Implementation of an infection prevention and control response strategy to combat the Sudan Virus Disease outbreak in an urban setting, the Kampala Metropolitan area, Uganda, 2022.

BACKGROUND

In October 2022, the Uganda Ministry of Health (MoH) confirmed the first case of a Sudan Virus Disease (SVD) outbreak in the Kampala Metropolitan area (KMA). A multicomponent infection prevention and control (IPC) strategy was implemented to control the spread of Orthoebolavirus sudanense (SUDV) in KMA. We describe the deployment of this strategy, its effect on IPC capacities, and the successful control of the SVD outbreak in KMA during the 2022 outbreak.

METHODOLOGY: The multicomponent IPC strategy included (1) IPC pillar coordination: an IPC task force convened by government and health partner representatives and designated focal persons at the district level (2) Ring IPC: intense and targeted IPC support was developed to provide support to healthcare facilities (HCFs) and communities around each confirmed case, (3) IPC in HCFs: HCFs were assessed using a modified WHO SVD IPC scorecard rapid assessment tool that measured 15 IPC capacity domains, mentorship and IPC supplies were provided to HCFs with low scores on the rapid assessment.

RESULTS

A KMA task force was established, and 13 IPC Rings were activated; 790 HCFs were assessed for IPC readiness, and 2,235 healthcare workers (HCWs) were trained. The mean (± standard-deviation) IPC score was 59.2% (± 18.6%) at baseline and increased to 65.5% (± 14.7%) at follow-up after 2 weeks (p < 0.001) of support. The mean IPC scores at baseline were lowest for primary HCFs (57%) and private-for-profit HCFs (47.1%). Similar gaps were revealed across all HCFs, with eight out of 15 (53.3%) IPC capacity areas assessed, resulting in scores < 50% at baseline. At follow-up, only four out of 15 (26.7%) capacity areas (26.7%) were below this threshold.

CONCLUSION

The IPC strategy enhanced the IPC capacities at HCFs and could be adopted for future outbreaks. Leadership commitment and resource allocation to IPC during non-outbreak periods are critical for preparedness, rapid response, and access to safe care.
