Course Description: This course is intended to provide a detailed description of the virology and pathogenesis of the Zika virus, including the modes of transmission, symptoms, and infection risks. The primary laboratory tests used for Zika virus identification are included. The CDC's Zika virus testing algorithms for symptomatic and asymptomatic individuals are reviewed, emphasizing the evaluation of women and newborns with peripartum Zika virus exposure. Finally, the prevention and treatment of Zika virus infections and the status of vaccine development is examined.
