Imagine a world where a simple text message could save lives. That’s the bold vision behind a groundbreaking initiative by the Africa Centres for Disease Control and Prevention (Africa CDC), which is leveraging mobile messaging to tackle one of Africa’s deadliest diseases: tuberculosis (TB). But here’s where it gets controversial: can SMS, a technology often seen as outdated, truly revolutionize healthcare in an era dominated by apps like WhatsApp? Thanks to a $100,000 grant from the World Bank, Africa CDC is putting this idea to the test in Ethiopia and Liberia, two countries hit hard by TB.
The pilot project explores whether structured SMS reminders can improve treatment adherence among TB patients—a critical issue, as interrupted medication leads to higher relapse rates and the spread of drug-resistant strains. And this is the part most people miss: while traditional SMS usage is declining globally, embedding it into essential health services could reposition it as a high-reliability, value-added tool for telecom operators. For instance, Application-to-Person (A2P) messaging, which includes alerts like banking notifications, already generates significant revenue in Africa, with projections reaching $3.55 billion by 2034. By integrating SMS into healthcare, this initiative could create a win-win: improving health outcomes while securing a sustainable revenue stream for telecoms.
Dr. Mosoka Fallah, Acting Director of Science and Innovation at Africa CDC, emphasizes the project’s potential: ‘This research integrates digital innovation into TB care, offering patient-centered solutions to real-world challenges.’ Running from November 2024 to December 2025, the study involves partnerships with health ministries, universities, and local bureaus in both countries. If successful, it could shape national TB strategies and inspire broader digital health integration across Africa.
Here’s the bigger picture: TB remains a silent crisis, with 10.8 million cases globally in 2023 and over 1.25 million deaths. Ethiopia and Liberia, with incidence rates of 119 and 308 cases per 100,000 people respectively, are prime examples of why innovative solutions are urgently needed. SMS reminders, though seemingly simple, could bridge the adherence gap at scale—a game-changer for overburdened health systems.
But here’s the catch: as younger users flock to OTT platforms like WhatsApp, SMS risks becoming obsolete. By 2027, third-party apps are expected to surpass SMS in business messaging volume. This shift raises a thought-provoking question: Can SMS remain relevant in Africa’s digital future, or is it destined to be replaced by richer, app-based formats? Africa CDC’s project argues that by focusing on critical services like healthcare, SMS can carve out a niche as a premium, reliable channel.
If this model proves effective, its impact could extend beyond TB. Similar approaches could be applied to HIV, maternal health, immunizations, and chronic disease management, creating predictable, high-volume A2P traffic and revitalizing SMS in Africa’s digital ecosystem. Here’s where you come in: Do you think SMS can still play a central role in Africa’s healthcare, or is it time to fully embrace app-based solutions? Share your thoughts in the comments—let’s spark a conversation that could shape the future of digital health in Africa.
