The incidence of imported malaria decreased since 2016 with 36 cases in 2016, 22 cases in 2017 and 20 cases in 2018. Almost all the cases (99.1%, 321/324) were imported from abroad, with only 3 cases (0.9%) were domestically imported from other provinces in China. For those imported cases, 96.9% of them were imported from Africa, of which 39.2% from Equatorial Guinea (123 cases) and 17.2% from Angola (54 cases). All cases were male, 45.1% of them were within the age of 40-49 years old (146 cases). Most of them (91.0%, 295/324) were the migrant workers returned from abroad. There was no seasonal difference of imported malaria cases. Total 75.6% (245/324) of them were infected with Plasmodium falciparum, 4.3% (14 cases) with P. vivax, 14.5% (47 cases) with P. oval, 4.6% with P.malariae (15 cases) and 0.9% (3 cases) were the mixed-infection. Donghai county contained the most cases (46.9%, 152/324), followed by Ganyu District (33.0%, 107/324). Half of the malaria cases seeked for the first medication at local CDC (156 cases) and half at the local medical institutions (156 cases), but most of the malaria cases received confirmed diagnosis at local CDC (62.0%, 201/324).
