    • Professor of Tropical Medicine and Clinical Research at Evandro Chagas National Institute of Infectology

    Patrícia Brasil, MD, PhD. I am a Professor of Tropical Medicine and Clinical Research at FIOCRUZ for graduate and post-graduate curricula and work as an Infectious Diseases (ID) Clinical Researcher/Attending Physician. My main area of research in the past 9 years has been acute febrile illnesses (AFI), with most studies centered in dengue and malaria until 2015.  Established in 2007, the AFI clinic is a sentinel service of emerging and re-emerging infectious diseases, as we utilize a flowchart of syndromic investigations, in collaboration with national reference laboratories for molecular diagnostics. The application of this protocol permitted us to identify the beginning of an epidemic of a new exanthematic disease, with Zika virus identified as the etiologic agent.  We have a large outpatient clinical service and to date have seen hundreds of cases of ZIKV infection in our patients.
