mosquito-borne diseases

Somehow it’s taken us until the penultimate episode to cover this season’s first mosquito-borne virus. But we assure you, this episode is well-worth the wait. Although Chikungunya virus is often lumped in with dengue or Zika, the unique characteristics that distinguish Chikungunya virus from these other arboviruses are just as important to note as the similarities among them. In this episode, we explore these differences and similarities in the biology of Chikungunya virus before reassessing what we thought we knew about the history of this disease, a history that is presently under revision. Finally, we wrap up the episode as we always do, by taking stock of where we stand with Chikungunya virus today. Tune in for a good deal of dengue compare/contrast, a whodunnit (or whichdiseaseisit) in the history of these two diseases, and a frustrating attempt to gather present-day case numbers.

Our first vector-borne disease episode of season 3 and our first mosquito-borne pathogen in quite some time, dengue virus proves itself to be more than a worthy topic (and quite a formidable adversary in terms of public health). This week we are joined by Dr. Alex Trillo who drops some firsthand knowledge on the excruciating symptoms that give dengue its colloquial name “breakbone fever”, and then we trace the virus’s path from its evolutionary origins in ancient forests to the inevitable emergence of dengue hemorrhagic fever following modern war. We round it all out with some truly horrifying stats on the prevalence of dengue today as well as some promising research on reducing the prevalence of dengue tomorrow.

Zika virus may not have as long and storied a history as many diseases we've covered, but in a short time it has managed to make a big impression.

From the first discovery of the virus in a Ugandan jungle, to the heartbreaking effects only recently discovered, to the future of Zika research and vaccine development, we'll fill you in on everything you want to know and then some.
