A brief review on the respiratory aerosols transportation in ventilated built environment using CFD method was carried. Performs in-depth literature study about room model, manikin, respiratory aerosols, ventilation type and aerosol particulate matter model. Based on this study, summarizes the research status in quo and the main problem existed at home and abroad. The results showed that (1) recent studies mainly concerned on specific environment such as treatment room, aircraft cabin mock-up, office room, bus and high-speed rail cabin and based on the specific environment to simulate, (2) some studies put emphases only on droplet or droplet nuclei, and at the same time, evaporation, deposition and coagulation were neglected sometimes, (3) there were lack of studies on moving manikins (4) there was no finial conclusion about which ventilation pattern was better for reducing the risk of cross-infection from airborne transmission diseases in a certain place, (5) to choose the Lagrangian method or the Eulerian method for a certain problem generally depends on the subjects, targets, and the computer resources available.
