The environment plays a powerful role in the transmission of infectious diseases, including vector-borne diseases such as malaria, dengue, and human African trypanosomiasis. It is therefore of huge significance to public health strategies around the world. Two particularly important aspects are socio-ecological systems and climate change.
Growing evidence suggests that climate change will have substantial impact on already vulnerable populations. For instance, changes such as increased rainfall can affect African drylands and so increase the burden of water-related vector-borne diseases in areas already susceptible to poverty.
Research to improve our understanding of environmental drivers of infectious disease can lead to improved vector control measures and disease prevention. Research also needs to explore how policies of health, environment and development can best be aligned – since many vector control and disease prevention measures require action by sectors such as water, agriculture and sanitation – areas outside of the traditional domain of health services.
