While Southeast Asia and northern Australia are well recognized as the major endemic regions for melioidosis, recent reports have expanded the endemic zone. Severe weather events and environmental disasters such as the 2004 Asian tsunami have unmasked locations of sporadic cases and have reconfirmed endemicity in Indonesia. The endemic region now includes the majority of the Indian subcontinent, southern China, Hong Kong and Taiwan. Sporadic cases have occurred in Brazil and elsewhere in the Americas and in island communities such as New Caledonia, in the Pacific Ocean, and Mauritius in the Indian Ocean. Some of the factors that are critical to further elucidating the global distribution of Burkholderia pseudomallei and melioidosis include improved access to diagnostic laboratory facilities and formal confirmation of the identity of bacterial isolates from suspected cases.
