Objective To characterize the prevalence and epidemic situation of imported malaria cases in Songjiang District of Shanghai from 2013 to 2022， and to provide evidence for malaria prevention and control.

Methods Related data were collected and analyzed， including malaria cases， blood testing of febrile patients， and mosquito surveillance in Songjiang from 2013 to 2022.

Results A total of 13 002 febrile patients in Songjiang were tested for plasmodium parasites from 2013 to 2022， among which 18 malaria cases were confirmed， including 17 cases of falciparum malaria and 1 case of ovale malaria. Moreover， a total of 36 malaria cases were notified in Songjiang through the National Notifiable Disease Reporting System from 2013 to 2022， including cases reported from Songjiang District and other districts or provinces with physical addresses in Songjiang. Of them， there were 31 cases of falciparum malaria， 2 cases of vivax malaria， 2 cases of ovale malaria and 1 case of quartan malaria. The gender ratio of male to female cases was 17∶1， and the majority was young and middle aged. In addition， 35 cases were imported from Africa and 1 case from southeast Asia； 34 cases were migrant workers， and 2 cases were travellers abroad； 17 cases were found and reported in Songjiang， 15 cases were reported from other districts of Shanghai， and 4 cases were reported from other provinces； 27 cases were treated in Shanghai， 3 cases were treated in other provinces and 6 cases were treated with self-provided antimalarial drugs. Mosquito surveillance in Songjiang showed that density of Anopheles sinensis was extremely low.

Conclusion No indigenous malaria case has been notified in Songjiang since 2008. Malaria surveillance on migrant workers remains the focus of malaria prevention and control. Furthermore， achievement of malaria elimination in Songjiang should be continually enhanced to avoid potential further transmission of imported malaria.
