Estimated number of SARS-CoV-2 infections in six districts of Zambia (March–July, 2020)^*

Estimated number of SARS-CoV-2 infections^†, n (95% CI)	14 218 (6854–21 581)	21 258 (13 325–29 191)	249 797 (70 404–429 192)	14 778 (264–29 293)	84 459 (52 560–116 359)	31 234 (8940–53 527)	454 708 (312 705–596 713)
Reported cases in official statistics, n	124	21	3521	692	450	109	4917
Ratio of reported cases to estimated infections	1:115	1:1012	1:71	1:21	1:188	1:287	1:92

Prevalence estimates for the combined measure were applied to individual district populations and the sum of the six districts populations; because each estimate was made independently, the sum of individual district totals does not equal the total for the six districts overall.

^†

Calculated by applying the prevalence estimate for the subset of participants who had both rtPCR and ELISA tests to the census population projection.
