Sudan Tries to Contain Polio Outbreak With Nationwide Child Vaccination Drive Amid War
Sudan’s health authorities have launched a polio vaccination campaign for children as conflict hampers access to care and fuels the spread of a variant poliovirus. With six infections already confirmed and the virus detected in wastewater, health workers supported by WHO and UNICEF are racing to reach millions of children across front lines.
Sudan’s battered health system is facing a new test as it tries to stop a crippling virus spreading among children while war continues around them.
The health ministry has announced a nationwide campaign to vaccinate children against polio after confirming an outbreak of a variant poliovirus. Officials say six children have already been infected. Testing has also found the virus in three wastewater sites, showing that transmission is broader than the known clinical cases.
The campaign is backed by the World Health Organization and UNICEF. It aims to reach children in areas held by different armed actors, at a time when fighting has damaged hospitals, disrupted supply lines and displaced large numbers of families.
Polio attacks the nervous system and can cause permanent paralysis, mainly in children under five. In crowded displacement camps and neighbourhoods where sanitation has broken down, the virus can spread quickly through contaminated water and poor hygiene.
For health workers, this campaign means negotiating access, crossing checkpoints and keeping vaccines cold despite fuel shortages and insecurity. In some districts the same roads needed to deliver doses are used by armed convoys or are cut off entirely, forcing teams to find alternative routes or accept gaps in coverage.
Sudan shares borders with several countries that have their own security and public health challenges. Incomplete immunisation inside Sudan raises the risk of poliovirus crossing into neighbouring states via refugees and informal trade, turning a national outbreak into a regional problem.
The outcome of the drive will depend on whether violence eases in key regions long enough for vaccination teams to move, how quickly funding and supplies arrive, and whether local commanders on all sides allow health workers to operate without interference.
Observers will be watching for updated figures on how many children are reached, any new paralysis cases linked to polio, and wastewater testing results both within Sudan and in nearby border towns. Those data points will show whether the campaign is keeping ahead of the virus or falling behind it.
