Read this text before watching the video above.

Climate change is expected to alter and expand the distribution of certain vector-borne diseases. Diseases such as malaria, dengue fever, tick-borne encephalitis, hemorrhagic fever with renal syndrome (HFRS), Lyme disease and Japanese encephalitis – are considered ‘climate-sensitive’ because changing temperatures and rainfall patterns can create new suitable habitats for the insects which spread them. In the case of malaria, control interventions and socioeconomic development appear to have played a more important role than climate change thus far, but this could change in future. For example, dengue has become closely associated with climate change over the past five decades, having increased 30-fold in this period.
