Most of the cases were males (only 2 females), the average age was 38.8 years, and the occupation was mainly labor service worker abroad (94 cases, 97%). The infection source of these cases mainly came from Africa. From 2011 to 2015, 151 980 fever patients received malaria blood tests, and the positive rate was 0.07%.
