ABSTRACT
Using the theory and method of health economics,we analyzed CER and ICER in early elimination stage (2005-2009),the late elimination stage (2015-2010) and the post elimination phase (2016-).Results showed that annual total cost of investment was as following:64 235 144.8 Yuan in early elimination stage,11 250 248 Yuan in the late elimination stage,and 11 075 228.8 Yuan the post elimination phase.Effect analysis showed that the difference of the three-stage monitoring measures was statistically significant (P＜0.01).Number of cases within 3 days of onset (rate) prompt monitoring measures had the best effect in the late elimination stage,number of blood tests (rates),number of cases reported (rates) and number of cases within 1 days of onset (rate).Prompt monitoring measures had the best effect in the post elimination phase.CER and IC-ER showed that taking the number of blood test as the effect index,the monitoring measures in the late elimination stage were more cost effective.The number of cases reported,number of cases within 3 days of onset and number of cases within 1 day of onset were as the effect index,the monitoring measures in the post elimination phase were more cost effective.The elimination effect for monitoring measures after stage was optimal,cost the least,and might be the most effective.The study provides basic data for Fujian Province to strengthen the monitoring of imported cases of malaria on the construction of the management mechanism,and scientific and effective evaluation of monitoring measures,which has very important practical value and significance.
ABSTRACT
Objective To analyze the results of 3 investigations(2002-2004,2008-2009,and 2016)of major parasitic dis-eases in Shixing County,so as to provide the evidence for formulating further control strategies. Methods With the stratified clus-ter sampling method,5 administrative villages were investigated. A total of 200 residents aged above 3 years were sampled in each village to investigate the eggs of soil-transmitted nematodes with Kato-Katz technique,and the swab method was applied for detecting the eggs of Enterobius vermicularis in children aged 3-9 years. χ2 test was used for statistical analysis. Results To-tally 3857 individuals were surveyed for intestinal parasites,and 5 species of parasites were found and the total infection rates were 28.37%,4.32%and 0.50%in the 3 investigations respectively,and there were statistically significant differences between any two investigations(χ2=287.64,327.60 and 31.89 respectively,and all P<0.01). The infection rates of Ascaris lumbricoi-des,hookworm,Trichuris trichiura and Clonorchis sinensis significantly decreased in the third investigation compared with those in the first investigation(χ2 =424.55,55.45,43.40 and 26.12 respectively,all P<0.01). However,there was no significant difference between the E. vermicularis infection rates of the first investigation and the third investigation(χ2=0.16,P>0.05). Conclusions Compared with the status in the first investigation,the infection rates of A. lumbricoides,hookworm,T. trichiura and C. sinensis are significantly decreased by 90%or more in the third investigation. However,the children's infection rate of E. vermicularis is still very high. Therefore,we should focus on the comprehensive control measures of E. vermicularis infection while formulating further control strategies of parasitic diseases.
