About

This observational study will investigate suspected infectious diseases of unknown etiology prospectively during outbreaks and at healthcare facilities, and retrospectively through historical samples where no etiology was ever determined. The study is designed to rapidly, flexibly, and consistently respond to any potential scenario in Indonesia, and the data collected will provide needed insight into the landscape of infectious diseases in the country. By better understanding the infectious causes of outbreaks and difficult hospitalized cases, the Indonesian Ministry of Health will be able to more accurately and efficiently control infectious diseases and craft healthcare policies.

Full description

This is a study to identify the causative agents and describe the clinical characteristics of infectious disease outbreaks and difficult cases of unidentified etiology in Indonesia. It is a retrospective and prospective observational study with an exploratory design. There will be no intervention to the participants that is intended to affect their SoC or clinical outcome.

Retrospective study activities will be ongoing throughout the duration of the study. The INA-RESPOND Reference Lab will perform research tests on various specimens collected as part of historical outbreaks and previous difficult cases where an etiology was never identified.

Prospective study activities will be initiated upon official request from health authorities and health facilities/institutions. Requests are expected to be filtered through and evaluated by the 19 active INA-RESPOND Network sites before inclusion in the study. Samples collected during outbreaks and from difficult cases of unknown etiology will be analyzed at the INA-RESPOND Reference Lab at their own pace. Results from any research tests will be shared with the requesting authorities as research-use-only and are not intended to alter standard of care.
