A general survey has been made of tuberculosis in the Jesselton – Tauran area. Climatical, living, and occupational conditions tend to favour the spread and advancement of the disease. The death rate is high, but has been influenced by conditions attributable to the war. The native population, due to their mode of life, succumbs more easily to the disease that do the Chinese. Cases are usually seen in the late stages, mainly due to ignorance.
