Results from the microtest (mark III) drug sensitivity tests (1993–2002). Colour scheme matches that of Map 1. These data have been collected by the Bureau of Vector Borne Diseases, Ministry of Public Health, Thailand and have not previously been reported. For each year and province, at least 30 clinical isolates were used to calculate the average IC50. The detailed results of each assay have since been discarded, meaning that error bars and variance between assays cannot be calculated for this component of the data.
