ABSTRACT
Objective To analyze the epidemiological characteristics of malaria reported in the malaria surveillance system in Jinan City from 2012 to 2016,so as to provide the evidence for improving the ability of diagnosis,treatment,prevention and control of malaria.Methods The data of all reported malaria cases in the malaria surveillance system were retrospectively ana-lyzed.Results From 2012 to 2016,91 malaria cases were found in Jinan City,of which one patient died.All the cases were imported and 95.60%(87 cases)of them came from Africa(note:most of the people were Chinese residents who had been in Af-rica for the export of labor service and came back China).Falciparum malaria accounted for the most(82.42%,75 cases).All the cases were adult males,and were mainly migrant workers.The median time from onset to being confirmedly diagnosed was 5 days,and the median time from seeing a doctor to being diagnosed was 1 day.The medical institutions where the patients first visited were mainly municipal medical institutions(42 cases,46.15%).The misdiagnosis rate was 100% in village clinics and township health centers(8/8 and 2/2,respectively). The misdiagnosis rate was lowest in the municipal medical institutions (3/42,7.14%).There were 41 malaria patients(45.05%)with complications.Conclusions The situation of overseas imported malaria in Jinan City is becoming more and more serious.It is necessary to further strengthen the related professional training for doctors and strengthen the multi-sectoral cooperation for health education,etc.in order to find the cases in time and conduct the active standardized treatment,so as to prevent the second generation cases.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the epidemic characteristics of bacterial dysentery in Jinan municipality, and to provide scientific basis for effective strategy for bacterial dysentery control.</p><p><b>METHODS</b>The epidemiological characteristics of bacillary dysentery in Jinan from 1951 to 2005 were analyzed. A total of 485,333 cases in the span of 50 years were recorded, while the population-based case distribution was less than the total cases due to the data incompleteness during the Cultural Revolution.</p><p><b>RESULTS</b>The incidence of bacillary dysentery in Jinan has been decreasing by years with average incidence rate of 283.10/100,000. The significant differences were observed among the incidence rates of various ages(chi2 = 14.99, P < 0.05). There were four epidemic peaks, and all the incidence rates were about 1000/100,000. Age of onset mainly concentrated in the 0-4 years old, 20-years old and 30-years old. In terms of occupational distribution, workers accounted for 30.31%, the living-scattered children accounted for 22.71%, and the farmers accounted for 17.90%. The incidence focus was from July to September, which accounted for 71.57%. The peak of incidence emerged in August. The highest incidence in urban was 550.94/100,000.</p><p><b>CONCLUSION</b>Through the efforts of several generations of health workers, the incidence of bacillary dysentery in Jinan has been basically brought under control. Further step should be taken for the control of bacterial dysentery in urban areas and the management of bacterial dysentery in rural areas. Moreover, the biological characteristics of F2a should be a focus for the future study.</p>
