Hope as three Kenyans develop app for contact tracing

Share

Kenyans ingenuity at innovations that help prevent loss of lives and the spread of corona virus has signaled hope that global problems can be solved by local solutions.

From hand sanitizers to ventilators and personal protective equipment (PPEs), local innovators and manufacturers are working hard behind the scenes to beat the pandemic that by yesterday had claimed close to half a million lives across the globe according to the World Health Organization (WHO).

Three local researchers — biochemist Donatus Njoroge, IT expert Gideon Kamau, and medical doctor Jesse Gitaki —  have developed a Covid-19 tracing system dubbed ‘KoviTrace’ that provides access to all the persons that a patient came into contact with in the last 14 days.

The technology has a back end system (a web-controlled portal for use by the administrator (Ministry of Health) and a front end system (an application that can be installed on Android phones or accessed via a USSD code by those without smart phones).

It also provides users with an updated access to WHO’s frequently asked questions about the disease and a self-screening test that gauges the user’s vulnerability to the disease based on his or her previous interactions, behavior and movements.

The technology can be used by the Ministry of Health in tracing all persons that Covid-19 patients came into contact with, and by Kenyans in establishing if they have been in contact with persons who tested positive.

“Once an individual has tested positive, a Ministry of Health official will only be required to key in his phone number onto the web portal and command it to trace all his contacts within the last 14 days instead of relying on his word of mouth,” explained Mr Njoroge, the researcher behind the idea.

The system also sends an alert to all the persons that the patient came into contact with. The alert, received in the form of a text message, also contains information on preventive measures, contacts of the nearest hospital and the emergency toll-free numbers of the respective county Covid-19 coordinator.

“This system works for those who have installed the app in their phones or registered with the USSD code,” added Mr Njoroge, who is also the head of innovations, intellectual property and community engagements at Mt Kenya University. He said the system can trace every person that the individual has been in contact with virtually, thus minimizing the risk of persons going into hiding.

“It uses a Geo-sensing technology that tracks the user’s location and time. The data is saved under a unique ID that is encrypted and cannot be accessed by other parties,” Mr Njoroge adds.

With over seven million confirmed infections as per yesterday morning, countries strategising on how to open up their local economies have one major nagging headache — the growing threat of increased local transmissions.

In his much-awaited June 6 speech, President Kenyatta warned that countries that opened up their economies without laying down proper protocols experienced a surge in the number of infections.

The government is conducting contract tracing with the help of NIS through accessing patients’ phone data to trace their last movements, a procedure that is not feasible at large scale, besides being expensive.

If ‘KoviTrace’ is approved and adopted for use by the government, Kenya will rank among global economies that have established similar apps for use in taming the virus before reopening the economies.

One such country is Australia, which developed COVIDSafe, an App that is tracing contacts of patients within the last 21 days.
