Ghana enhances infectious-disease forecasts using digital-surveillance tools

 


A study in Global Health Research and Policy by Struckmann, Findeiss, El-Duah, and colleagues proposes an enhanced framework for infectious disease forecasting in Ghana. This is crucial because Ghana, like many low- and middle-income countries, faces significant disease control hurdles due to limited infrastructure, inconsistent surveillance, and environmental variability.


The research highlights a key limitation: forecasting models from high-income countries often fail in these settings by ignoring local realities and data scarcity. To overcome this, the new approach integrates a hybrid dataset, combining local health statistics, meteorological inputs (rainfall, temperature, humidity), and community-based reports. This strategy is vital for compensating for underreporting and missing data, providing a more accurate view of disease transmission, particularly for vector-borne diseases like malaria and dengue.


Technologically, the team uses advanced statistical and machine learning tools, including Bayesian methods, to effectively process noisy and incomplete data. These methods enable the detection of complex relationships missed by traditional models and allow for real-time forecast updates. A major emphasis is placed on transparent uncertainty reporting, which empowers policymakers to make confident, informed decisions.


Beyond the technical aspects, the study champions community engagement in data collection and communication to build trust and local capacity. Furthermore, the framework links disease prediction with long-term climate change and urbanization trends, ensuring its future relevance and adaptability. Ultimately, this context-sensitive research, which merges data science, public health, and environmental insights, serves as a robust model for improving global outbreak preparedness, not just in Ghana, but across other similar nations.

Ghana's "Lightwave" system creates paperless hospitals, reducing wait times and digitizing patient records

Image
Ghana is undergoing a massive healthcare transformation with the rollout of the "Lightwave" Health Information Management System (LHIMS). This digital platform is replacing the chaotic, paper-based folders of the past with a streamlined, fully electronic system. In participating hospitals, patient records are now digital, meaning doctors can access a patient's full medical history instantly with a few clicks. This eliminates the frustration of lost folders and significantly speeds up the consultation process. The impact on efficiency has been dramatic. Patients no longer spend hours waiting for physical files to be retrieved, reducing overall wait times in outpatient departments. Beyond convenience, the system improves patient safety by ensuring that critical information, like allergies and past prescriptions, is always available to the treating physician. This shift towards paperless hospitals marks a major step forward for Ghana’s public health infrastructure, making ca...

Africa Health Insights: 20th November - 26th November' 2025

  Kenya launches mobile clinic network to bring care to remote communities Kenya is expanding healthcare access through a nationwide Mobile Clinic network. This initiative is designed to deliver essential medical services directly to remote, displaced, or marginalized communities that lack permanent infrastructure. By establishing temporary service points, the mobile clinics are crucial for bridging geographical barriers and ensuring continuity of care, especially in regions with poor road networks or humanitarian crises. The program emphasizes quality of care and data-driven operations. Health partners utilize a shared Mobile Clinic Quality of Care Toolkit, built on 24 evidence-based markers, to standardize and monitor service quality. The integration of advanced mHealth platforms, such as the M-Pesa payment system and remote monitoring, ensures that care is both accessible and equitable.

NGO urges sustainable emergency-operation centres in Nigeria’s PHCs

Image
The non-profit organization eHealth Africa (eHA) is strongly advocating for the long-term sustainability and local ownership of Public Health Emergency Operation Centers (PHEOCs) and associated digital infrastructure in Nigeria's Primary Health Care Centers (PHCs). While many PHEOCs were established with donor funding, particularly during the polio and COVID-19 responses, only a fraction remain fully functional due to issues like reliance on donor funding and maintenance failures. The NGO emphasizes that PHEOCs should be integrated as permanent public health command structures within PHC facilities, rather than viewed as temporary, donor-driven projects. Key to this sustainability is the adoption of renewable energy (solarization) to power critical ICT systems and the integration of climate-resilient digital solutions . eHA's own initiatives show the massive impact of solarization, leading to a surge in patients accessing PHCs and enabling 24/7 services like night deliverie...
