View clinical trials related to Influenza Type A.
Filter by:Collection of Nasal Swabs, Throat Swabs and Saliva Samples from patients presenting at their designated care or testing facility displaying symptoms of either Influenza, Respiratory Syncytial Virus (RSV), SARS-CoV-2 or those who have been in recent contact with SARS-CoV-2 positive patients. Collected samples will aid the development, calibration and performance evaluation of the LumiraDx POC Test.
Influenza causes substantial morbidity and mortality worldwide despite available antivirals and vaccines. SAB Biotherapeutics, Inc. has developed SAB-176, an anti-influenza human immunoglobulin (transchromosomic [Tc] bovine-derived) intravenous therapeutic to treat past and current strains of Type A Influenza and Type B Influenza. This study will evaluate the safety, tolerability, and pharmacokinetics of SAB-176 in healthy participants.
Prospective clinical study on the performance of an Influenza A+B rapid test kit. The main goal is to establish the sensitivity and specificity (i.e. how accurate the test is) when compared to a gold standard. Option of participating in this clinical study will be presented to patients displaying influenza-like illness. Informed consent will be collected from patients or patient's next of kin/guardian before samples (nasopharyngeal swab) are taken from the patient. Nasopharyngeal swabs are tested using both the investigational test kit and a predicate fluorescence immunoassay test kit. All samples will be tested using a molecular-based PCR test kit as a confirmatory test. The results will be analysed statistically and the performance of the Influenza A+B test kit can be evaluated.
The surveillance of influenza virus among children with febrile reparatory complaints attending the pediatric clinic in Shantou is an epidemiologic study to identify the type (influenza A or B) and the subtype of Influenza A of the isolates from children with febrile respiratory complaints who attend the pediatric clinic of the first Affiliated Hospital, Shantou University Medical College, Shantou Guangdong, China. Also this study investigates the genetic composition of all segments of isolated strains using standard molecular techniques and to make available the new strains of influenza viruses isolated from such children for the formulation of influenza vaccines. Clinical manifestation of the respiratory illness is recorded and single nasopharyngeal swab is obtained from eligible children. Viral culture is performed on the nasopharyngeal secretions. If influenza is isolated, this is characterized if it belongs to influenza A or B. If the virus is characterized as influenza A, further antigenic studies is done to determine subtype of influenza. Viral isolates is further studied to determine the genetic composition of the virus. Information obtained from the viral isolates is shared with the WHO and the CDC.
