This post covers key insights for pandemic risk reduction from our Risk Analysis paper, which was awarded ‘Best Paper of 2025’

Global pandemics, such as the Black Death, the Spanish Flu, and most recently, COVID-19, have brought hardship and loss: from global famine to loss of life, from deepening inequality to overwhelming health systems, and more.

An important lesson arises: the more prepared we are against a pandemic, the better we can protect the lives of millions.

Historically, pandemics usually arose through animal-to-human interaction. In the present day, a new origin source for pandemic potential pathogens (PPP) has emerged from human interaction with PPP in laboratory settings (for example, in vaccine development). This represents a new type of risk with different characteristics (e.g., geographic distribution) and potential for harm.

Alongside laboratory origin sources, increased global travel (especially via air networks) facilitates the rapid spread of pathogens, further increasing potential for harm. Even if a particular country is unlikely to give rise to a new emerging infectious disease or be the source of a lab leak, it might be strongly connected to other countries that do face such risks.

But infectious diseases don’t affect only our physical and mental [...]
