Future Pandemics – What’s Next? Predicting The Frequency and Scale of Future Pandemics (Center for Global Development)

Center for Global Development writes: Amid a pandemic, it is difficult to consider preparing for the next one, especially when there is no certainty about its timing. COVID-19 is broadly viewed as being a “once in a lifetime” or “once in a century” pandemic; unfortunately, that is not accurate. But what is the actual return time to a future pandemic threat, and how can we ensure that the world is prepared next time? A team from Metabiota estimates that the next pandemic might not be as far away as we think. Historical modeling suggests that the frequency and severity of epidemics caused by wildlife zoonoses are increasing, driven by human activities and their impact on the environment. They estimate that the probability of a future zoonotic spillover event resulting in a pandemic of COVID-19 magnitude or larger is between 2.5-3.3% annually. In other words, there is a 22-28% chance that another outbreak on the magnitude of COVID-19 will occur within the next 10 years, and a 47-57% chance that it will occur within the next 25 years. Other groups like African Risk Capacity are examining these probabilities with an eye to assuring a more rapid response when outbreaks occur.
