Fig. 6
Case notification dates against week in which the case was diagnosed through the paper and MalariaConnect systems (confirmed and all MalariaConnect cases) compared against the World Health Organization and National Department of Health action threshold (mean + 2SD). The week of diagnosis is shown on the vertical axis and each mark on the graph indicates an epidemic week. The position of the mark on the horizontal axis indicates the date on which sufficient cases were notified for it to be identified centrally that threshold had been surpassed. Blue marks indicate when this occurred through the paper system, and red marks when it occurred through MalariaConnect. The red vertical dotted line represents where the MalariaConnect data surpassed the action threshold (26 April, week 17) while the blue line is for the paper system (5 May, week 18)
