[Perspectives] Aedes aegypti suppression in the Americas: historical perspectives

Today populations in the Americas are under increasing threat from the dengue, chikungunya, and Zika viruses, spread by the Aedes aegypti mosquito. In earlier centuries, the same mosquito spread the deadly haemorrhagic viral infection known as yellow fever. Rigorously organised vector control programmes in the 20th century, however, ended the urban cycle of yellow fever in the Americas. This historic public health success has relevance for the current public health crisis.
