“…The compatibility of USSD with both smartphones and non-smartphones also promotes digital inclusion, and could limit accessibility issues often associated with new healthcare technologies [30]. As a result of these potential benefits, a small number of digital health interventions currently deployed in LMICs are using USSD [31][32][33], including a recent USSD-based intervention developed to track COVID-19 symptoms in Ghana [34]. As the identified interventions primarily focus on infectious disease tracking and maternal-fetal medicine, there is a need for further research into the applicability of USSD to digital health interventions for chronic disease management.…”

Background Cardiovascular disease (CVD) is the number-one cause of death globally [1], with over three-quarters of deaths associated with CVD occurring in low-and middle-income countries (LMICs) [2]. In Uganda, CVD accounts for 10% of all deaths, making it the most common noncommunicable cause of death in the country [3]. The burden of CVD in Uganda also appears to be increasing, with the number of deaths attributed to ischemic heart disease increasing by 13.4% between 2007 and 2017 [4]. The rising burden of CVD in LMICs has led to an increased prevalence of heart failure (HF) [5, 6]-a common end result of CVD where the heart is unable to meet bodily demands for blood and oxygen [7]. Although there is currently no cure for HF, proper lifestyle changes, symptom management, and medical therapy can allow individuals

“…Swanson et al [8] gives details on the performance of contact tracing in Liberia during the 2014 to 2015 epidemic. Other uses of mobile phones in contact tracing have been used in tracing the spread of Tuberculosis (TB) [9]. Furthermore, the outbreak of COVID-19 and subsequent declaration as pandemic has seen a proliferation of mobile applications aimed at contact tracing to help combat COVID-19 [10] [11].…”

The COVID-19 pandemic has remained a global health crisis following the declaration by the World Health Organization. As a result, a number of mechanisms to contain the pandemic have been devised. Popular among these are contact tracing to identify contacts and carry out tests on them in order to minimize the spread of the coronavirus. However, manual contact tracing is tedious and time consuming. Therefore, contact tracing based on mobile applications have been proposed in literature. In this paper, a cross platform contact tracing mobile application that uses deep neural networks to determine contacts in proximity is presented. The application uses Bluetooth Low Energy technologies to detect closeness to a Covid-19 positive case. The deep learning model has been evaluated against analytic models and machine learning models. The proposed deep learning model performed better than analytic and traditional machine learning models during testing.

“…Its operations are simple, do not require access to the Internet access or the user's SIM card and it can be used on basic mobile phones, feature phones, and on smartphones. Most MNOs agree that USSD may be the best available option for SSA's low-income customers because of the security, user experience, compatibility with handsets, real-time interactivity, cost, and ease of deployment (Mosweunyane et al, 2014). The World Bank projected that Africa will house 90% of the world's very poor by 2030 if the current trend of rising extreme poverty continues (Wadhwa, 2018).…”

E-Money Security Dilemma: Advanced Cybersecurity Mechanisms and Legacy Mobile Payments in Sub-Saharan Africa

Mobile Network Operators (MNO) infrastructures are expanding in many Sub-Saharan African (SSA) countries that are increasingly adopting mobile payment services. The adopted model is outdated and not compliant with today's more secure, dynamic, and application-driven environments. Unstructured Supplementary Services Data (USSD) legacy technology is widely deployed in SSA countries due to several factors including compatibility with handsets, user experience, cost, and ease of deployment for the MNOs. A survey reveals that USSD is used by approximately 65-75% of the population for mobile payments. The MNOs infrastructure was developed for connectivity, rather than security, making the e-money ecosystem prone to cyber-attacks. End-to-end encryption (E2EE) is one of the recommended cybersecurity solution mechanisms. This research shows that tokenization with identity based encryption techniques is a suitable model to secure financial transactions over USSD as it provides an end-to-end encrypted path when combined with Internet Protocol Security (IPSec) and Transport Layer Security (TLS) while lessening changes to the technology itself and the underlying network. This implementation introduces additional cost for maintenance and management, and therefore, the governments need to adopt market-friendly laws, regulations, and policies to develop employable skills and facilitate MNOs' return on investment.
