Once considered endemic only to tropical and subtropical climates such as Southeast Asia and northern Australia, melioidosis is expanding to non-endemic areas such as the southern US. Climate change is impacting infectious diseases, melioidosis being no exception. Now is the time to inform and prepare: as this Communicable episode’s title indicates, melioidosis is going global.
Join hosts Angela Huttner and Josh Davis on their in-depth exploration of melioidosis with invited experts Dr. Ella Meumann and Prof. Bart Currie from Royal Darwin Hospital, Darwin, Australia. Topics range from melioidosis discovery, clinical presentation, diagnostic approaches and host risk factors to the disease’s expanding endemicity.
Melioidosis is an infectious disease caused by the sapronotic agent Burkholderia pseudomallei and contracted by both people and animals through direct contact with contaminated soil, air or waters. Current burden estimates of 169’000 cases and 89’000 deaths per year are thought to be grossly underreported due to limited access to laboratory diagnostics and lack of clinical awareness. Experts call for melioidosis to be recognized as a neglected tropical disease in order to give this disease the urgent attention and resources it deserves.
