Zika fever is a mosquito-borne viral illness caused by caused by
Zika virus (ZIKV). The clinical course of Zika fever is similar to that
of Dengue fever, which is characterized by fever, joint pain, myalgia,
headache and rash. The cross reactivity with the antibody against
other flavivirus may lead to misdiagnosis, and detection of ZIKV in
blood or urine using polymerase chain reaction (PCR) is highly specific.
We report an imported Zika fever case from Thailand to
Japan, diagnosed by detection of ZIKV in urine using PCR.
