  abstract = {{B}ackground {T}he global spread of {A}edes albopictus has exposed new geographical areas to the risk of dengue and chikungunya virus transmission. {S}everal autochthonous transmission events have occurred in recent decades in {S}outhern {E}urope and many indicators suggest that it will become more frequent in this region in the future. {E}nvironmental, socioeconomic and climatic factors are generally considered to trigger the emergence of these viruses. {A}ccordingly, a greater knowledge of the determinants of this emergence in a {E}uropean context is necessary to develop adapted surveillance and control strategies, and public health interventions. {M}ethodology/{P}rincipal findings {U}sing {F}rench surveillance data collected from between 2010 and 2018 in areas of {S}outhern {F}rance where {A}e. albopictus is already established, we assessed factors associated with the autochthonous transmission of dengue and chikungunya. {C}ases leading to autochthonous transmission were compared with those without subsequent transmission using binomial regression. {W}e identified a long reporting delay (>= 21 days) of imported cases to local health authorities as the main driver for autochthonous transmission of dengue and chikungunya in {S}outhern {F}rance. {T}he presence of wooded areas around the cases' place of residence and the accumulation of heat during the season also increased the risk of autochthonous arbovirus transmission. {C}onclusions {O}ur findings could inform policy-makers when developing strategies to the emerging threats of dengue and chikungunya in {S}outhern {E}urope and can be extrapolated in this area to other viruses such as {Z}ika and yellow fever, which share the same vector. {F}urthermore, our results allow a more accurate characterization of the environments most at risk, and highlight the importance of implementing surveillance systems which ensure the timely reporting and of imported cases and swift interventions.},
