ABSTRACT
Objective To summarize the medical rescue work of China emergency medical team in Philippines disaster area by typhoon Haiyan.Methods The rescue experience was summarized by retrospective study.Results A total of 1 831 patients visited the outpatient and emergency departments during those 10 days.According to the rapid risk assessment,the insect borne diseases,acute gastroenteritis infection and hospital infection were the major problems.The medical team took measures such as disinfection,vector control,cleaning up the environment,hospital infection control and providing the safe water to prevent the infectious diseases.Conclusion A sound organization and management system,high -quality members of the medical team,preparing the reasonable rescue plan and epidemic prevention measures,adequate supplies and effective communication were responsible for the success of the medical rescue.It is necessary to establish several international medical rescue teams at the national level.
ABSTRACT
Objective In order to investigate etiology and molecular-epidemiological characteristics of enterovirus associated encephalitis (EAE) in Zhejiang,2008-2012.Method Cerebrospinal fluid and stool specimens were collected from suspected EAE patients,who were admitted to our hospitals.RD and Hep-2 cell lines were used to isolate enterovirus (EV).Serotypes of these EV isolates were identified through neutralization test by using serotype specific anti-sera.VP 1 genes of these isolates were sequenced,compared and used for the construction of phylogenetic tree.Results 127 (20.6％) human enterovirus (HEV) strains were isolated from 616 samples,which were collected from 610 patients.Serotypes of these EV isolates,including 60 coxsackievirus (CV),and 67 Echovirus (E) appeared to be CVA9,CVB1,CVB3-5,E3,E4,E6,E9,El4,E25 and E30,respectively.Predominant EV serotypes on EAE from 2008 to 2012 were seen as CVB3,CVB5,E6,E30 and E30,respectively.The full length of VP1 genes from different EV isolates was between 834 and 918 nucleotides.The VP1 gene similarities between these isolates and the reference strains were from 76.7％ to 85.0％ (nucleotides level) and 91.1％ to 97.9％ (amino acids level).The VP1 genes from E6 serotype isolates appeared most diverged,reaching 20.4％ (nucleotides level) attd 4.8％ (amino acids level).Based on the generated phylogenetic tree,all the EV isolates were fallen on the same branch of HEV-B,and the isolates in the same serotype formed one sub-branch,suggesting there existed geographical and temporal effects.E6 isolates diverged into two branchlets.Conclusion EVs from HEV-B were the etiologic agents for EAE in Zhejiang province from 2008 to 2012.All these EV isolates showed 12 serotypes,with predominant isolates varied every year.E30 was determined as the most dominant serotype while serotype E6 diverged into two sub-genetypes.
ABSTRACT
Objective To study the status on economic burden of diarrhea in Zhejiang province so as to provide evidence for allocation of health resource as well as decision-making on health issues. Methods Multi-phases stratified random cluster sampling was used to select samples in the population. Data was collected on the incidence of diarrhea in the last two weeks as well as on the related cost due to medical care etc. Results The overall incidence (person per year) of diarrhea was 0.26, with 0.29 in the rural and 0.22 in the urban areas respectively. The incidence of diarrhea in children less than 5 was 0.66 (person per year), higher than in any of the age groups. The average direct cost of medical treatment was 69.23 Yuan with average direct cost of non-medical care was 8.29 Yuan for every person, while the indirect cost was 48.43 Yuan. in conclusion, the average disease burden of diarrhea in the province was 1.697 billion Yuan per year, which accounted for 1%o of the GDP, with 1.217 billion Yuan in rural area and 0.480 billion Yuan in the urban areas respectively. The direct cost of medical care was 0.886 billion Yuan (52.21%) and the direct cost due to non-medical care was 0.124 billion Yuan (7.31%). The indirect cost appeared to be 0.480 billion Yuan (40.48%). Factors that affecting the cost would relate to: severity of diarrhea, medical insurance, location of residential area, age and education background of the patients, etc. Conclusion Programs on diarrhea prevention and control should be strengthened to reduce the economic burden caused by this disease while special attention should be paid to those children who are under 5 years of age and living in the rural areas.
