Objective To study the clinical and the epidemiological features of hospitalized children with influenza virus infection. Methods Two hundred and fifty-three inpatients with laboratory-confirmed influenza virus infection from 1999 to 2008 were reviewed for analyzing the clinical and epidemiological characteristics. Type A and B influenza viruses in the nasopharyngeal aspirates were detected by immunofluorescence assay. Mann-Whitney U test were performed for comparing the median age and the length of hospitalization. Chi-square test was performed for comparing the proportion of patients with fever and cough. Results Among 253 hospitalized children aged between 5 days and 127 months, 182 (71.9%) were boys and 71 (28. 1%) were girls. The median age was 18 months. Fifty-three cases were infants younger than 6 months. 95 cases were children aged between 6 months and 2 years, 85 cases were aged between 2 years and 5 years and 20 cases were older than 5 years. The diagnosis of influenza-related admission included pneumonia (190 cases), bronchitis (49 cases) and upper respiratory tract infection (14 cases). Eleven cases developed febrile convulsion, 6 cases had acute exacerbation of asthma and 3 cases had concomitant viralencephalitis. Twenty-nine cases had basic diseases. Cough and fever were the most common symptoms. Two hundred and thirty-eight cases presenting cough and 209 case presenting fever. Sixty-seven percent (140/209) had high fever with body temperature higher than 39 ℃. The average duration of fever was (5. 0 ±2. 9) days. Fever and cough were both more common in children older than6 months (X2 = 22. 895,P<0. 01; X2 = 16. 992,P<0. 01, respectively). Febrile convulsion occurred in children older than 2 years. Fifteen point five (39/251) developed leukocytopenia. Conclusions Children younger than 5 years old are at high risk of influenza-related hospitalization. We should emphasize influenza vaccination in previously healthy children aged between 6 months and 5 years and children with underlying diseases.

Objective To understand the epidemiology of respiratory syncytial virus(RSV),influenza virus type A and type B(IV-A and IV-B),parainfluenza virus type 1,2,3(PIV-1,2,3)and adenovirus(ADV) among children with acute respiratory tract infection in Shanghai.Methods A retrospective epidemiological investigation was conducted to analyze the prevalence rate,seasonality and susceptible pediatric population of seven common respiratory viruses among hospitalized pediatric patients(<15 years old) with acute respiratory tract infection in Children's Hospital Affiliate to Fudan University Shanghai during 2003 to 2006.Nasopharyngeal aspirates were collected for detecting viral antigens of RSV,IV-A,IV-B,PIV-1,PIV-2,PIV-3 and ADV by direct immunofluorescence assay.Results Total 11214 children were collected during the consecutive four years,among whom 98.7% were presented with acute lower respiratory tract infection.The overall positive detection rate of these seven respiratory viruses was 24.2%.RSV accounted for 17.7%,followed by PIV-3(2.8%),ADV(2.2%),IV-A(0.7%),PIV-I(0.5%),PIV-2(0.3%),IV-B(0.1%)and mixed(0.2%).RSV season often occurred in winter and spring,however,an early season began in autumn every two year.PIV-3,ADV and IV were usually prevalent sporadically and the seasonal patterns were not typical.The median ages of infected pediatric patients were 4 months for RSV,8 months for PIV-3,9.5 months for PIV-1,10.5 months for PIV-2,12 months for ADV,13 months for IV,respectively,which were significantly different by statistical analysis(X2=154.319,P<0.01).The infants and younger children were more susceptible for developing RSV and PIV-3 related diseases.RSV infection significantly decreased along with the age increased.Conclusions RSV is the most commonly identified virus,while infants and neonates are the most susceptible populations for RSV infection.Typically,RSV is prevalent during spring and winter but begins to be active in fall every other year. PIV-3 is found to be the second common viral pathogen and young children are susceptible population.ADV ranks the third pathogen and children with ADV infection tend to be elder. Nevertheless,IV is rare among pediatric population in recent years in Shanghai.In our study,the outbreaks of ADV and IV infections among children are not observed.
