Kenyan volunteers track polio in remote north through rumour and trust

A network of community health workers and wastewater monitoring detects poliovirus before it spreads in Kenya's underserved regions.

• Health officials routinely test wastewater in Nairobi for traces of poliovirus, often detecting it before symptoms appear.
• Community health volunteer Eroi Lemarkat investigates reports of acute flaccid paralysis in remote settlements, racing to collect stool samples within 14 days of onset.
• Dr Galm Glelo, the Ministry of Health's polio surveillance point person, stated that information gathered by volunteers enables quick targeted interventions.
• Dr Emmanuel Okunga said nomadic pastoralists frequently cross borders, complicating surveillance, and that cross-border coordination is essential.
