In this second episode, Professor of Disease Ecology, Henrik Salje of Cambridge University's Department of Genetics, shares important insights into vector-borne infectious diseases spread by mosquitoes, ticks and other insects. No longer confined to tropical climates, he shares with us the reasons for their increasing emergence and spread in Europe. How can we prepare as a society? What can we do as individual citizens? And, importantly, what work is the EU and its member states already undertaking in the areas of prevention, surveillance and treatment.
