Australia, the world's highest incidence of MPM, 20 million people over the age is 3.54/10. Around the incidence of MPM is very large, ~ 0.6/10 0.1/10 million million, the overall upward trend. Among them, the most high Dayao County of Yunnan Province, the incidence rate of 8.5/10 million per year (1977 to 1983), 17.75/10 million (1987 ~ 1995). Male to female ratio, of 2:1 ~ 3:1, 6:1 in Australia.
Incidence of asbestos exposure to MPM the first time, usually 20 to 65 years. In the nineties of last century, European and American developed countries banned the production and use of asbestos, the incidence of MPM is expected to peak around 2020. China's industrial development and labor protection lagging behind, still the use of asbestos, the incidence of MPM will continue to grow in a very long time.
