TS.B.5.6 Higher temperatures combined with land use/land cover change are making more areas suitable for the transmission of vector-borne diseases . More extreme weather events have contributed to vector-borne disease outbreaks in humans through direct effects on pathogens and vectors and indirect effects on human behaviour and emergency response destabilisation . Climate change and variability are facilitating the spread of chikungunya virus in North, Central and South America, Europe and Asia ; tick-borne encephalitis in Europe ; Rift Valley fever in Africa; West Nile fever in southeastern Europe, western Asia, the Canadian prairies and parts of the USA ; Lyme disease vectors in North America  and Europe ; malaria in eastern and southern Africa ; and dengue globally . For example, in Central and South America, the reproduction potential for the transmission of dengue increased between 17% and 80% for the period 1950-1954 to 2016-2021, depending on the sub-region, as a result of changes in temperature and precipitation .
