Background: Scientific overwhelming evidence confirms that the prevalence and incidence of mosquito-borne viruses such as chikungunya (CHIK) are dramatically increasing in Middle- Eastern countries including Iran.Methods: I n t his r eview a rticle, u sing r elevant k eywords (“Chikungunya” OR “CHIKV” OR “Aedes albopictus” OR “Aedes aegypti”), available literature was searched to collect data related to the reports of CHIK and its main vectors, Aedes albopictus and Ae. aegypti, in Iran and 15 neighboring countries: Pakistan, Afghanistan, Turkmenistan, Russia, Azerbaijan, Armenia, Turkey, Iraq, Kuwait, Bahrain, Qatar, United Arab Emirates (UAE), Oman, Saudi Arabia, and Yemen.Results: CHIK was reported in neighboring countries such as Pakistan, Turkey, Russia, Saudi Arabia, Yemen, Oman, Qatar, and Iraq. Furthermore, presumably introduced in 2019, CHIK was reported in 11 provinces in Iran with overall seropositivity of 17.23% in humans over the past three years. The mosquitoes, Ae. albopictus and Ae. aegypti, have recently been reported in the southeast and south of Iran.Conclusion: Given the change in climate, even if the density of the vectors is still limited, there is no guarantee that their population will not spread much more in the coming years. This emphasizes the urgent need to strengthen the surveillance system for the vectors, and sustained surveillance of CHIK infections in mosquitoes and humans, preferably in a collaborative international project.

Background: Aedes mosquitoes transmit important arboviral diseases such as dengue to humans. This study was conducted to determine dengue virus infection in Aedes mosquitoes, emphasizing Aedes aegypti by Reverse Transcriptase-Polymerase Chain Reaction Assay from different regions in Southern Iran.Methods: Aedes samples were collected by standard methods from different habitats of Hormozgan province, Southern Iran, in 2016-2017, and identified by morphological characteristics. In this study, TissueLyserII was used to homogenize the collected mosquitoes. In addition, the RT-PCR technique was used to identify dengue virus RNA.Results: Overall, 1351 larval and adult Aedes mosquitoes were collected from five sites in Hormozgan Province, including 452 adults and 899 larvae. Five species from Aedes genera were collected (Ae. aegypti, Ae. vittatus, Ae. caballus, Ae. caspius, Ae. vexans). The investigations of dengue virus infection in Aedes mosquitoes showed no dengue virus infection in this species.Conclusion: This study provides important information about Aedes mosquitoes. Vector control strategies must be emphasized and prioritized. Such actions prevent the establishment of Aedes mosquitoes and the spread of arboviral diseases in new areas. In addition, early detection of arboviruses in vectors and entomological monitoring can enhance the control measures for arbovirus diseases.
