WHO supports Sudan to re-establish the National Polio Laboratory
Country: Sudan Source: World Health Organization 16 September 2026, Khartoum, Sudan – The National Polio Laboratory in Port Sudan was re-established in June 2026, following the provision of equipment, supplies and training by the World Health Organization (WHO), in close coordination with the Federal Ministry of Health. This marks an important milestone towards restoring the country’s laboratory capacity to detect poliovirus and further strengthens the country’s polio surveillance system, which has been disrupted by the conflict that began in April 2023. “Swift and accurate testing for poliovirus is critical to ending the ongoing polio outbreak in Sudan; and by reactivating the National Polio Laboratory, we are getting closer to this goal. Sudan has ended polio outbreaks before and can do it again,” said WHO Representative Dr Abdinasir Abubakar. “With the strong leadership of the Federal Ministry of Health to end polio, WHO will continue to provide technical and financial support to strengthen laboratory and surveillance capacity in Sudan.” Over the last nine months, WHO has provided critical laboratory equipment, supplies and reagents to the National Polio Laboratory, and a team of experts from WHO and the VACSERA Regional Reference Laboratory in Egypt trained six laboratory personnel to prepare and test stool samples for poliovirus, in line with Global Polio Laboratory Network standards. Previously, all poliovirus samples were transported by road to Egypt and tested at VACSERA. The National Polio Laboratory began testing stool samples from acute flaccid paralysis cases in July 2026. During an initial transition period of a year, stool samples will also be transferred to VACSERA for parallel testing to ensure the quality of testing, and for additional tests to determine the origin of poliovirus in positive samples. This phased approach will strengthen the quality assurance of testing in Sudan, and support the laboratory’s progress towards WHO accreditation, further reinforcing Sudan's capacity to promptly detect and respond to poliovirus. Wastewater samples will continue to be tested at VACSERA until the laboratory’s capacity and space is upscaled to accommodate this service. “The reactivation of the National Polio Laboratory is an integral part of the government’s political commitment to advance recovery of Sudan’s health system and a crucial milestone in our journey towards a polio-free Sudan,” said His Excellency Dr Haitham Mohammed Ibrahim, Federal Minister of Health. “We are grateful for WHO’s support in developing the capacity of our institutions and health workers.” Sudan has confirmed variant poliovirus type 2 (cVDPV2) in five children and three wastewater samples this year. The samples were collected through ongoing surveillance efforts to detect poliovirus swiftly, enabling a rapid response to avoid any further spread. Poliomyelitis is a highly infectious viral disease that largely affects children under 15 years of age. The virus is transmitted by person-to-person spread, mainly through the faecal-oral route or, less frequently, through contaminated water or food, and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.
