What can we do to combat the next pandemic?

James, a veterinary epidemiologist who leads the Disease Dynamics Unit in Cambridge, has spent much of the last 15 years working on potentially zoonotic viruses in African bats and focuses his research on infectious disease emergence and control, publishing widely on the risks of disease from wildlife.

Back in March 2020, James was scheduled to give a lecture as part of the ���ӽ紫ýExplores Borders series, entitled ‘Diseases without Borders: Emerging infectious diseases in Africa’, when the UK suddenly went into lockdown number one. 

More than a year later, as we emerge from a third national lockdown, James will finally deliver his ���ӽ紫ýExplores Borders lecture, albeit online and with a shifted perspective in the light of the pandemic: ‘Diseases without Borders: what can we do to combat the next pandemic?’

Ahead of the talk, we spoke to James, who is also a ���ӽ紫ýFellow, to ask him some pandemic-focused questions and to find out what lies ahead.   

What has really stood out to you since the onset of this pandemic? Has anything surprised you? 

The stand-out for me has been the massive variation in the impact, so far, between different countries and within different countries. Within country, variation has been driven in many cases by inequalities, usually wealth-related, but often along ethnic divisions. The vulnerability of some groups has been stark. We still do not understand why, how and when some countries have been hit when they have been. 

Where are we now in the lifecycle of this pandemic? Are you optimistic that the vaccines will deliver global normalcy within the next, say, twelve months, or do you think we'll see more variants hit countries hard and stretch out the grip of the pandemic?  

While the UK appears to be in a good situation, the contrast in many other countries such as Brazil, India and even Sweden is not good. This is a global pandemic and we need to focus more on international controls. 

It’s been suggested that a strategy in dealing with possible future pandemics is to look, not at animals first, but at people who come into contact with animals most frequently, in an effort to identify spill-over viruses in humans as they happen and before they have chance to fully adapt to humans. What’s your take on that?

We have been talking for some years, based on our research, about the need to invest in primary human healthcare in hotspots for disease emergence. On Friday, I’ll be talking about how bad we are at diagnosing Ebola spillover cases in sub-Saharan Africa, where around 90% of them are never found – despite this being one of the most feared of human diseases. We must do more in this respect to protect global health.

Is great change needed in the way we interact with nature to prevent further pandemics? Is this about banning live wildlife markets, or is it about stopping forest loss, land conversion and human encroachment?

Global biodiversity loss is an important driver of zoonotic spillover – and some of the ways that agriculture works is an important driver of this. But humans are an important part of biodiversity and it is vital that we do not penalise indigenous peoples around the world in our desire to protect biodiversity – they are the solution to, not the cause, of biodiversity loss. Banning international trade in live animals is one logical solution to reducing risk that we should fully support. 

Are you optimistic that we're learning the lessons of this pandemic?    

I am very pessimistic about learning global lessons well enough to see real changes being sustained into the future. This is why we must continue to argue and fight for systematic change. We will have pandemics in the future as we have in the past, but we can do much more to prevent and mitigate them.

‘Diseases without Borders: what can we do to combat the next pandemic?’ takes place online on Friday 7 May 2021 at 18:00. You can .

The lecture is part of the Science Society and  series.
