We compared isolate infectivity and vector competence (VC) among thirty two A. aegypti-viral isolate pairs. Mosquito populations from high dengue incidence area exhibited overall greater VC than those from low dengue incidence area at 58.1% and 52.5%, respectively. On the other hand, the overall infection rates for the isolates ThNR2/772 (DF, 62.3%) and ThNR2/391 (DSS, 60.9%), were significantly higher than those for isolates ThNR2/406 (DF, 55.2%) and ThNR2/479 (DSS, 54.8%). These results suggest that the efficacy of dengue virus circulation was likely to vary according to the combination between the virus strains and origin of the mosquito strains, and this may have epidemiologic implications toward the incidence of flu-like classic dengue fever (DF) and dengue shock syndrome (DSS). specialized dengue virus disease severity vector competence THAILANDE 052 050 9 10 859 [13 ] 2020 https://www.documentation.ird.fr/hor/fdi:010079953 10.3390/pathogens9100859 [F B010079953] https://www.documentation.ird.fr/hor/fdi:010079953 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-11/010079953.pdf IRD - Base Horizon / Pleins textes 2020-12-08 2025-02-24 fdi:010079953 fre
