Objective To provide scientific evidences for Zika virus detection by clarifying the means by which Zika virus was discharged and the duration of corresponding processes. Methods Various samples of Zika cases were collected at different times and detected by using real-time RT-PCR. The positive samples were inoculated into cells and suckling mice through intracranial injection. The whole genome se-quences of those isolated Zika virus strain were sequenced and the results were further analyzed by comparing with the sequences of Zika virus from GenBank. Results The positive rates of Zika virus in urine, saliva and serum samples were 82. 4% (14/17), 82. 4% (14/17) and 52. 9% (9/17) respectively. The longest period of detected presence of Zika virus was found in urine samples amongst the three types of samples, fol-lowed by saliva and serum samples. Six Zika virus strains were isolated from 9 positive serum samples. Phy-logenetic analysis showed that the six genomes of Zika virus all belonged to Asia lineage, but located in two branches by Samoa and Venezuela strains. Conclusion This study indicated that urine, saliva and serum all could be used as the samples for routine detection of Zika virus. Urine and saliva samples showed higher detection rates of Zika virus RNA in comparison to serum samples, while Zika virus could be easily isolated from positive serum samples. Suckling mice were better for Zika virus isolation than cell lines.

Objective To establish a method for the isolation of Zika virus and to gather experi-ences for viral isolation. Methods Suckling mice at age 1-3 days were inoculated with serum samples posi-tive for Zika virus through intracranial injection. All mice were sacrificed 6 days after the injection. Viral nu-cleic acids were extracted from brain, heart, liver, spleen, lung, kidney, muscle, skin and intestine tissue samples and analyzed by real-time RT-PCR. The supernatants of brain tissues positive for Zika virus were used for subculturing. Nested PCR was performed to amplify the NS5 gene of the isolated virus. The se-quences of NS5 gene were analyzed by using MEGA6. 0 software. Results All of the tissue samples were positive for Zika virus. Higher viral loads were detected in heart and brain tissue samples with cycle thresh-old (Ct) values of 24. 4 and 25. 3, respectively. The second generation of Zika virus was identified in suck-ling mice brain tissues 2 days after infection by using real-time RT-PCR. The amplified product of nested PCR was 972 bp in length. Sequencing analysis showed that the isolated Zika virus ( GDZ16002 strain) be-longed to the Asian lineage. Conclusion A strain of Zika virus was successfully isolated in China by using intracranial injection via a suckling mouse model. The isolated Zika virus belonged to the Asian lineage.

OBJECTIVETo identify clinical characteristics of hospitalized laboratory-confirmed influenza cases of children under 15 years old, and their risk factors of influenza infection.
METHODSAnalyzing the reports of hospitalized laboratory-confirmed influenza cases of children under 15 years old who were detected by the sentinel surveillance systems in 10 provinces from December 2009 to June 2014. Such data as their demographic, medical history, clinical symptoms and signs, treatment and outcome were collected using questionnaires, with their clinical characteristics and their risk factors of influenza infection described.
RESULTSOf the 2 937 severe acute respiratory infection inpatients, 190 (6.5%) were laboratory-confirmed influenza cases. 123 (64.7%) of such confirmed cases were male, and 139 (73.2%) were children under 5 years old, with age median of 3.0 years (IQR: 1.0-5.0 years). 20 (10.5%) of them had at least one chronic medical condition, mostly chronic cardiovascular disease (3.2%), immunosuppressive disease (3.2%), and cancer/tumor (2.6%). Most common clinical symptoms of the cases were fever (92.6%) and cough (88.8%), of which abnormal pulmonary auscultation (51.1%) and abnormal chest X-ray performance (36.1%) were the most common clinical signs. 29 cases (15.8%) had complications, of which pneumonia (15.3%) was most common. 16 cases (8.6%) used antiviral drugs, and 4 cases (2.2%) were admitted into ICU. Risk factor analysis suggested that age < 6 months (OR = 0.406, 95% CI: 0.203-0.815) was a protective factor against influenza infection; and age 5-9 years old (OR = 2.535, 95% CI: 1.059-6.066) was a risk factor for influenza infection.
CONCLUSIONHospitalized laboratory-confirmed influenza cases were found mostly in children under 5 years old. Risk exposure for influenza infection varied among age groups.
