Micro 52: Togaviruses and Flaviviruses
This episode explores two important families of enveloped positive-sense RNA viruses frequently transmitted by arthropod vectors. Drawing from Murray’s Chapter 52, it examines how ecological cycles shape viral epidemiology.
The togaviruses include rubella virus and various alphaviruses. Rubella produces mild disease in children but poses serious risk during pregnancy, leading to congenital rubella syndrome. Alphaviruses often cause febrile illness with arthralgia.
The flaviviruses include:
* Dengue virus
* Zika virus
* Yellow fever virus
* West Nile virus
