Brief Summary

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

This is a global, multi-center, observational registry of participants with suspected or confirmed infection with avian influenza A H5N1. Data are collected through retrospective abstraction, from detailed case reports that may be published and available in the public domain, or as incident cases received directly from the treating physician or other medical personnel.

Study Groups

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

Avian influenza A

Natural history of Avian influenza A, particularly H5N1 strain which has a high potential of causing a global human pandemic, and real-world treatment practices will be observed in this study. This registry program will not require, recommend, or provide any specific treatment or medications.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants who develop influenza-like symptoms and who are considered to be epidemiologically linked by time, place, and exposure to a probable or confirmed avian influenza or human case of H5N1 infection are eligible for inclusion in the Registry. Cases with atypical symptom presentation (e.g., non-respiratory) are also included, in keeping with evolving knowledge about the clinical presentation of avian influenza.
* Participants with documented positive serological test who either remain asymptomatic or experience mild illness only
* Participants with laboratory confirmation of infection with influenza A (H5N1) who survive long enough to present for medical care
