Pakistan Reports 15th Polio Case of 2024 from Kharan

The National Emergency Operations Centre confirmed Pakistan's 15th wild poliovirus case of 2024, in a child from Kharan district in Balochistan.

Why Kharan is significant

Balochistan's polio history has been dominated by the Quetta block — Quetta, Killa Abdullah and Chaman. Kharan sits well outside it, in the sparsely populated south-west of the province. A case there indicated that 2024's transmission was not confined to the historical reservoir but had moved into districts that had been quiet.

That pattern held for the rest of the year. Balochistan ended 2024 with 27 cases — the highest of any province — spread across a much wider set of districts than in previous years.

What makes districts like Kharan difficult

Low population density is not an advantage for a vaccination campaign. Settlements are widely separated, travel between them is slow, health infrastructure is thin, and routine immunisation coverage is correspondingly low. A team can spend a full day reaching a handful of households. Mobile and pastoral populations add further difficulty, because a microplan built on fixed households misses families who move seasonally.

The result is that sparsely populated districts can carry immunity gaps as serious as any crowded city, but with far less visibility — fewer environmental surveillance sites, fewer health facilities reporting paralysis cases, and longer delays before a problem is detected.

The response

Confirmation triggers the standard outbreak protocol: emergency house-to-house vaccination across the affected union council and its neighbours, investigation of the child's vaccination history, an active search for other paralysis cases, and expanded environmental sampling to establish how widely the virus has already travelled.

What this case shows about 2024

Pakistan recorded 74 cases in 2024, against six in 2023. A twelvefold increase on that scale does not come from one district failing — it comes from population immunity falling across a wide area at the same time, allowing virus that had been circulating quietly to surface in places that had looked clear.

For parents in Balochistan

Every child under five needs two drops in every round, however remote the settlement and however recently the last team called. Complete the routine immunisation schedule as well — campaigns supplement it, they do not replace it. If no team arrives, call 1166.
