Flea outbreak at United Nations base in South Sudan: A public health challenge

Background: A large number Indian troops are deployed in International Peacekeeping Missions Worldwide and are exposed to emerging and re-emerging vectors and diseases in unfamiliar terrain. This article describes the experience of a flea outbreak among Indian UN Peacekeepers in a remote part of South Sudan. Methods: Health visits to the area confirmed presence of dog fleas. Flea bites disrupted daily routine of the unit and many troopers reported to medical facilities with severe dermatitis. Death of a field rat in the immediate vicinity along with detection of rat fleas was cause for worry as Plague and other flea-borne diseases are known to occur in the country in sylvatic form. Result: Conventional vector control measures had limited impact and unconventional measures had to be devised due to limited capacity in the inaccessible area. Severity of the problem, potential to cause flea-borne diseases and unavailability of conventional insecticides prompted the author to use Aviation Turbine Fuel (ATF) for area spray in the UN base. Conclusion: Healthcare providers in fast-evolving operational situations such as Peacekeeping Missions need to maintain high index of suspicion and often adopt innovative methods to ensure effective public health cover to troops
