Study on the public health emergent events in Fujian province in 2004-2007 / 中华流行病学杂志

Objeetive To study the public health emergent events(PHEE)in Fujian province，from 2004 to 2007.Methods Descriptive and analytic methods were Used to analyze the PHEE in Fujian province aecording to the internet.based surveillance reports.Results From 2004 to 2007.there were 304 emergency events being surveyed.Of all the events，there were 7(2.30％)belonged to serious-degree of grade II，57(18.75％)to gradeⅢand 240(78.95％)t0 gradeⅣ，but with no grade I.Results showed that the attack rate in affected population WaS 25.82‰.the mortality rate was 0.08‰and the fatalky rate Was 0.32％.The numbers of emergency events decreased 2.82％on average.each year.A total number of 169(55.60％)events occurred in schools with 71(23.36％)in the countryside.Numbers due to infectious disease-born Was 233(76.64％)including avian flu，cholera and dengue fever were predominant pathogens of the grade II and grade emergency events.57(18.75％)of the events was due to food poisoning.The epi.garph showed that there were two peaks.I.e.in Mar-Apr and Sep.contributed 43.1％to the total number of events.Conclusion Emergency events showed a stable decrease in FujJan province with communicable disease and food poisoning the two major sources and more commonly seen in schools and countryside.We suggest that the government and community pay more attention to the emergency events of avian flu,cholera and dengue fever.

Study on the epidemiology and etiologic agent of Dengue fever outbreaks in Fuzhou in 2004 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.</p><p><b>METHODS</b>Data on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody. The sources of infection were traced by nucleotide sequencing.</p><p><b>RESULTS</b>During the epidemic, 93 cases occured consistently with the region entomoplily growth and decay. The viruses of 6 strains isolated from 10 patients' blood specimens were identified as dengue virus type 1. Phylogenetic evidence suggested that the viral isolate had high genetic relation with the isolates from Kampuchea (DENV-1/KHM/2001; GenBank Accession No. L0904278).</p><p><b>CONCLUSION</b>The epidemic was caused by introduction of patients migrating into Fuzhou.</p>
