Vector-borne diseases

WHO / Andy Craggs

Vector-borne diseases are illnesses caused by parasites, viruses and bacteria that are transmitted by vectors such as mosquitoes, ticks, flies snails. They occur in more than 100 countries worldwide, affecting as much as half of the world’s population.

Our work

At TDR, the research we support in this area currently covers arboviral diseases, malaria, human African trypanosomiasis (HAT), Chagas disease, leishmaniasis and snail-borne diseases such as fascioliasis and schistosomiasis.

Our work supports a wide spectrum of research from basic research on genomics and genetic modification of vectors to implementation research for the delivery and scale-up of control efforts and includes engagement across multiple communities and stakeholders.

The long-term aim of our work is to not only prevent vector-borne disease outbreaks but also to develop and implement strategies that reduce vulnerability and increase the resilience of populations at risk.
