Vector-borne Diseases

Baroness Manzoor Excerpts

Thursday 14th December 2023 Lords Chamber

[Lord Evans of Rainow (Con)]

My Lords, I note that Health Ministers get asked Foreign Office questions, and Foreign Office Ministers get health questions. However, the right reverend Prelate raises a very good point. It is a very topical issue. The UK is a world leader in life sciences, and British science is at the cutting edge of fighting malaria. Our support to public/private product development partnerships has helped saved many lives. This includes support to the Liverpool-based Innovative Vector Control Consortium to develop novel bed nets and next-generation insecticides to overcome the threat of insecticide resistance. Since 2017, we have provided £44 million to develop new insecticides to prevent vector transmission of malaria and other vector-borne diseases. IVCC has developed many ground-breaking technologies, including a novel type of bed net that kills mosquitoes’ resistance to traditional insecticides.

[Baroness Manzoor (Con)]

My Lords, which vector-borne diseases are prevalent in the UK, and what are the Government doing to address this risk to public health?

[Lord Evans of Rainow (Con)]

My noble friend raises a very good point. Many of your Lordships will know that the primary vector-borne disease in the UK is currently Lyme disease. However, with climate change, we are likely to see conditions suitable for the establishment of invasive mosquitoes that are currently becoming established in other parts of Europe. These mosquitoes, as well as other species likely to be impacted by flooding, may increase the incidence of mosquito biting. In a warming climate, vector-borne diseases such as dengue and West Nile virus, which currently occur in warmer parts of Europe, will become more likely in the UK. We need to stay vigilant as these diseases may or may not occur in the UK.
