Thailand is one of the top asbestos importing countries (the 5th importer of asbestos in the world). The diseases relevant to the asbestos are among the eight occupational diseases covered by an active health surveillance scheme run by the Bureau of Occupational and Environmental Diseases. However, most of the scheme’s work has been focused on silicosis and lead poisoning because of a larger target population; and very little information about asbestos-related diseases is available from the scheme.
