Prof. Ernest Kenu Warns Weak Health Systems, Not Borders, Fuel "Disease Smuggling" in Ghana

Professor Ernest Kenu, a distinguished Medical Epidemiologist at the University of Ghana, has identified weak public health systems as the primary catalyst for infectious disease outbreaks, rather than the cross-border movement of people. In a recent lecture titled "Disease Smuggling: The Unseen Cargo in Global Health Security," Prof. Kenu argued that the national focus should shift from border controls to strengthening domestic infrastructure. He emphasized that pathogens effectively "smuggle" themselves into communities where sanitation and hygiene protocols are compromised, making national health security a matter of internal preparedness rather than geographic isolation.

Drawing on lessons from Ghana's history with cholera outbreaks and the global COVID-19 pandemic, Prof. Kenu highlighted systemic failures such as poor sanitation, contaminated water supplies, and inadequate infection prevention practices as the true vulnerabilities. He noted that while international travel is often blamed for the spread of viruses, it is the underlying environmental and healthcare weaknesses that allow these diseases to take root and spread rapidly. Specifically, he pointed to the unnoticed movement of pathogens facilitated by unregulated food vendors and insufficient water safety standards as key drivers of local transmission.

To combat these threats, the epidemiologist advocated for a significant increase in investment toward Water, Sanitation, and Hygiene (WASH) infrastructure and the integration of modern technology into public health surveillance. He suggested that data-driven disease prediction and enhanced surveillance systems are essential for anticipating future outbreaks before they reach a crisis point. By improving detection capabilities and maintaining rigorous hygiene standards, Prof. Kenu believes the country can transition from a reactive posture to a proactive one, effectively closing the systemic gaps that pathogens currently exploit.

Prof. Kenu concluded by urging for greater public participation in disease surveillance, encouraging citizens to report unusual illnesses and support community-led prevention measures. He warned that new threats, including antimicrobial-resistant organisms and climate-sensitive pathogens, may already be emerging in the shadows of the current system. Enhancing Ghana's public health infrastructure is presented not just as a policy recommendation, but as a critical necessity to safeguard the nation against the next inevitable global health challenge.
