Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will assist in the early detection of influenza resistant to antivirals and will monitor the clinical outcome of adults and children infected with influenza according to subtype and susceptibility. Participants clinically diagnosed with influenza will undergo a rapid diagnostic test and viral sampling at Baseline and on Days 3, 6, and 10. Participants will be clinically managed according to local guidelines and the decision to treat/not treat will be at the discretion of the Investigator.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Participants Infected with Influenza

Participants with a positive diagnostic test of influenza and/or displaying symptoms suggestive of influenza-like illness will be enrolled and followed for up to 10 days after informed consent for virological surveillance and assessment of clinical outcomes. Participants may receive treatment including oseltamivir, other treatment/medication, or no treatment.

Oseltamivir

Intervention Type DRUG

Participants may receive treatment at the discretion of the investigator according to local practice standards, and there is no protocol-specified intervention. However, analyses will be presented separately for participants treated with oseltamivir during the course of the study.
