Zika Virus — What Clinicians Need to Know
Zika virus is a mosquito-borne flavivirus transmitted primarily by Aedes aegypti mosquitoes and an estimated 80% of persons infected with Zika virus are asymptomatic. Symptomatic disease is generally mild, with symptoms of fever, maculopapular rash, arthralgia, or nonpurulent conjunctivitis that typically last from several days to one week. Sporadic cases and outbreaks of Zika virus disease have occurred in countries in Africa and Southeast Asia. In 2015, the first local Zika virus transmission in the Americas was reported in Brazil and local transmission has now been in several countries or territories in the Americas. In the current outbreak in Brazil, a marked increase in the number of infants born with microcephaly has been reported and Zika virus infections have been confirmed in some infants with microcephaly. However, it is not known how many of the microcephaly cases are associated with Zika virus infection. Travelers to areas with ongoing outbreaks are at risk of becoming infected and spreading the virus to new areas, including the continental United States. During this Clinician Outreach and Communication Activity (COCA) Call, participants will learn about the epidemiology and clinical manifestation of Zika virus disease and how early recognition and reporting of suspected cases can mitigate the risk of local transmission.
