterize the toxidrome of CFP in the Philippines.
Objective:To review and consolidate data from epidemiologically-documented CFP outbreaks in order to characterize
the toxidrome of CFP in the Philippines and identify the areas of high risk for outbreaks.
Methods:Epidemiologic reports of CFP outbreaks in the Philippines were reviewed. A compilation of symptoms of CFP patients was done to describe the toxidrome. High risk areas in the Philippines were identified.
Results:Ten reports were retrieved related to 17 CFP outbreaks from 1988 to 2010. No epidemiologic reports were found after 2010. Consolidation of reported symptoms showed a CFP toxidrome with prominent paresthesia, muscle weakness, and myalgia with some gastrointestinal symptoms. Based on the reports, the high risk islands identified were Palawan, Panay, Romblon, the islands in the Cuyo Pass, and Basilan. Cases of CFP continue to be encountered but are not reported to public health epidemiologists.
Conclusion:When put together, the reports describe a CFP toxidrome where the neurologic symptoms predominate over
the gastrointestinal symptoms. Most of the cases occurred in the west central and southern portion of the archipelago suggesting a higher risk for CFP in that area. Cases of what appear to be CFP continue to be diagnosed although they are not reported to government epidemiology units. More systematic surveillance of CFP by government agencies is needed.
