Abstract:
Objective To investigate the epidemiological, clinical and pathogenic characteristics and prognosis of the first imported case of Chikungunya fever in China in 2008. Methods Epidemiological and clinical data of this mate adult patient were analyzed retrospectively. Chikungunya virus (CHIKV)-IgM was detected using enzyme linked immunosorbent assay (ELISA) and colloidal gold immunoassay. CHIKV-RNA was detected using real-time fluorescent polymerase chain reaction (RT-PCR). Results This patient had onset of fever on March 2 in 2008 and lasted for 5 days. In addition, he felt joint and muscle pains, headache and found generalized engorged maculopapule. The laboratory tests showed leukopenia and thrombocytopenia. CHIKV-IgM was detected positive at day 9 after the onset and CHIKV-RNA was all positive at day 3, 5, 7, 9 after the onset. A 575 bp fragment of RT-PCR product was sequenced and detected the nucleotide homology was 99% compared with CHIKV sequences in GenBank. The patient recovered with symptomatic supportive treatment.Conclusion This imported case of Chikungunya virus infection is reported for the first time in China.It shows similar clinical manifestations with dengue fever.
