[Preventive strategy of economy class syndrome].

Economy class syndrome (ECS) refers to a series of symptoms, such as lower limb swelling, chest pain, dyspnea, and sudden death, that occur during or after a long-distance flight. Its essence is venous thromboembolism. ECS, as a preventable syndrome, is one of the causes of sudden death in long-distance travelers. Medical assistance to the African region is a very important diplomatic matter of China. It often takes medical workers more than 10 hours of long-distance flight to reach the recipient country. Therefore, it is essential to improve the understanding of ECS and corresponding prevention strategies among the long-distance traveling people including medical workers assisting Africa, which could guarantee their health and ensure the smooth implementation of the work of assisting Africa.
