[Monitoring situation of eliminating malaria in Shaoguan City from 2001 to 2014].

ABSTRACT

OBJECTIVE: To analyze the malaria monitoring situation in Shaoguan City from 2001 to 2014, and evaluate the efficacy of the malaria control and prevention work, so as to provide the evidence for formulating the effective eliminating malaria measures. METHODS: The microscopic examination monitoring points of "four-fever" patients were established in medical institutions at all levels in Shaoguan City from 2001 to 2014, and the fever patients were examined by microscopy and the active case monitoring was performed. By using the epidemiology method, the malaria incidence and classification of cases were described and analyzed statistically. RESULTS: From 2001 to 2014, 91 381 "four-fever" patients were monitored and 22 malaria patients were found with the average positive rate of 0.02%. Among the 22 malaria patients, 20 were imported (90.91%) and 2 were local cases (9.09%). The local patients were infected with Plasmodium vivax, and among the imported patients, 16 patients were infected with P. vivax, 2 infected with P. falciparum and 2 infected with P. ovale. No local infection cases were found since 2006. All the patients were timely treated and no second generation cases were found. From 2011 to 2014, 2 611 person-times were actively investigated in 7 counties (city) and no malaria patients were found. CONCLUSIONS: In Shaoguan City, there are remarkable achievements in the malaria prevention and control work. However, there are still imported cases in recent years, and therefore, the monitoring system should be perfected and the effective monitoring should be strengthened.
