The COVID-19 Digital Risk Assessment and Mapping known as HealthCheck


In a collaborative effort, Wits RHI’s is collaborating with Praekelt and the NDOH to build a USSD and WhatsApp Digital Risk Assessment and Mapping Tool called “COVID-19 HealthCheck”. The NDOH WhatsApp platform that houses the HealthCheck tool, has become the most highly utilized platform for users in South Africa currently serving millions of South Africans.

Based on responses users will be classified as Low, Moderate, High or Critical risk and suggested actions will be given based on this classification. Once a user is on the system, weekly prompting messages will be sent to the user base, to encourage them to recheck their symptoms.

It will also create a wide-reaching channel for government to communicate directly with, and to educate, citizens as the pandemic evolves.
