Clinical Validation of the NowFuture Digital Flu / COVID Test in Anterior Nasal Samples for Over-the-Counter (OTC) Use in Australia
Prospective clinical study conducted at three sites (with a simulated home environment) in Australia for the clinical validation of the NowFuture Digital Flu / COVID Test. Results from the investigational test will be compared to results from a highly sensitive reverse transcriptase polymerase chain reaction (RT-PCR) test for SARS-CoV-2, Influenza A and Influenza B. The primary objective of this study is to evaluate the clinical performance (positive percent agreement, negative percent agreement and 95% confidence intervals for upper and lower bounds) of the NowFuture Digital Flu / COVID Test for the qualitative detection and differentiation of SARS-CoV-2 nucleocapsid antigen, Influenza A and Influenza B nucleoproteins antigens using AN swab samples collected and processed in the test by lay users.

Age Related Differences in Respiratory Immune Responses in Influenza Virus Infection
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.
