Filter by:The goal of this observational study is to understand immune responses to viral airway infection in adults, including the elderly. The main question(s) to answer is/are: Why do some individuals acquire only asymptomatic or mild Influenza A virus (IAV) infection while others become severely ill and even succumb to the same disease? Participants will be asked to donate samples when seeking health care for influenza-like symptoms or if hospitalized for IAV or SARS-CoV-2. Samples asked for are: - Blood sample by venepuncture - Blood sample by capillary sampling - Nasopharyngeal aspirate - Nasopharyngeal swab - Endotracheal tube aspirate - Nasal swab - Nasal curette - Breath Explor (sampling of expired air) Researchers will compare obtained results with the same type of samples from healthy controls.
Respiratory Syncytial Virus (RSV) is a seasonal, highly contagious pathogen belonging to the Pneumoviridae (genus orthopneumovirus), a family of negative-strand RNA viruses. Lung ultrasonography; Today, it has become frequently used in neonatal intensive care units because it is a diagnostic, useful, harmless, radiation-free, bedside, reproducible and practical method. The primary purpose of the study is to record lung ultrasound findings and score and thus to compare the agreement between lung ultrasonography and clinical score in the diagnosis and follow-up of newborn babies who are followed up in the neonatal intensive care unit due to bronchiolitis caused by RSV and other viral factors, which are frequently encountered.
The study will be a multicenter, hospital-based retrospective study. We plan to collect the clinical and laboratory data among all hospitalized ARTI cases in three hospitals in Wuhan from June 1, 2020 to May 31, 2023 and then analyze the epidemiological and clinical characteristics of RSV infection, clarify the gene types of epidemics under 5 years old children after the outbreak in Wuhan, China.
