Eighty years of building other countries' public health systems

The CDC is described as **a global leader that works with governments to
build, modernise and strengthen public health programmes**, with **80 years of
experience** strengthening the health systems that **detect, prevent and
respond to health threats**.

The three verbs matter in that order. Detection comes first because an
outbreak nobody identifies cannot be prevented or responded to anywhere —
including in the United States.

Six regional offices

The agency operates six regional offices worldwide, among them:

• Caribbean and Central America
• East Asia / Pacific

Regional offices exist because disease surveillance is a regional problem. A
pathogen crossing a border is a shared concern between neighbours long before
it becomes a global one, and the laboratory capacity and reporting systems
that catch it have to work across those borders.

The stated limit

**CDC direct engagement is only in countries with established U.S.
diplomatic relations.**

That single footnote is the honest boundary of the whole programme. Global
health capacity-building is not neutral infrastructure delivered wherever it is
needed — it follows the diplomatic map.

Which means the gaps in that map are gaps in surveillance too. A country with
no diplomatic relationship still has outbreaks, and they still travel.
