The World Health Organization (WHO) has issued a stern warning that the next global pandemic is inevitable, urging nations to prioritise immediate preparation to prevent a repeat of recent catastrophes.
WHO Director-General Tedros Adhanom Ghebreyesus stated that the world must act now to strengthen health systems and response mechanisms. The warning follows reports on the massive economic and human toll caused by the COVID-19 pandemic, which left the global community vulnerable and unprepared.
According to Tedros, the previous pandemic resulted in well over 20 million excess deaths and caused a staggering loss of more than $10 trillion from the global economy. These figures serve as a grim reminder of the cost of delayed action and inadequate international cooperation.
Economic and human costs of global health crises
The scale of the economic disruption caused by the recent health crisis has fundamentally altered global markets. The $10 trillion wipeout mentioned by the WHO chief reflects not only the direct costs of healthcare and lockdowns but also the long-term impact on supply chains, labour markets, and international trade.
For African nations, including Nigeria, the consequences of such a crisis are particularly severe. During the COVID-19 pandemic, many countries on the continent faced significant challenges regarding vaccine equity and the high cost of medical supplies. This vulnerability highlighted the urgent need for the decentralisation of pharmaceutical manufacturing, particularly within Africa, to ensure that the continent is not left at the back of the queue during future outbreaks.
Health experts argue that the focus must shift from reactive crisis management to proactive prevention. This involves increasing investment in early warning systems, pathogen surveillance, and the strengthening of primary healthcare infrastructure. In Nigeria, where infectious diseases such as Lassa fever and yellow fever remain persistent threats, the ability to scale up response measures rapidly remains a critical priority for the Nigeria Centre for Disease Control (NCDC).
The WHO is currently facilitating negotiations for a global pandemic accord, an international treaty aimed at ensuring more equitable access to medical countermeasures and better sharing of biological data. However, the effectiveness of this treaty depends on the political will of member states to commit to sustained funding and resource sharing.
Despite the warnings, significant questions remain regarding how developing nations will fund the necessary upgrades to their health security frameworks. While international agencies call for increased readiness, the actual allocation of the billions of dollars required to build resilient health systems remains an unresolved issue among global leaders.
The WHO is expected to continue its push for the adoption of the pandemic treaty at upcoming international health assemblies, as nations struggle to balance domestic economic priorities with the necessity of global health security.
