Today ARDS is more frequently recognized and managed in tropical countries, although published data from most locations is meager. The spectrum of disorders causing ARDS in tropical countries includes virtually all conditions encountered in the West. Additionally, tropical infections and other disorders are seen far more commonly. In particular, malaria and TB are important infections that predispose patients to ARDS in the tropics. Both of these illnesses give lead to severe forms of disease, such as falciparum malaria, acute miliary TB or TB bronchopneumonia, and may cause ARDS. Awareness of the complications helps in early recognition and differential diagnosis from several similar manifestations. Although earlier reports painted a gloomy picture of the outcome of these patients in general--mainly due to financial and logistic constraints--the scenario is improving quickly with better and wider availability of newer diagnostic and management tools.
