Abstract ObjectiveTo investigate an imported case of Zika virus disease in Wenzhou City, to explore the source of infection,to analyse the problems during surveillance and diagnosis, and to provide evidence for prevention and control of Zika virus disease. MethodsBy field investigation, medical records of the patient were collected and a face-to-face interview was conducted; blood, urine and saliva samples within 48 h were collected for RNA detection; assess the risk of disease spreading by mosquito surveillance and take control measures. ResultsThe onset of the disease was on the patient's way home from aboard on February 21st,2016.Before then, She lived in Paramaribo, the capital of Suriname in South America, which is an epidemic area of Zika virus.The patient had exposure history,with red,diffuse rash on her head,face,neck and limbs,and once was diagnosed as allergic eruption because of no fever. The two blood samples were both tested negative yet We detected urine and saliva samples showed positive. With the evidence above, the patient was finally diagnosed as an imported Zika virus case. The spreading risk of this case was low due to the low temperature. Conclusionthere may be cases without fever or with blood sample tested RNA negative. As the weather gets warmer, missed diagnosis should be aware of, or the risk of spreading through mosquitos would increase. Therefore, in order to further improvement should lie in mosquito control and disease surveillance.
