A recent modelling study estimated that there are 2800 deaths due to melioidosis in Thailand yearly. The Melioidosis Network (formed 2012) has been working closely with the Ministry of Public Health (MoPH) investigate and reduce burden this disease. Based on updated data, incidence is still high Northeast Thailand. More than 2000 culture-confirmed cases diagnosed general hospitals microbiology laboratories region each year. mortality rate around 35%. endemic throughout Thailand, but it not...
