Assessing the external validity of mobile phone surveys for monitoring ITN coverage indicators: a comparison with household surveys in Tanzania

Publication Date: December 2025
Country: Tanzania

Insecticide-treated net (ITN) coverage indicators allow country malaria programmes to understand the overall coverage of their ITN distribution activities and can be used to forecast the need for additional ITN procurement and to plan future distribution campaigns. As a result, more frequent data collection could better guide programme strategies, particularly for those strategies operating on an annual framework; however, the high costs and infrequency of national-scale, household surveys limit their practicality for ongoing monitoring. Due to the rapid growth trend of mobile phone ownership in low- and middle-income countries in recent years, mobile phone-based surveys (MPS) have emerged as a comparatively inexpensive alternative to large-scale household surveys.
