Dengue is hyperendemic in Indonesia. In 2015, reported cases of dengue fever doubled those of 2014 in the Jambi municipality of Sumatra. We examined viral aetiology and its relationship with disease outcome in Jambi. Dengue-suspected patients' sera were collected and NS1 detection and IgM/IgG serology were performed. Dengue virus (DENV) serotyping was performed using real-time RT-PCR. Envelope genes were sequenced to determine the genotypes of DENV. Clinical, haematologic, and demographic data were recorded. Of 210 dengue-suspected patients, 107 were confirmed. The disease manifested as Dengue Fever (62%), Dengue Haemorrhagic Fever (36%), and Dengue Shock Syndrome (2%). The serotypes of 94 DENV were determined. All DENV serotypes were detected with DENV-1 as the predominant serotype (66%). Genotypically, the DENV-1 viruses belong to Genotype I, DENV-2 was of Cosmopolitan genotype, DENV-3 as Genotype I, and DENV-4 belonged to Genotype II. Comparison with historical data revealed serotype predominance switched from DENV-3 to DENV-1, and the replacement of Genotype IV of DENV-1 with Genotype I. In summary, DENV-1 predominated during the 2015 dengue outbreak in Jambi. The full spectrum of dengue disease occurred and was characterized by a switch in predominant serotypes.
登革热在印度尼西亚高度流行。2015年,苏门答腊占碑市报告的登革热病例较2014年翻了一番。我们对占碑市的病毒病因及其与疾病结局的关系进行了研究。收集了疑似登革热患者的血清,并进行了NS1检测和IgM/IgG血清学检测。使用实时逆转录聚合酶链反应(RT-PCR)进行登革病毒(DENV)血清分型。对包膜基因进行测序以确定DENV的基因型。记录临床、血液学和人口统计学数据。在210名疑似登革热患者中,107例得到确诊。疾病表现为登革热(62%)、登革出血热(36%)和登革休克综合征(2%)。确定了94株DENV的血清型。所有DENV血清型均被检测到,其中DENV-1为主要血清型(66%)。在基因型方面,DENV-1病毒属于基因型I,DENV-2为泛基因型,DENV-3为基因型I,DENV-4属于基因型II。与历史数据比较显示,血清型优势从DENV-3转变为DENV-1,并且DENV-1的基因型IV被基因型I取代。总之,在2015年占碑市登革热疫情期间,DENV-1占主导地位。登革热疾病的全谱出现,其特征是主要血清型发生了转变。
