Abstract

Abstract:

The reported data concerning malaria during 2010-2017 in Yantai City were collected and analyzed with regard to prevalence, sources of infection, species of Plasmodium and distribution of the disease. A total of 129 malaria cases were reported in Yantai City during 2010-2017, consisting of 103 cases(79.8%) of falciparum malaria, 12 (9.3%) vivax malaria, and 14 (10.9%) ovale malaria. All of them were imported from other countries, with a majority from Africa (93.8%, 121/129) and a minority from other Asian nations (6.2%, 8/129). Blood test was conducted in the City for 116 034 febrile patients, with a positive detection rate of 0.1%. The disease onset showed no significant seasonal and regional variations. The reported cases comprised 127 male cases, concentrated in the 39-49 age group. They were mainly workers, peasants, and unemployed persons. The median interval from symptom onset to diagnosis was 3 days, and 15 (11.6%) patients received definite diagnosis within 24 h. After medication, among the 129 malaria cases, 1 patient died and others recovered after regular treatment. The cases were mainly reported by clinical medical institutions (90.7%, 117/129), while 5.4% (7/129) were reported by disease control institutions.
