Global warming could also create conditions favourable for a return of malaria to the UK, where it was once endemic in Kent, although the disease was very unlikely to gain a foothold, said Prof Paul Hunter of the University of East Anglia in Norwich.
Prof Hunter, who will talk today at a Society for Applied Microbiology meeting at the Royal Society in London, said it was accepted that climate change would most likely mean hotter summers and more frequent and heavy rainfall and storms.
Between one and two per cent of the UK population rely on private water supplies, he said, and they would be most at risk of a resurgence of water-borne infection. Inadequate storage of food or a rise in the number of people mounting barbecues in warmer weather could increase the risks of food poisoning.
