Molecular detection of Indian Ocean Lineage Chikungunya virus RNA in field collected Culex quinquefasciatus Say from Bangkok, Thailand but no evidence of virus replication.

ABSTRACT: Following an outbreak of chikungunya virus (CHIKV) infections in Thailand in 2019, numerous cases of CHIKV infection have been diagnosed in Bangkok, the capital of the country. In our previous investigation of the vectors for disease transmission, we found natural infection of CHIKV in both male and female Aedes aegypti mosquitoes collected from the outbreak areas in Bangkok. Some reports mentioned the detection of CHIKV in Culex mosquitoes. In Thailand, the Culex quinquefasciatus Say mosquito is a common species found in urban and rural settings that coexists with Ae. aegypti. However, the role of Cx. quinquefasciatus mosquitoes in the spread of the Indian Ocean Lineage (IOL) of CHIKV in Thailand has never been investigated. In this study, Cx. quinquefasciatus were collected (16 males and
