Data on the above indicator is collected using manual paper forms which are then submitted to the county for the entries to be made on excel spread-sheets there after discussed at the CHMT level. This double entry process makes the data prone to errors and inconsistency. When the county stakeholders use the extracted data they end up deducing inaccurate conclusions from the report collected on the county population. There is a need to build a minimum viable solution for the Community health workers involved in data collection. This will ensure accuracy when mapping data for children for immunization. Keep in mind that data collection areas are resource constrained and majority of the health officers involved are volunteers who may only be willing to incur as minimal cost as possible.
