“…The newly-detected strain SA-JD-AS-BM4-16-2-A9 was obtained from mosquitoes collected in a building under construction in the Bani-Malek-4 District, Al-Sharafyia Municipality, which is only 15 km away from the King Abdulaziz International Airport. Notably, in the phylogenetic tree, it is clustered with the strain D2/Hu/SaudiArabia/NIID/22/ 2018 (LC416035) detected from a Japanese traveler returning from Saudi Arabia in 2018 (Matsui et al, 2019), and was sister to the strain D2/Saudi Arabia/1407aTw_Saudi Arabia (KT175140) FIGURE 4 | Phylogenetic tree generated by Bayesian analysis of dengue virus 2 (DENV-2) Cosmopolitan genotype complete envelope gene.

BackgroundMosquito-borne diseases are rapidly spreading due to increasing international travel and trade. Routine mosquito surveillance and screening for mosquito-borne pathogens can be early indicators for local disease transmission and outbreaks. However, arbovirus detection in mosquito vectors has rarely been reported in Saudi Arabia.MethodsA total of 769,541 Aedes and Culex mosquitoes were collected by Black Hole traps during routine mosquito surveillance in the first half of 2016. Culex. quinquefasciatus and Ae. aegypti were the most prevalent species observed. Twenty-five and 24 randomly selected pools of Ae. aegypti and Cx. quinquefasciatus, respectively, were screened for arboviruses by RT-PCR.ResultsDengue 2 (DENV-2) and four strains of insect-specific flaviviruses, including one of cell-fusing agent virus (CFAV) and three of Phlebotomus-associated flavivirus (PAFV) were detected in pools of Ae. aegypti. We also detected 10 strains of Culex flavivirus (CxFV) in pools of Cx. quinquefasciatus. Phylogenetic analysis using whole genome sequences placed the DENV strain into the cosmopolitan 1 sub-DENV-2 genotype, and the CxFVs into the African/Caribbean/Latin American genotype. These analyses also showed that the DENV-2 strain detected in the present study was closely related to strains detected in China in 2014 and in Japan in 2018, which suggests frequent movement of DENV-2 strains among these countries. Furthermore, the phylogenetic analysis suggested at least five introductions of DENV-2 into Saudi Arabia from 2014 through 2018, most probably from India.ConclusionsTo our knowledge, this study reports the first detection of four arboviruses DENV, CFAV, PAFV, and CxFV in mosquitoes in Saudi Arabia, which shows that they are co-circulating in Jeddah. Our findings show a need for widespread mosquito-based arbovirus surveillance programs in Saudi Arabia, which will improve our understanding of the transmission dynamics of the mosquito-borne arboviruses within the country and help early predict and mitigate the risk of human infections and outbreaks.

“…One of the social demographics and population factors is tourism that have long been studied as the contributing factor to the transmission of infectious disease, as reported by study in South Korea that international travellers from South East Asia are associated with the DF occurence during 2006 -2015 (Cho et al 2018). Another dengue case found from traveller who came from Saudi Arabia whose type-2 virus strain clustered with isolates of Singapore and India (Matsui et al 2019). The impact of mobility and tourism not only exacerbated local transmission but also have driven global spread of DF, for instance the research in 2018 found significant association between the DF incidence in Bali with the imported cases in Australia (Xu et al 2018).…”

As a national and international tourism destination, Badung district has recorded the highest dengue fever (DF) in Bali Province with multiple suspected influencing factors. This research presents the distribution of dengue fever (DF) incidence in Badung district and analyses its association with climate and visitors. The monthly data of DF surveillance, climate and reported number of visitors during January 2013 – December 2017 was analysed using Poisson Regression. 10689 new DF cases were notified from January 2013 to December 2017 while 2016 was recorded as the heaviest DF incidence. Monthly DF cases have positive association with average temperature, precipitation, humidity and local visitors. While negative association was shown between DF cases with foreign visitors. This study underlines the urgency to integrate climate and tourism for dengue fever control. Further study is recommended to take both factors together with population mobility at finer spatial and time unit of analysis.
