流感是流感病毒引起的一种急性呼吸道传染病,严重危害人群健康.5岁以下儿童作为流感的高危人群,罹患流感后出现严重疾病和死亡的风险较高.目前处于流感病毒流行的冬季,在新冠肺炎疫情流行态势仍在持续的情况下,儿童将面临新冠病毒及流感病毒感染的双重风险.因此,接种流感疫苗预防流感显得尤为必要. 相似文献

Objective: Clinical case definitions used for influenza surveillance among hospitalized patients vary and need systematic evaluation. Design, setting and sample: During July 2009–August 2011, we collected clinical data and specimens (nasal and throat swabs) from rural patients hospitalized for acute medical illnesses. Specimens were tested by rRT‐PCR for influenza viruses. Main outcome measures: Case definitions evaluated the following: influenza‐like illness (ILI: measured fever plus cough or sore throat); severe acute respiratory illness (SARI: ILI with difficulty breathing in ≥5 years, Integrated Management of Childhood Illness–defined pneumonia or severe pneumonia, or physician diagnosed lower respiratory infection in <5 years); acute respiratory infection (ARI: ≥1 of cough, nasal discharge, difficulty breathing or sore throat); febrile acute respiratory illness (FARI: fever plus either cough, sore throat, runny nose, difficulty breathing, or earache). Variants that included “reported fever” and additional sign–symptom combinations were also evaluated. Results: We enrolled 1043 hospitalized patients, including 257 children <5 years of age (range 1 day–86 years). Seventy‐four patients tested influenza virus positive (including 28 A(H1N1)pdm09). Sensitivity(95% CI) and specificity (95% CI) for influenza infection were 78% (67–87) and 60% (57–63) for ILI (measured/reported fever); 37% (26–49) and 78% (75–80) for SARI (measured/reported fever); 82% (72–90) and 57% (54–60) for FARI (measured/reported fever); 88% (78–94) and 45% (42–49) for ARI; and 74% (63–84) and 61% (58–64) for measured/reported fever plus cough. Case definitions including only measured fever had lower sensitivity. Conclusion: ILI and FARI with measured/reported fever provided good balance between sensitivity and specificity among hospitalized patients. The simpler case definition of measured/reported fever plus cough is suited for field surveillance. 相似文献

The aim of this systematic review was to summarise the clinical and epidemiological features of the pandemic influenza A (H1N1) 2009. We did a systematic search of published literature reporting clinical features of laboratory-confirmed pandemic influenza A (H1N1) 2009 from 1 April 2009 to 31 January 2010. Forty-four articles met our inclusion criteria for the review. The calculated weighted mean age of confirmed cases was 18·1 years, with the median ranging from 12 to 44 years. Cough (84·9%), fever (84·7%), headache (66·5%), runny nose (60·1%) and muscle pain (58·1%) were the most common symptoms of confirmed cases. One or more pre-existing chronic medical conditions were found in 18·4% of cases. Almost two-thirds (64%) of cases were aged between 10 and 29 years, 5·1% were aged over 50 years and only 1·1% were aged over 60 years. The confirmed case fatality ratio was 2·9% (95% CI 0·0-6·7%), an extracted average from 12 of 42 studies reporting fatal cases (937 fatal cases among 31,980 confirmed cases), which gives an overall estimated infected case fatality ratio of 0·02%. Early in the pandemic, disease occurred overwhelmingly in children and younger adults, with cough and fever as the most prevalent clinical symptoms of the confirmed cases. A high infection rate in children and young adults, with sparing of the elderly population, has implications for pandemic influenza management and control policies. 相似文献

目的分析云南省住院儿童HIV/AIDS临床特点。方法回顾性分析云南省艾滋病关爱中心2006年1月—2015年12月收治的HIV/AIDS患儿人口学资料、流行病学资料、临床表现及合并症、实验室检查、临床转归等。结果 82例HIV/AIDS患儿中,男47例,女35例。其中93.90%(77/82)通过母婴传播感染HIV。年龄为6~15岁占75.60%(62/82),1~6岁占20.73%(17/82),1岁以下占3.66%(3/82)。体格生长评价显示,39例(47.56%)患儿的身高或体质量处于下等,所有患儿身高不达标更为常见。免疫功能重度抑制者44例(53.66%),中度抑制者16例(19.51%)。该组患儿常见的临床表现为慢性或反复咳嗽51例(62.19%),持续或反复发热47例(57.32%),贫血43例(52.44%),营养不良40例(48.78%)等。主要机会性感染诊断:细菌性肺炎25例(30.49%),结核24例(29.27%),鹅口疮16例(19.51%),其中38%的患儿合并有2种及2种以上机会性感染。治疗后好转77例,未愈死亡5例。结论云南省住院儿童HIV/AIDS感染途径以母婴传播为主,患儿生长发育明显受限,免疫功能严重损害,临床表现复杂多样,疾病进展及合并感染疾病谱与HIV/AIDS成人患者有异,儿童HIV/AIDS早诊断、早治疗十分重要。 相似文献

BACKGROUND: Seroepidemiological studies have revealed that influenza C virus is widely distributed globally. However, because the isolation of this virus is difficult, there have been few reports on its clinical features. METHODS: Between December 1990 and November 2004, 84,946 respiratory-tract specimens were obtained from patients < or = 15 years old. On the basis of the results of isolation of virus, we examined the clinical data on children infected with influenza C virus. RESULTS: Of 170 children infected with influenza C virus, 157 (92.4%) were < 6 years old. Fever (frequency, 90.0%), cough (frequency, 74.1%), and rhinorrhea (frequency, 61.8%) were the most frequent symptoms. The mean duration of fever was 2.88 days (standard deviation, 1.66 days). Of the 170 children, 29 were hospitalized, and 21 (72.4%) of these 29 had lower-respiratory-tract illness such as pneumonia, bronchitis, and bronchiolitis. The rate of hospital admission was significantly higher in children < 2 years old than in children 2-5 years old (30.4% vs. 11.9%; P = .0043). CONCLUSIONS: Influenza C virus is a significant cause of upper-respiratory-tract illness in children < 6 years old, and the risk of complications with lower-respiratory-tract illness is particularly high in children < 2 years old. 相似文献

Summary
We prospectively followed 725 children under 2 years of age with laboratory-diagnosed Bordetella pertussis infection to investigate the hospitalization rate and complications. Diagnosis was made by culture and polymerase chain reaction
(PCR) from nasopharyngeal swabs in 11,016 children who presented with ≥ 7 days of cough at 63 pediatric practices in Germany.
Of these children, 33 (4.5%) were hospitalized at a mean age of 4.8 months (range, 17 days to 19.5 months). Complications
occurred in 16 (48%) of the 33 patients. Pneumonia developed in two (6%) children and a convulsion was observed in one (3%).
Intensive care monitoring was required for 23 (70%) children. Further complications were bradycardia (21%), apnea (12%), conjunctivitis
(12%), loss of weight (12%), otitis media (6%), atelectasis (3%) and dehydration (3%). Children aged 6–24 months who had not
received any dose of pertussis vaccine had a ten-fold increased risk of hospitalization compared to those who had been partially
or fully immunized (p < 0.05). Pertussis immunization should be given at an early point in time and completely in order to
prevent severe courses of pertussis and hospitalization in young children.
