![]() Malaria on Great Exuma Island in the BahamasReleased: June 17, 2006 The Public Health Agency of Canada (PHAC) is closely monitoring an outbreak of P. falciparum malaria on the island of Great Exuma in the Bahamas and reports of malaria in tourists who have visited Great Exuma. The Agency has been notified of one lab-confirmed case of P. falciparum malaria in a Canadian traveller. In addition, the United States has also reported one case in a returning traveller. Both of these cases traveled to Great Exuma. As of June 14, 2006, 16 confirmed cases of malaria have been detected during the past week. All 16 cases occurred in Bahamian residents. None of the patients reported recent travel to places where malaria is endemic. Malaria is not endemic to the Bahamas. In 2005, only one case was reported and no cases had been reported during the 5 previous years. The Ministry of Health along with other Ministries are conducting active case detection and treatment; vector control including insecticide spraying, larviciding, and source reduction; and health education of the local population. Technical assistance is being provided by the Caribbean Epidemiology Center (CAREC) and the Pan American Health Organization (PAHO). Source: Pan American Health Organization, Ministry of Health of the Bahamas Malaria is an acute flu-like illness caused by one of four species of parasite of the genus Plasmodium; Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale and Plasmodium malariae. Infection with P. falciparum malaria can be fatal. The disease is most commonly transmitted to humans through the bite of an infected mosquito, specifically the female Anopheles mosquito, a dusk-to-dawn biter. Malaria is endemic (i.e., constantly present) in most of sub-Saharan Africa; in large areas of the Middle East, South Asia, South East Asia, Oceania, Haiti, Central and South America; and in parts of Mexico, North Africa and the Dominican Republic. For comprehensive information, please refer to the Public Health Agency of Canada's Disease Information Backgrounder on malaria.
The Public Health Agency of Canada recommends the use of antimalarial medication and personal insect protective measures (e.g., repellants) against mosquito bites for travel to Great Exuma, in the Bahamas. How to prevent malaria infectionTwo important measures can help you prevent malaria infection: avoiding mosquito bites and using effective antimalarial medications. Personal Measures to Avoid Mosquitoes Female Anopheles mosquitoes bite mainly during the evening and night. Using personal insect protective measures will reduce your risk of being bitten by these mosquitoes.
Antimalarial Medication (Prophylaxis) Antimalarial medications decrease the risk of developing symptomatic malaria. However, they do not provide 100% protection against the disease. Your individual need for antimalarial medications should be discussed with your physician or travel medicine professional several weeks before travel. If your physician or travel medicine clinic prescribes an antimalarial medication, it is important that you take it as directed in order to maximize the protective effect. Each drug has its own dosing regime that should be strictly followed. Because of the incubation period of the disease, these medications must be taken both before, during, and after travel. Travellers are reminded to complete their prescribed regimen of prophylaxis on their return. Atovaquone/proguanil must be taken for one week after returning from a malaria-endemic area. Chloroquine, doxycyline and mefloquine must be taken for four weeks after returning from a malaria-endemic area. For travellers who opt not to take malaria prophylaxis during their travel, PHAC does not recommend that they start chemoprophylaxis on their return home to Canada but advises that individuals seek immediate medical attention should they develop a fever and inform their physician that they have visited an area where malaria occurs so that they can be tested without delay. Important to Note: As a reminder... The Public Health Agency of Canada routinely recommends that Canadian international travellers consult their personal physician or a travel clinic four to six weeks prior to international travel, regardless of destination, for an individual risk assessment to determine their individual health risks and their need for vaccination, preventative medication, and personal protective measures. The Public Health Agency of Canada recommends, as well, that travellers who become sick or feel unwell on their return to Canada should seek a medical assessment with their personal physician. Travellers should inform their physician, without being asked, that they have been travelling or living outside of Canada, and where they have been. For additional information on malaria:
