【 摘 要 】

"Zika virus" (ZIKV) is an enveloped, icosahedral virus and has a positive-sense, single-stranded RNA genome approximately 11 kb in length. Genetic studies have revealed three ZIKV lineages: East African, West African, and Asian. Serologic studies and virus isolations have demonstrated that the virus has a wide geographic distribution, spanning East and West Africa, the Americas, Indian subcontinent, and Southeast Asia. ZIKV can cause complications such as Guillain-Barré syndrome, meningitis, meningoencephalitis, and myelitis. During pregnancy ZIKV infection can lead to miscarriages and microcephaly, cerebral calcifications, macular neuroretinal atrophy, and loss of foveal reflex in the fetus. A clinically suspected case of infection with dengue negative result should be further tested for Flavivirus, including Zika. Immunofluorescence or enzyme-linked immunosorbent assay is used to detect specific IgM or IgG antibodies against ZIKV. In cases of positive ZIKV infection, symptomatic treatment should be given after excluding other condition such as dengue, malaria, and bacterial infections.
