ABSTRACT
Objective To investigate the pathogens spectrum and epidemiological characteristics of rash and fever illness (RFIs) from January 2010 to December 2017 in Pudong New Area, in order to provide scientific evidence for the prevention and control ofRFIs.Methods Enzyme-linked immunosorbent assay and real-time fluorescence quantitative polymerase chain reaction were used to detect the pathogens of enterovirus, measles virus, rubella virus and others from 2 831 clinical samples, and statistical analysis was performed.Results Pathogens were found in 1 633 samples in total, accounting for 68.59%. The top 4 viruses in the pathogen spectrum were enterovirus (52.54%), measles virus (28.54%), rubella virus (13.04%), and varicella-zoster virus (3.37%). There was significnat difference in the detection rate of rubella pathogens among patients of different genders(P=0.026). In the pathogen spectrum of infections of different age groups, the detection rate of enteroviruses at the age of 3-6 years was higher than that of other age groups. The detection rate of varicella-zoster virus at the age of 6-18 years old was higher than that of other age groups. The detection rate of virus including measles virus, rubella virus, dengue virus and small DNA virus in age of 18 and older was higher than that of other age groups. There was significant difference in the detection rate of pathogens in different age groups (all P<0.05).The incidence of RFIs was the highest in spring (41.52%) and the lowest in winter (15.00%). There was a statistical difference in the detection rate of enterovirus, measles, rubella and dengue virus in different seasons (P<0.05).Conclusions Enteroviruses and measles viruses are the main pathogens leading to RFIs in Pudong New Area, and the activity level of RFIs pathogens should be monitored for a long time.
