3 Results
The 3.1 District of Qingpu from 2001 to 2010, the epidemiological characteristics of measles (1) from 2001 to 2010 in Qingpu, mainly in sporadic measles outbreaks, the average annual incidence rate of 8.97/10 million (0.10/10 million 35.49/10 million), can be divided into two stages: the fluctuation period (2001 - 2007) and decline period (2007 - 2010), the following changes the fluctuation of annual incidence (2.23/10 million 35.49/10 million), the annual decline in incidence decreased year by year (9.16/10 million 0.10/10 million).
(2) families, factories and migrant workers' children schools are the main places for the outbreak of measles. Among them, 2 cases are the main causes of family outbreaks. Factories and migrant workers' children schools are high-risk places for outbreaks of many cases.
(3) there are measles all year round in Qingpu District, mainly in spring and summer, and from 4 to June, the total number of cases is 55.77%..
(4) the age of onset is mainly concentrated in the 5 years old group and the young and middle-aged age group (20 ~ 25 ~ 30 ~ 35~40), accounting for 35.44% and 48.90% of the total number, respectively. 8 month old cases account for 16.21%. of the total number.
(5) the population and non domicile cases accounted for 53.16% and 46.84%.3.2, respectively, and the level of measles immunization before the newly enrolled students in the school of migrant workers' children were strengthened.
(1) the geometric mean concentration (GMC) of IgG antibody before immunization was 998.96mIU/ml (95%CI: (912.931093.10)), and the positive rate was 96.96%.
(2) of different types of schools (kindergarten, primary school, junior high school) there was no significant difference (F=1.19, P=0.30, GMC), no statistically significant difference between the positive rate of antibody (x2=0.36, P=0.83); different school history (had no schooling in history, household education, school education in Shanghai) no significant object the difference of GMC (F=1.22, P=0.30), there was no significant difference between the positive rate of antibody (x2=3.46, P=0.18).
(3) 38.29% subjects without vaccination certificate or has been lost, measles vaccination related more than 2 doses accounted for 37.95%, with an unknown history accounted for 48.18% different vaccination history (more than 2 agents, 1 agents, 0 agents, unknown) no significant difference (F=0.75, P=0.53, GMC). New student measles vaccination related agent in the new school students school categories, birth places, new students after school, family income, family, number of children, parents' age, parents' years of schooling has statistically significant difference in distribution of factors.
3.3 the knowledge of parents' knowledge of new students' parents in the school of migrant workers' children
(1) the relevant cognitive 606 cases of migrant workers' school new students according to the awareness rate from high to low is the measles vaccine to prevent disease, whether the new entrance vaccination certificate, vaccination is money, measles vaccination starting months and measles vaccination doses, including measles vaccination starting months and measles vaccination dose lowest awareness rate were 17.49% and 11.39%, the highest correct rate of measles vaccine for disease prevention, was 73.76%, the knowledge awareness rate was statistically significant difference (X2=685.90, P0.001).
(2) knowledge quiz with an average score of 2.72 points (95%CI: (2.66,2.78)), scoring less than 3 points in 418 cases (68.98%), father, mother, grandparents and other group average scores had no significant difference (F=2.894, P=0.0560.05). The parents of measles vaccination related knowledge score of the school in the new category. The admission of students born place, family income, family, number of children, parents' age, parents' years of schooling has statistically significant difference in distribution of factors.
(3) the migrant workers children school parents newly enrolled students think it necessary for the children of measles vaccination in 539 cases (88.94%), the group were inoculated to order from high to low for the mother group (90.54%) (88.89%) father group other groups (78.79%), the difference was not statistically significant (X2=4.04, P=0.130.05).
(4) measles vaccination approaches to obtain knowledge according to the proportion from big to small are: medical personnel, written materials, radio and television and other network, which, through the propaganda of medical worker informed through the network accounted for 40.10%, accounted for 1.16%, the difference was statistically significant (X2= 359.22, P0.001).
3.4 knowledge of related knowledge of immunization program staff
(1) 90.48% of the respondents believe that the incidence of measles is generally not dangerous under modern medical conditions. 73.02% of the respondents believe that measles is not an important infectious disease affecting the health of the crowd. 88.89% of the respondents believe that the incidence of measles in Qingpu is at the sporadic level.
(2) 23.81% of the investigators believed that the Qingpu district was able to achieve the goal of eliminating measles in 2012, and 38.10% and 33.33% of the investigators found it difficult to say and failed to achieve.
(3) 60.32% of respondents and 30.16% respectively that the vaccine did not reach effective vaccination rate and the floating population is the main factor of the current measles cases; 50.79% of the respondents think that the children against measles vaccination rate of 2 agent needs to be further improved, 39.68% of the subjects that have reached a higher level; 66.67% of respondents and 26.98% are that parents and parents do not pay attention to not get enough information is the effect of measles vaccination rate is the main factor; 74.60% of the respondents think that foreign children are the most affected measles vaccination coverage.
(4) 38.10% of the respondents think there is no need to carry out large-scale measles immunization activities, 53.97% of the respondents think it is necessary to regularly focus groups carried out the measles vaccine leak replant work, 85.71% of the respondents think that the solid foundation to carry out immunization, with respect to regularly carry out large-scale leak replant measles vaccine immunization more targeted.
(5) 74.60% and 25.40% of the respondents believe that medical staff were face-to-face publicity and brochures, leaflets, posters and other subjects for parents of children is the most effective propaganda way.46.03% and 36.51% respectively that effectively expand the relevant knowledge and provide a more convenient vaccination service is the most effective way to improve measles vaccination rate.
4 Conclusion
(1) the incidence of measles in Qingpu District in the low incidence rate, emission levels, family, factory, key places, schools for migrant workers' children for measles outbreaks of low age, young people focus on measles cases. (2) of migrant workers into the new school district of Qingpu school students strengthen before immunization of measles antibody and the level of antibody positive rates were at a high level. (3) the migrant workers children school new student survey of measles related vaccine vaccination rate is not high, the freshman school type, birth place, new students after school, family income, family, number of children, parents' age, parents' years of schooling may are the influencing factors.
(4) low awareness of migrant workers' school new student related knowledge, and knowledge is relatively single and traditional way, new student school type, birth place, family income, family, number of children, parents' age, parents' years of schooling may be the influencing factors.
5 suggestion
(1) the outbreak of measles in key areas such as families, factories, migrant workers' children's schools and other key populations, such as the low age and the young and middle-aged, should be focused on the control of the family, the factory, the migrant workers' children's school and other key places.
(2) Department of education and health departments to strengthen vaccination certificate management and nursery admission, admission, vaccination certificate inspection work.
(3) combined with the characteristics of the crowd, we should use targeted publicity strategies and ways to improve the awareness rate of vaccination related knowledge in order to promote the vaccination of the population from passive vaccination to active vaccination, and effectively prevent the existence of blank points of measles vaccination.
(4) adjust the immune strategy and refinement work: on the one hand to a solid foundation to carry out targeted immunization, focus groups and the implementation of leak replant immunization strategies suitable for specific populations, on the other hand, we must focus on strengthening the hardware construction, optimization of immunization services, to form an effective, high level of population immunity barrier.
