Using Mobile Technology to Facilitate Reactive Case Detection of Malaria

Description

Zanzibar is comprised primarily of two large islands with a population of 1.3 million. Indoor Residual Spraying (IRS) campaigns, distribution of long-lasting insecticide treated bed nets (LLINs), and use of Rapid Diagnostic Tests (RDTs) have reduced Malaria prevalence from 39% in 2005 to less than 1% in 2011-2012. As malaria burden decreases, there is an increasing need to track and follow up individual cases to contain transmission that could lead to resurgence. One method being used to achieve these aims is reactive case detection (RACD). RACD is generally understood to be triggered whenever a case is identified by passive case detection. The response involves visiting the household of the newly reported case and screening family members. Depending on program protocol, it may also involve screening neighbors within a defined radius. RACD has been used or tested in Cambodia, China, India, Peru, Senegal, Swaziland, Tanzania, and Zambia. RACD can be resource intensive. Several studies raise questions concerning whether and how RACD can be prioritized and targeted effectively as case numbers continue to decline.

Objective

This presentation will share findings from more than three years of using mobile technology for reactive case detection (RACD) to help eliminate malaria in a well-defined geographic area. It will review the concepts of RACD, the application of mobile technology, lessons learned from more than three years of application, and considerations in applying this technology in other malaria elimination contexts.
