Acute viral respiratory infections are a major public health problem, as they cause mortality especially in pediatric patients, over 65 and those with co-morbidities. The most frequently responsible viruses are: Influenza A and B, Respiratory Syncytial Virus, Adenovirus, Parainfluenza Virus, Metapneumovirus, Rhinovirus and SARS-CoV-2. By comparing clinical data and laboratory diagnosis among all categories of patients at greatest risk, it is possible to define the symptoms associated with the pathogen and establish which etiological agents could be able to cause clinical pictures characteristics of a given type of patient. The study will also provide information on the potential role that simultaneously detected pathogens may play in determining the severity of the clinical picture. In addition, the results will allow to deepen the changes in seasonality and spread of different respiratory viruses associated with the COVID-19 pandemic.
The aim of the study is:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Adult patients | Adult patients with request for the detection of major respiratory viruses (FLUA, FLUB, VRS, AdV, PIV, MPV, RV and SARS-CoV-2). | ||
| Pediatric patients | Pediatric patients with request for the screening of major respiratory viruses (FLUA, FLUB, VRS, AdV, PIV, MPV, RV and SARS-CoV-2). |

| Measure | Description | Time Frame |
|---|---|---|
| Identify potential changes in the circulation of major respiratory viruses (FLUA, FLUB, VRS, AdV, PIV, MPV, RV) during the period 2018-2023. | Requests for the detection of respiratory viruses (FLUA, FLUB, VRS, AdV, PIV, MPV, RV and SARS-CoV-2) will be selected for virological diagnosis received from 2018.09.01 to 2023.08.31 and related to adult and pediatric patients at Hospitals and sampling points in the Metropolitan area of Bologna.The percentage of positive cases (positive number/ total requested) will be calculated for weeks during the study period. The comparison of the positivity found in different epidemic seasons will be performed: first (epidemic season 2018-2019), during (epidemic seasons 2019-2020, 2020-2021, 2021-2022) and after the COVID-19 pandemic (epidemic season 2022-2023) for each pathogen studied. We expect to observe differences in the frequency of each pathogen in the different weeks of the epidemic seasons 2018-2023. | From 2018 to 2023 |
| Measure | Description | Time Frame |
|---|---|---|
| Define the potential role that each pathogen may have in the onset and outcome of certain clinical conditions (symptoms and clinical signs) in adult and pediatric patients | The applications for virological diagnosis (FLUA, FLUB, VRS, AdV, PIV, MPV, RV and SARS-CoV-2) received during the last epidemic season (2022-2023) will be selected and relate to adult and pediatric patients of the Policlinico di S. Orsola. For each of the selected cases, data on the patient's clinical characteristics and laboratory tests will be retrieved. These data will be related to the positive findings for the viruses listed above, by means of virological diagnosis on respiratory material. In addition, the results obtained in the different categories of patients (pediatric, adult, fragile for comorbidities) will be used for the association between viral pathogens detected individually or in packaging in respiratory material and: type of symptoms/clinical outcome; type of clinical signs detectable with objective/instrumental examinations; degree of severity of the clinical manifestation. |
| Measure | Description | Time Frame |
|---|---|---|
| Assess the clinical utility of performing a correct and timely virological diagnosis in terms of reducing antibiotic therapy prescription and instrumental investigations in pediatric patients | The applications for virological diagnosis (FLUA, FLUB, VRS, AdV, PIV, MPV, RV and SARS-CoV-2) received in the last epidemic season (2022-2023) and related to pediatric patients at the Policlinico di S. Orsola will be selected. For each of the selected cases, clinical and laboratory data will be retrieved. In particular, based on the diagnostic care process provided at the departments involved in the study, for patients with clinical signs that suggested the prescription of antibiotic therapy, this therapy was still prescribed, Administered only if the virus tested for is negative. For patients with factors that exposed them to risk of severe respiratory disease (age <2 years, co-morbidity) and with clinical signs that suggested the prescription of antibiotic therapy, this therapy was given and then discontinued only if the virus tested for was not found. The aim is to reduce, in pediatric patients, the prescription of instrumental investigations (RX/ecoaddome) and reduction in the pr |
