Current guidance for US laboratories testing for Zika virus infection (https://www.cdc.gov/zika/laboratories/lab-guidance.html) recommends that testing be limited to specimens collected from patients meeting CDC’s clinical and/or epidemiologic criteria for testing (http://www.cdc.gov/zika/symptoms/index.html; http://www.cdc.gov/zika/hc-providers).1 Clinical signs and symptoms associated with Zika virus infection are discussed here: http://www.cdc.gov/zika/symptoms. Current Zika information and guidance is available on CDC’s Zika website at http://www.cdc.gov/zika. Information specific to laboratories is available at http://www.cdc.gov/zika/laboratories. Current information and guidance specific to Zika virus in Puerto Rico can be found on the Puerto Rico Department of Health website: http://www.salud.gov.pr/Sobre-tu-Salud/Pages/Condiciones/Zika.aspx.
