Table 2. Quantitative comparison of attributes of SORMAS and the conventional surveillance system in response to monkeypox outbreak in Nigeria, November 2017–July 2019*.

Data availability for selected variables	SORMAS, %† n = 90	CS, %‡ n = 150	95% CI for difference
Sex	91	92	(−0.09 to 0.07)
Occupation	84	57	(0.15 to 0.39)
Date of birth	69	55	(0.00 to 0.27)
Onset date of symptoms	89	85	(−0.06 to 0.13)
Body temperature	53	3	(0.39 to 0.62)

*95% CI indicates difference in percentage of completeness determined by using 2-sample χ² test. CS, conventional system; SORMAS, Surveillance Outbreak Response Management and Analysis System.
†Percentage of completeness for monkeypox cases notified directly in SORMAS by district surveillance officers in the field. 
‡Percentage of completeness for monkeypox cases that arrived at the Nigeria Centre for Disease Control though the conventional system and were retrospectively registered in SORMAS.
