“…There were a few clinical reports about a varies of respiratory infection patients. However, in these studies, the proportion of patients with respiratory symptoms undergoing chest CT examinations did not exceed 20% and, furthermore, the patients were not randomized into groups ( 12 , 16 , 23 – 25 ). Whereas the limitations of previously research, this study conducted a comprehensive collection of chest CT data for patients with influenza-like symptoms and compared the difference of normal and abnormal chest CT cases.…”

Background: This study was to collect clinical features and computed tomography (CT) findings of Influenza-Like Illness (ILI) cases, and to evaluate the correlation between clinical data and the abnormal chest CT in patients with the Influenza-Like Illness symptoms.Methods: Patients with the Influenza-Like Illness symptoms who attended the emergency department of The Six Medical Center of The PLA General Hospital from February 10 to April 1, 2020 were enrolled. Clinical and imaging data of the enrolled patients were collected and analyzed. The association between clinical characteristics and abnormal chest CT was also analyzed.Results: A total of 148 cases were enrolled in this study. Abnormalities on chest CT were detected in 61/148 (41.2%) patients. The most common abnormal CT features were as follows: patchy consolidation 22/61(36.1%), ground-glass opacities 21/61(34.4%), multifocal consolidations 17/61(27.9%). The advanced age and underlying diseases were significantly associated with abnormal chest CT.Conclusions: Abnormal chest CT is a common condition in Influenza-Like Illness cases. The presence of advanced age and concurrent underlying diseases is significantly associated with abnormal chest CT findings in patients with ILI symptoms. The chest CT characteristic of ILI is different from the manifestation of COVID-19 infection, which is helpful for differential diagnosis.

“…Cabe destacar que, tal y como refieren otros estudios no existen prácticamente diferencias en la afectación por géneros (9) . En relación con los antecedentes patológicos de interés, nuestro estudio muestra que aproximadamente un 90% de los pacientes padecía algún antecedente, dato por encima de los estudios previos, que muestran un porcentaje alrededor del 70% (10) . Los antecedentes de etiología cardíaca resultan mayores en incidencia en nuestro estudio, seguido de la patología respiratoria y renal.…”

Introducción: El virus de la gripe ocasiona anualmente epidemias estacionales con amplia extensión mundial y se estima que entre el 5 y el 20% de la población padece gripe cada año. En abril de 2009 se confirmaron los primeros casos de infección humana causados por un nuevo virus de la gripe A (H1N1). Objetivo y Método: En el período de epidemia (semana 40-20) del 2016-2018 se realizó un estudio observacional descriptivo prospectivo multicéntrico en dos hospitales públicos del área metropolitana sur de Barcelona con el objetivo de determinar la incidencia de pacientes positivos en gripe A (H1N1), así como las características demográficas y clínico-evolutivas de estos pacientes, la temporalidad en la detección del virus y medidas aplicadas por control de la infección.Resultados: Los resultados del presente trabajo indican que la incidencia acumulada de Gripe A durante el periodo de estudio fue de 233,68 casos por cada 100.000 habitantes. Casi el 90% de los pacientes padecía antecedentes patológicos siendo los más prevalentes la patología cardíaca y respiratoria. Además, el 40% de los pacientes hospitalizados presentó complicaciones, principalmente la neumonía. El tratamiento y días de aislamiento fueron según los estándares recomendados. Conclusión: Estos hallazgos muestran la elevada incidencia de gripe A, así como los beneficios de que los equipos de control de la infección realicen el seguimiento del cumplimiento del tratamiento y medidas para evitar la transmisión. Introduction:The influenza virus causes seasonal epidemics worldwide and it is estimated that between 5 and 20% of the population suffers from influenza each year. The first cases of human infection caused by a new influenza A virus (H1N1) were confirmed in April 2009.Objective and Method: In the epidemic period (week 40-20) of 2016-2018, a multicenter prospective descriptive observational study was carried out in two public hospitals in the southern metropolitan area of Barcelona in order to determine the incidence of positive patients in influenza A (H1N1), as well as the demographic and clinical-evolutionary characteristics of these patients, the timing of virus detection and measures applied for infection control.Results: The results of the present work indicate that the cumulative incidence of Influenza A during the study period was 233,68 per 100,000 inhabitants. Almost 90% of the patients had an underlying chronic condition, mostly heart disease and respiratory pathology. Furthermore, 40% of the patients presented complications, mainly pneumonia. Treatment and days of isolation were according to standard recommendations. Conclusion: These findings show the high incidence of influenza A virus (N1H1) as well as the benefits that apports the infection control teams surveillance, monitoring the compliance with treatment and days of measures to avoid the transmission.

“…Although data on risk factors for influenza are key to guide targeted influenza vaccination, few studies have addressed topics on the risk factors for influenza [95][96][97][98][99] . Results from these studies reported that underlying medical conditions such as HIV, tuberculosis, diabetes, chronic respiratory diseases, pregnancy and patient's age contribute strongly to influenza associated hospitalization or death.…”

“…Moreover, Barakat et al in Morocco found that influenza cases associated with hypertension (aOR, 28.2), neurological disorders (aOR), obesity (aOR, 7.1), as well as pregnancy (aOR, 2.5) were at increased risk of death 96 . Furthermore, Bouneb et al in Tunisia using logical regression reported that acute respiratory distress syndrome (ARDS) (OR = 27; 95%CI: 3.62-203.78) was the only factor significantly associated with severe outcomes of influenza cases 99 . Influenza associated co-morbidities have been studied nine articles from 3 countries 101-105, 107-109, 134, 215 .…”

Background: Influenza infection is a serious public health problem that causes an estimated 3 to 5 million cases and 250,000 deaths worldwide every year. The epidemiology of influenza is well-documented in high- and middle-income countries, however minimal effort had been made to understand the epidemiology, burden and seasonality of influenza in Africa. This study aims to assess the state of knowledge of seasonal influenza epidemiology in Africa and identify potential data gaps for policy formulation following the 2009 pandemic. Method: We reviewed articles from Africa published into four databases namely: MEDLINE (PubMed), Google Scholar, Cochrane Library and Scientific Research Publishing from 2010 to 2019. Results: We screened titles and abstracts of 2070 studies of which 311 were selected for full content evaluation and 199 studies were considered. Selected articles varied substantially on the basis of the topics they addressed covering the field of influenza surveillance (n=80); influenza risk factors and co-morbidities (n=15); influenza burden (n=37); influenza vaccina- tion (n=40); influenza and other respiratory pathogens (n=22) and influenza diagnosis (n=5). Conclusion: Significant progress has been made since the last pandemic in understanding the influenza epidemiology in Africa. However, efforts still remain for most countries to have sufficient data to allow countries to prioritize strategies for influenza prevention and control. Keywords: Influenza; epidemiology; review; Africa; post pandemic.
