ABSTRACT
Abstract@#Tuberculosis (TB) prevention and control in schools is always the key area of TB control work. The paper reviews the TB epidemic change trend and characteristic in students, and analyzes existing problems in current TB control work in schools, including incompletely implemented routine precaution measurements in schools, inaccurate occupational information for TB patients, absence of evidence from TB laboratory in diagnosis and tracing infectious source, lack of timeliness and standardization in close contact screening, low coverage of preventive therapy, and lack of capacity for tackling public sentiment. Specific suggestions were proposed for every institute involved in TB control work in schools to solve these problems.
ABSTRACT
Objective@#To estimate the transmission capacity of influenza clustering in schools and nurseries, and to evaluate the effect of suspension measures, providing a basis for formulating disease management strategies and control measures.@*Methods@#The SEIAR dynamics model was used to simulate the epidemic data, calculating the basic regeneration coefficient R 0 of the epidemic to evaluate the epidemic transmission capacity, and calculating the cumulative incidence rate of the epidemic to evaluate the prevention and control effect of the suspension measures.@*Results@#The basic regeneration coefficient R 0 was 8.44(8.01,8.89) without intervention. There were statistically significant differences in R 0 of influenza epidemic among different types of school(F=9.52, P<0.01). The R 0 of influenza epidemic in primary and secondary schools were higher than that in nurseries(P<0.05). R 0 of influenza A was higher than that of influenza B(t=2.71, P<0.01). R 0 of influenza A(H3) was higher than of influenza B(Victoria)(P<0.05). The cumulative incidence of the outbreaks which were suspended for 4 days and 7 days was significantly lower than that in the non-suspensions(P<0.05). However, there was no significant difference in the cumulative incidence of the outbreaks between the 4-day suspension and the 7-day suspension(P>0.05).@*Conclusion@#Transmission capacity of school-based influenza epidemic is high, especially among primary and secondary schools. When the epidemic situation of infected class meets the suspension standard, it is recommended to suspend classes for 4 days.
ABSTRACT
Abstract@#In recent years, school-based sexuality education was attached with great importance by more and more countries and educators. However, in China, the implementation and promotion of school-based sexuality education is still facing a number of challenges, including course/class hours, teaching materials, training of teachers as well as the collaboration among schools, families and communities, etc. This paper aims to learn from advanced experience of sexuality education in Macau, in order to promote the development of school-based sexuality education in Mainland China.
ABSTRACT
Objective@#To investigate the current situation of the installation and use of air purification equipment in primary schools in Beijing in order to provide data for school-based air pollution prevention and intervention.@*Methods@#A questionnaire survey was conducted in 50 primary schools in 6 districts in Beijing. Spearman correlation coefficient and Pearson correlation coefficient were used to test the correlation between installation rate of air purification equipment and per capita disposable income.@*Results@#The overall installation rate of air purifier or fresh air system in primary schools in Beijing was 62.0%, the overall installation rate of air purifier was 50.0% and the overall installation rate of fresh air system was 18.0%. Installation rate of fresh air system or air purifier was highly correlated with per capita disposable income (r=0.92, P=0.01).@*Conclusion@#The installation rate of air purification equipment in primary schools is relatively high, but parameters and purification types are not unified, and there is a lack of scientific guideline. Therefore, the installation and use of air purification equipment in schools should be further standardized and unified to protect the health of children and adolescents.
ABSTRACT
Objective@#To understand the distribution of tobacco point-of-purchase(pop) activies 100 meters around the primary and middle school and the situation of selling cigarettes to students of Tianjin. To provide evidence for creating a smoke-free and healthy school environment.@*Methods@#With the method of simple random sampling, 195 schools were selected to investigate the tobacco retailers within 100 meters around the school, and the nearest tobacco retailers was observed.@*Results@#Totally 36.9 percent of the schools found tobacco retailers within 100 meters. There were 127 tobacco retailers, and no tobacco advertisements were found. The percentage of tobacco retailers within 100 meters of vocational schools, primary schools and middle schools was 33.3%, 34.1% and 40.4%, respectively. Among the 72 tobacco retailers observed, the proportion of tobacco retailers within 20, 21-50, and 51-100 meters from the school were 9.7%, 36.1% and 54.2%, respectively. The majority of tobacco retailers were grocery stores/convenience stores (55.6%), followed by alcohol and tobacco stores (34.7%). The proportion of tobacco selling points failing to set up the signs of "smoking harmful to health" and "not selling cigarettes to minors" were 81.9% and 86.1% respectively.@*Conclusion@#It’s concerning that the layout of tobacco retailers and the posting of signs, and the tobacco products for to minors in Tianjin. It is necessary to strengthen the surrounding environment renovation and publicity and law enforcement.
ABSTRACT
Objective@#To understand reason for the difference of supplementary immunization activities (SIA) using measles-containing vacline (MV) among different types of universities in China.@*Methods@#Ten universities from one city were selected by using purposive sampling method. Qualitative interviews were conducted on the implementation of MV SIA in universities, and the differences of measles vaccination and the reasons were analyzed.@*Results@#The MV vaccination rates in the 10 universities in 2017 were 54%, 96%,95%,97%,81%,93%,13%,12%,10% and 21% respectively.The rate of four-year universities was higher than that of three-year colleges; and the rate of public universities was higher than that of private schools; the rate of provincial universities was higher than that of central government administered universities; the vaccination rates also vary within central government administered universities.The level, ownership and affiliation of colleges and universities led to the differences in medical qualification, administrators’ risk perception of disease and vaccines, and the relationship between the schools and local CDC, which in turn affected the implementation of vaccination in universities.@*Conclusion@#The different attributes of universities are the fundamental reasons that lead to the differences in the rate of MV SIA in Chinese universities. It is suggested that the differences of university attributes should be considered in the process of implementation of the policy of immunization in universities.And the vaccination policy in universities should be strengthened, the risk communication of universities, especially private universities, should be improved, and the working relationship of the Ministry of Health and the Ministry of Education should be enhanced.
ABSTRACT
Objective@#To understand prevention and control of infectious disease among primary schools in Xi’an. @*Methods@#A total of 93 primary schools were selected through multi-stage stratified sampling method from 14 counties in Xi’an, then these schools are surveyed to meaure the classroom ventilation.@*Results@#About 28.0% (26/93) of these schools met the national standard for health staffs, with 7.4%(4/54) in urban primary schools and 56.4% in rural primary schools (22/39), the difference between urban and rural areas is statistically significant(P<0.01). Urban primary schools were better than rural primary schools in morning inspection, registration and tracking for illness, verification of vaccination certificates, surveillance and reporting of epidemic outbreaks, verification of school recovery(P<0.05). The average per capita area among the 92 primary schools was (1.22±0.34) m2, with (1.08±0.26) m2 in urban primary schools and (1.42±0.33) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01). The average per capita ventilation area of 92 primary schools was (0.15±0.07) m2 with (0.13±0.04) m2 in urban primary schools and (0.19±0.08) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01).@*Conclusion@#School-based infectious diseases prevention and control needs to be improved in Xi’an, especially in health personnel. Urban schools appear superior in the prevention and control of infectious diseases and sanitary conditions, while rural schools appear superior in student density and classroom ventilation.
