Contact tracing tool supports supplies during pandemic

Digital, open-source system targets the haulage sector as a key source of Covid-19 infection spread.

A digital contact tracing tool has been developed to help counteract supply chain delays linked to Covid-19 in East Africa.

A multidisciplinary team led by the Roslin Institute with colleagues in Uganda consulted with key stakeholders to devise the open-source tool tailored to haulage use in developing countries.

A pilot study of the new digital contact tracing (DCT) protocol is to test its utility among truck drivers.

The team’s intervention follows severe delays at Uganda’s ports following the introduction of mandatory Covid tests for drivers, after a majority of cases at the peak of the country’s first Covid-19 wave were linked to the sector.

Although new testing requirements have been implemented to reduce these delays, the situation highlighted the need to develop swift and more effective methods.

Efficient tracing tool

The newly devised protocol uses mobile phone technology to integrate data on the road network infrastructure, time-stamped geopositioning, and Covid-19 test result data for drivers, to increase the speed and accuracy of public health contact tracing in the region.

The study will allow the research team to develop informative models that map the risk of Covid-19 disease and transmission, and to estimate the contribution of haulage to Covid-19 epidemiology in Uganda.

It will also collect feedback from truck drivers and other key participants, to review potential benefits and limitations of DCT technology. 

This is the first study that fully documents the development of a DCT tool in consultation with stakeholders on the African continent.

Although the tool was developed specifically in response to the threat from the Covid-19 pandemic, this study will also inform the safe deployment of DCT technologies needed for combating future pandemics in low-income countries.

The research, funded by the Medical Research Council, is published in BMJ Open and involved researchers at the University of Edinburgh’s School of Informatics.

Digital contact tracing (DCT) can be an effective way of supporting public health and societies at a time when supply chains are critically important. Here we use technology embedded within mobile phones to deliver an anonymised, ethical and legal approach to implementing DCT tailored for haulage to control infectious diseases, including but not limited to Covid-19 in the Global South."
