What we watch for — and how.

Zambia's Points of Entry are a front line for early detection. An explainable-AI risk engine evaluates each traveller's declaration against WHO case definitions for 41 priority communicable diseases, and surfaces the reasoning — never a black box.

Explainable by design

Every flag carries its reasoning.

Suspected cases are flagged with the evidence shown — the symptom cluster, exposure history and the IHR (2005) case-definition criteria that drove the score. Border officers and PHEOC epidemiologists can verify and act with clinical confidence.

Syndrome classification mapped to WHO case definitions.
IHR (2005) escalation rules and IDSR alignment.
Human-in-the-loop: the AI advises; a qualified officer decides.

From signal to response

Detect → notify → respond.

Detect

Symptom clusters and exposure patterns are scored in real time as travellers are screened — at the moment of entry, not days later.

Notify

Suspected events raise silent, server-authoritative alerts to exactly the right officers, and roll up to the PHEOC.

Respond

Aggregated, decision-ready surveillance feeds IDSR — so a signal at one border is visible nationally within minutes.
