Country	Health structure level	All health-related surveillance	IDSR	IDSR as % of all health-related surveillance
Burkina Faso¶
	Region	137,566 (18,231)	35,899 (4,746)	26.1 (5.51)
	District	51,296 (4,388)	10,790 (1,714)	21.0 (2.40)
	Primary	5,196 (965)	1,240 (161)	23.9 (2.92)
Mali
	Region	111,584 (23,116)	39,573 (8,977)	35.5 (2.62)
	District	51,354 (27,864)	13,941 (5,892)	27.1 (2.91)
	Primary health care center	5,851 (1,699)	1,181 (780)	20.2 (7.90)
Eritrea
	Province	205,333 (29,914)	69,920 (24,386)	34.1 (9.4)
	District	28,220 (4 411)	11,985 (2547)	42.5 (2.8)

*All costs were converted to 2002 US dollar equivalent. Values in parenthesis are standard deviation from the means (2002 – 2005) of 4 health regions, 14 districts and 20 primary health care centers in Burkina Faso, 3 regions, 3 districts and 3 primary health care centers in Mali, and 1 province and 1 district in Eritrea.

† All health-related surveillance involves all communicable and non-communicable diseases and health risk factors, including the IDSR targeted diseases and conditions listed in Additional file 1, appendix 1.

¶In Burkina Faso, total costs included costs extrapolated from the average per capita costs of laboratory and treatment costs for Eritrea and Mali (see Table 2). Without the laboratory and treatment costs, the mean annual all disease surveillance and IDSR program costs were 54,327 and 18,476, 31,147 and 6,594, and 4,316 and 1,056 per region, district, and primary health care center level, respectively.
