Maps are published here once their data rights are cleared and they have been reviewed. Each shows its time and space reference, its sources and its uncertainty.

Health Nexus released maps are reviewed map views of health and biosecurity, published once their data rights are cleared, each with its coordinate reference, date, sources and uncertainty. Layers draw on sources such as WHO pulse surveys on continuity of essential health services. A map shows released, rights-cleared evidence, not a live feed or an official warning.
How far each division sits from a large city, with the roads and airports that carry patients and supplies, shown for Africa as an example geography for this subject.
