“…[31][32][33][34] In our study, we also noted the arrival of patients with Zika virus, yellow fever virus, and Rift Valley fever to mainland China since February, 2016. [12][13][14][15] Governments and the public health community should be aware of these new threats to prevent possible local epidemics.…”

“…[8][9][10] An outbreak of Chikungunya virus caused by infected travellers has been recorded in main land China, 11 and Zika virus, yellow fever, and Rift Valley fever have all been imported within the past 8 years. [12][13][14][15] In response to the increasing risk of imported infections, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) obliged all air and surface ports to do active surveillance of infections among arriving travellers. Systematic surveillance began in 2014 to reduce risk of autochthonous transmission and help to inform evidence-based advice for travellers.…”

“…According to the data from the report of infectious disease surveillance in 2015 by the Chinese Center for Disease Control and Prevention, the number of imported dengue and malaria cases have gradually increased since the 1990s. 1 China also encountered the importation of MERS, 2 Zika virus disease, 3 chikungunya, 4 yellow fever, 5 and Rift Valley fever, 6 and is still facing risks of other imported emerging infectious diseases.…”

To explore epidemiological characteristics of imported acute infectious diseases between 2011 and 2016 in Zhejiang province, China. Data of imported infectious diseases from 2011 to 2016 was collected from the China Information System for Disease Control and Prevention in Zhejiang province, and subsequently analyzed for epidemiological characteristics. A survey was conducted to investigate clinicians' abilities to diagnose these diseases in Zhejiang province. From 2011 to 2016, 1,241 cases of imported acute infectious disease were reported in Zhejiang province, including 1,078 malaria cases, 156 dengue cases, three chikungunya fever cases and four Zika cases. Between 2011 and 2016, incidences of these diseases increased ( < 0.001). For malaria, male adults for labor export were the most affected group. Seasonal fluctuation was not obvious. was the main malaria type (822 cases) and most cases were acquired from African Region (791/822, 96.1%). cases (194 cases) were mainly from African Region (78/194, 40.2%) and South-East Asia Region (51/194, 26.3%). Meanwhile, for dengue, adults and tourists were the most affected groups. The incidence of dengue was particularly high in August and October. The percent of correct clinician responses in the survey of diagnosis knowledge was 54.6% (standard deviation = 21.0%); this percentage was particularly low in general practitioners and clinicians from township hospitals. The capabilities of clinicians to diagnose these diseases were low and should be improved. Efforts should be made in improving and disseminating proper preventive measures of high-risk populations, surveillance of imported cases, and prevention and control of local epidemics.

“…32,33 Although there is a very short evolutionary distance between our strains and the Venezuela imported strain KU744693.1-VE Ganxian, the diversity of the strains is apparent, and the latter is nearer to KJ776791.1-H/PF/2013 French Polynesian strains. 31,34 Currently, all cases reported in China seem to be imported from South America and Pacific islands, which also indicates there was a great diversity of strains circulating during early 2016 in Venezuela. Our strains are more similar to the strains circulating in South America in late 2015, where there were more strains isolated from patients.…”

Epidemiologic investigation of a family cluster of imported ZIKV cases in Guangdong, China: probable human-to-human transmission

Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that can potentially threaten South China. A Chinese family of four returning from Venezuela to China was found to be positive for ZIKV when the youngest son's fever was first detected at an airport immigration inspection. They were isolated temporarily in a local hospital in Enping city, Guangdong province, where their clinical data were recorded and urine and saliva were collected to isolate ZIKV and to obtain viral sequences. All of them except the mother presented mild symptoms of rash and fever. Envelope gene sequences from the father, daughter and son were completely identical. Phylogenetic analysis demonstrated that this strain is similar to several imported strains reported in recent months, which are all clustered into a group isolated from 2015 ZIKA outbreaks in Brazil. Together with the climatic features in Venezuela, New York and Guangdong in February, it can be concluded that our subjects are imported cases from Venezuela. With the same viral sequence being shared between family members, neither direct human-to-human nor vector transmission can be ruled out in this study, but the former seems more likely. Although our subjects had mild illness, epidemiologists and public health officials should be aware of the risk of further expansion of ZIKV transmission by local competent vectors.
