¡¡¡¡Abstract£º¡¡Lassa fever,listed as one of priority research and development zoonotic diseases by WHO,is caused by Lassa fever virus,and mainly transmitted by rodents and can cause high morbidity and mortality.The disease was first reported in Nigeria in the 1950 s,and it is mainly epidemic in West Africa.So far,imported cases of Lassa fever have been also reported in countries in Europe,America,and Asia.In recent years,the continuous outbreaks of Lassa fever in Nigeria had once again attracted the attention of the world.With the advancement of “The Belt and Road”initiative,frequent international exchanges,and the increase in our country's assistance to Africa and the military's peacekeeping missions in Africa,the risk of infection in endemic areas and import into China of Lassa fever increased year by year.The paper mainly introduces the etiology and clinical characteristics,epidemiological characteristics,epidemic distribution and prevention and control of Lassa fever,analyzes the potential threats of Lassa fever to China,and proposes prevention and control measures for Lassa fever.
