Resumo: About 100 million passengers enter China via Shenzhen ports every year - such huge populations increase the risk of various infectious diseases, particularly mosquito-borne diseases, entering China. This paper reports the testing - monitoring of mosquito-borne diseases in febrile travelers through Shenzhen ports in 2013. The blood samples of 619 febrile cases were collected - the serum of each sample was used for the specific gene amplification - IgM antibody detection of five typical mosquito-borne pathogens: Dengue virus (DENV), Japanese encephalitis virus (JEV), Chikungunya virus (CHIKV), yellow fever virus (YFV), - West Nile Virus (WNV). Additionally, malaria was diagnosed by rapid diagnostic tests (RDTs). In total, 34 cases were detected of DENV infection (serotype I to IV), 17 cases of JEV infection, 2 cases of CHIKV infection, - 3 cases of malaria infection. No virus genes or IgM antibodies of YFV or WNV were detected in the samples. DENV, JEV - CHIKV cases were mainly from Southeast Asia, while malaria cases from Africa. DENV, JEV - CHIKV were the primary pathogens imported via Shenzhen ports. International travelers with mosquito-borne infections would accelerate the spread of these diseases, thus reinforcing the need for surveillance of mosquito-borne infections at ports should become a high priority.
