Clinical Significance
This test is intended for the qualitative detection of Zika virus in serum from individuals who meet the Centers for Disease Control and Prevention (CDC) clinical and epidemiological criteria for Zika virus testing. Zika viruses are primarily transmitted by Aedes aegypti and Aedes albopictus mosquitos [1].
Most individuals with Zika infections are asymptomatic. Individuals with symptomatic infections may experience fever, rash, and muscle/joint pain [2].
Per the 2019 CDC guidelines, testing is recommended only for symptomatic pregnant women with a history of living in or traveling to a geographic area at risk for Zika. For current testing guidelines, see https://www.cdc.gov/zika/hc-providers/testing-guidance.html
For individuals meeting the CDC criteria, concurrent testing of serum and urine is recommended as soon as possible after symptom onset.
Zika infection shares clinical and epidemiological features with other arbovirus infections such as Dengue and Chikungunya. For CDC guidelines on testing concurrently for Zika and Dengue, see https://www.cdc.gov/dengue/healthcare-providers/testing/testing-guidance.html
