Prospective Surveillance of Febrile Illness for Dengue-Endemic Areas in Asia

• Sponsor: Sanofi
• Information provided by (Responsible Party): Sanofi

Study Description

Brief Summary:

The purpose of this study is to detect acute febrile episodes and dengue infection in five Asian countries, to assess dengue seroprevalence, and to assess surveillance infrastructure at investigational sites in anticipation of a Phase 3 efficacy trial of a vaccine to prevent dengue infection.

The primary objectives are:

• To identify acute febrile episodes among the cohort in order to detect the presence of dengue infection.
• To develop operational infrastructure for potential Phase III dengue efficacy trial sites.
• To describe the dengue seroprevalence among the cohort at baseline and at the end of the study.

Condition or disease
Dengue Fever; Fever

Detailed Description:

All participants will make two visits to a study site, an enrollment visit and a termination visit. Additional visits will be made if febrile episodes occur: an acute visit and a convalescent visit. Participants or their parents/guardians will be contacted weekly to monitor the occurrence of febrile episodes and ensure appropriate assessment and care.

No vaccine will be provided or administered in this study.
