According to the case reporting system, the number of malaria cases in China numbered 34,645 (Taiwan Province and Hong Kong not included) in 1997, with a mean incidence of 2.91 per a hundred thousand and lethal cases of 46. However, the estimated number of actual malaria cases based on investigations at provincial level was 220,000-250,000, showing a slight diminution as compared with that in 1996. Yunnan and Hainan were continued to be the major provinces endemic for malaria, where the number of malaria cases amounted to 46% of the total in the whole country. In Yunnan Province, an increase of outbreak spots and resurgence of malaria incidence in border region were reported, while the incidence was stable or slightly declined in most other provinces, but was fluctuated in provinces distributed with Anopheles anthropophagus. Blood examination on febrile patients for 9,209,102 man/time in 1,294 counties of 18 provinces/municipalities/autonomous regions (P/M/A) with a population of 569,703,000 detected 26,816 cases positive for malaria parasite, showing a mean positive rate of 0.29%; of which the number of falciparum malaria cases were 4,114 (including mixed infections with vivax malaria, the same below), accounting for 15.3% of the total parasite positives; of the three quartan malaria cases detected, one was infected via blood transfusion. Totally 568,783 target-population and migratory people were surveyed, 2,861 were positive for malaria parasite, with a mean parasite rate of 0.50%; and 586 falciparum malaria cases were among the positives. As a whole, the endemicity of falciparum malaria was still confined to 44 counties of Hainan and Yunnan Provinces. Imported falciparum cases were reported in 74 counties located in 17 P/M/A, however, no introduced falciparum malaria cases were recorded.
根据病例报告系统，1997年中国疟疾病例数为34645例（未包括台湾省和香港地区），平均发病率为十万分之2.91，死亡病例46例。然而，根据省级调查估算的实际疟疾病例数为22万至25万，与1996年相比略有下降。云南和海南仍然是疟疾的主要流行省份，疟疾病例数占全国总数的46%。云南省报告边境地区疟疾暴发点增加，发病率回升，而其他大多数省份发病率稳定或略有下降，但在嗜人按蚊分布的省份有波动。对18个省/直辖市/自治区（省/市/区）1294个县中56970.3万人口的9209102人次发热病人进行血检，检出疟原虫阳性病例26816例，平均阳性率为0.29%；其中恶性疟病例4114例（包括间日疟混合感染，下同），占疟原虫阳性总数的15.3%；检出的3例三日疟病例中，1例为输血感染。共调查568783名目标人群和流动人口，疟原虫阳性2861人，平均带虫率为0.50%；其中恶性疟病例586例。总体而言，恶性疟的流行仍局限于海南和云南的44个县。17个省/市/区的74个县报告有输入性恶性疟病例，但未记录到输入性恶性疟的本地传播病例。
