As Prof. Christian Happi, Director of the African Centre of Excellence for Genomics of Infectious Diseases (ACEGID), pointedly remarked in a recent <em>France 24<\/em> perspective, &#8220;It&#8217;s<strong> not if there will be another pandemic, but when.&#8221;<\/strong> In an interconnected world where pathogens do not carry passports, the interval between the first spillover and a global crisis is shrinking. To protect the world&#8217;s health, we must shift from a reactive posture to a proactive one. This shift is powered by one essential tool: <strong>real-time genomic surveillance.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>From Delayed Responses to Real-Time Action<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For decades, the narrative of disease surveillance in Africa was defined by external dependence. During the GESDA fireside chat, Prof. Happi recalled a sombre reality from the 2014 Ebola outbreak: samples were often flown out of the continent for analysis, with results arriving <strong>&#8220;two years after&#8221;<\/strong> an outbreak that had already <strong>&#8220;killed almost everybody&#8221;.<\/strong><br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That delay was a death sentence. Today, the script has been flipped. By leveraging genomic tools on the ground, teams can now pinpoint exactly how a virus enters a population, track mutations in real-time, and develop rapid diagnostic tests within days. This transition from &#8220;outsourced science&#8221; to &#8220;local leadership&#8221; has proven to be the life-saving difference in containing threats before they cross borders.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"337\" src=\"https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-1024x337.jpeg\" alt=\"\" class=\"wp-image-1699\" srcset=\"https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-1024x337.jpeg 1024w, https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-300x99.jpeg 300w, https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-768x253.jpeg 768w, https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-1536x506.jpeg 1536w, https:\/\/ighresearch.org\/en\/wp-content\/uploads\/2026\/03\/image-2048x675.jpeg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Sentinel Model: Speed, Accuracy, and Trust<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the heart of this defence is the <strong>Sentinel project<\/strong>, a collaboration between the IGH and the Broad Institute. As Prof. Happi explained during a Global Health Hub conversation, Sentinel is built on three pillars: <strong>real-time genomic surveillance, open data sharing, and translational research.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The results speak for themselves:<br><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>SARS-CoV-2:<\/strong> African scientists sequenced the virus within 48 hours of the first confirmed case on the continent.<\/li>\n\n\n\n<li><strong>Ebola:<\/strong> Rapid containment in Lagos prevented a potential urban catastrophe.<\/li>\n\n\n\n<li><strong>Marburg &amp; Mpox:<\/strong> Swift genomic identification supported targeted interventions in Rwanda and beyond.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, a tension remains. While the technology is proven, the scale is not yet universal. The challenge lies in moving from successful &#8220;pockets of excellence&#8221; to a continent-wide infrastructure that can withstand the next Big One.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Surveillance as Sovereignty<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The push for genomics is about more than just biology; it is about equity and ownership. When the MacArthur Foundation announced its support for Sentinel, Prof. Happi noted, <strong>&#8220;This investment affirms that solutions to global health challenges can be led from Africa.&#8221;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By training over 3,000 health workers across 53 African countries, the mission transcends technical data. It is about building a <strong>&#8220;trusted research environment&#8221;<\/strong> where African scientists lead the narrative. Given that Africa holds approximately <strong>70% of pathogens with pandemic potential<\/strong>, the continent\u2019s ability to monitor its own landscape is a matter of global security.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A Call to Global Vigilance<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As funding for global health faces potential cuts, the &#8220;many hands&#8221; required to manage emerging diseases are falling away. We cannot afford to let our guard down.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The vision of the Institute of Genomics and Global Health is clear: we must invest in scaling real-time surveillance and African-led capacity today to avoid the astronomical costs of a pandemic tomorrow. Protecting the world\u2019s health is a collective responsibility, but the frontline begins with the data, the speed, and the leadership emerging from Africa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Insights from Prof. Christian Happi and the Institute of Genomics and Global Health The question hanging over global health security is no longer a matter of &#8220;if&#8221; but &#8220;when&#8221;.
