Despite widespread circulation, most of Brazil remains susceptible to infection. CHIKV
vaccination has the potential to substantially reduce disease burden.

Northward expansion of Aedes albopictus-associated arbovirus transmission risk in Europe
Since 2007, outbreaks of chikungunya and dengue have become increasingly frequent

Rt measures how quickly a pathogen spreads and was central to understanding and controlling COVID-19. In our latest work, we extend this concept to vector-borne diseases, developing a new, renewal equation–based framework that links infection dynamics in humans and vectors.
