Biosecurity and Infectious Diseases

Baroness Hayman Excerpts

Thursday 18th January 2024 Lords Chamber

[Baroness Hayman (CB)]

My Lords, it is a pleasure to follow the noble Baroness and to speak in this debate. I declare my interest as chair of Peers for the Planet and should perhaps declare an interest as a vice-chair of the All-Party Group on Malaria and Neglected Tropical Diseases. I share that honour with the noble Lord, Lord Trees, who introduced this debate so effectively and comprehensively that none of us should go over six minutes in our contributions, because there is no need to repeat the devastating analysis he gave of the risks to the UK. I will focus on the risks that come in response to climate change, particularly of vector-borne diseases, which are so susceptible to changes, sometimes very small, in climate.

I remember talking to physicians in Texas many years ago about their concern at seeing locally transmitted cases of dengue. These had never been seen before in Houston but were growing in response to different climatic changes and, of course, population changes. The noble Lord, Lord Trees, said that no man is an island—that is the phrase we always use—but, these days, no island is an island either. We cannot protect ourselves totally by putting up barriers to the importation of these sorts of diseases. I believe that means that, while we are focusing today on the risks to the UK, we have to understand that the burden of many of these diseases and their increase is being felt not in the future for the UK but in the here and now in parts of Africa and Asia, where they are spreading.

That makes me ask the Minister—who, like everyone else, I welcome—to perhaps say something when he replies about the support we are giving in other countries, as part of a global responsibility for health and as self-protection for this country in not putting barriers up, as the noble Baroness, Lady Bennett, was saying, but taking away the threat of that disease importation and the threat caused by the other health effects of global warming and climate change that lead to instability, mass migration and refugee problems, of which we have a very Eurocentric view. There are huge refugee problems caused by the effects of climate change in areas other than the ones that we are talking about in this debate.

We should never forget the health effects of pollution. The burning of fossil fuels, leading to the pollution of the atmosphere, particularly in cities, is thought to cause 7 million premature deaths annually. The air quality in areas of cities, not just in Europe but in India in particular, can be catastrophic when they then have extreme heat events. We have to recognise that heat stress, pollution, flooding and drought—all those effects of climate change—have profound effects on health.

It was significant that last year’s COP 28 was the first COP with a whole day relating to the health effects of climate change and biodiversity loss. It brought forth a declaration, signed by 143 countries, agreeing that they needed to facilitate collaboration on human, animal, environment and climate health changes, such as by implementing a One Health approach addressing the environmental determinants of health, strengthening research on the linkages between environmental and climatic factors and antimicrobial resistance, and intensifying efforts for the early detection of zoonotic spillovers. I hope that the Minister can say what we as a country are doing to implement that declaration.
