mSpray training begins in South Africa

Following the development of mSpray, a malaria control mobile application for tracking indoor residual spraying of pesticides, initial usability testing at Berkeley and in South Africa has been completed, we’ve iterated on the design of the app, and workers in South Africa are now being trained to use mSpray.

Below is a map that tracks the progress of the teams testing of mSpray.

Release of mSpray Mobile App to Aid Malaria Elimination

mSpray is an Android application that tracks indoor residual spray programs for malaria control.

It keeps accurate accounting of:

  • GPS coordinate of the spray
  • Quantity of DDT and pyrethroid sprays
  • Refilling of spray cans

All data are stored on the phones, as well as being transferred over the Internet to a secure server, where the data can be analyzed in real time as sprays occur in the field.  The GPS coordinates enable mapping of spray programs.  And, the time stamps of the spray events allow for monitoring of the frequency of spraying in different households.






The software can be downloaded here.
Latest versionmSpray v1.51 distribution

Old versions: mSpray v1.1 distribution and Documentation.
mSpray v1.0 distribution.

To use the software:
  • Install the .apk file onto the Android phone (Android OS version 2.2 or higher is required).
  • Copy the mSprayForm folder to the SD card of the phone.
  • Cellphones must be activated and have data plans.
  • In the phone’s settings, GPS must be enabled.
  • Data are saved on the SD card in the mSpray folder.
Programmers: Edmund Seto, Crystal Dou, and Daniel Wu (2012).
Funding for mSpray is provided by NIH grant 1R01 ES020360.  The PI is Brenda Eskenazi.

mSpray app to combat malaria, facilitate pesticide exposure research in South Africa

A new project: I’m working with Dr. Brenda Eskenazi, the recent John Goldsmith Award Winner for Outstanding Contributions to Environmental Epidemiology from the International Society of Environmental Epidemiology (ISEE) to develop mSpray — a new smartphone app that will be used in South Africa to track indoor residual spraying done for malaria control. While insecticide spraying is an effective tool to combat malaria transmission, household residents exposed to the pesticides (DDT and/or pyrethroids) may suffer from adverse health effects. Brenda is currently conducting a birth cohort study in Limpopo, South Africa to assess these effects.

I am co-designing the mSpray application with input from the local malaria control authorities. The application will be open source and available for developers in Africa and internationally to continue development.

Latest news: we have just received word that Zinto Marketing (a subsidiary of the Zinto Activation Group in South Africa will sponsor cell phones for the project.
