Four years after its creation: what role for the Laboratoire des Grandes Épidémies Tropicales (LAGET) in epidemic response in Chad?

Established in 2020 at the height of the COVID-19 pandemic, the Laboratoire des Grandes Épidémies Tropicales (LAGET) was created to strengthen Chad’s capacity for diagnosis, research, and training in the face of emerging infectious diseases. Four years later, this narrative review retraces the laboratory’s main achievements, from its initial structuring to its operational role in epidemic response. Through scientific publications, strategic partnerships, and its commitment to integrated surveillance, LAGET has positioned itself as a key actor within the One Health paradigm in Chad and the Central African region, and it is now part of the laboratory network of the National Public Health Institute of Chad.
