Zika Virus Guidance for Providers

As you are aware, there is currently a Zika virus outbreak in Central and South America, Mexico, and the Caribbean. Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito. These are the same mosquitoes that spread Dengue and Chikungunya viruses. The Zika virus can be passed from a pregnant woman to a fetus during pregnancy. There are currently no locally transmitted cases in the continental United States but cases are being reported in returning travelers. The number of Zika cases among travelers returning to the United States will likely increase given the ongoing outbreaks.

The current Zika outbreak has been associated with an increase in congenital microcephaly in Brazil. The Centers for Disease Control and Prevention has issued a travel alert recommending that pregnant women consider postponing travel to any area where Zika virus transmission is ongoing. Pregnant women or women trying to become pregnant who do travel to one of these areas should strictly follow steps to avoid mosquito bites during the trip.

While most infections are asymptomatic, Zika virus infection should be considered in patients with acute onset of fever, maculopapular rash, arthralgia or conjunctivitis, who traveled to areas with ongoing transmission in the two weeks prior to illness onset. Medical care for patients with possible Zika virus infection requires only standard precautions.

Guidance on evaluation and testing for pregnant women and infants has been provided by the CDC . Testing requires coordination through the Michigan Department of Health and Human Services. There are no commercially available tests for Zika virus infection.
