Study of Viral Respiratory Infections
Condition(s) studied
Study summary
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.
Eligibility
Primary outcome measure(s)
- Identify potential changes in the circulation of major respiratory viruses (FLUA, FLUB, VRS, AdV, PIV, MPV, RV) during the period 2018-2023. — From 2018 to 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.
