Assessing the Risk of Dengue Virus Local Transmission: Study on Vector Competence of Italian <i>Aedes albopictus</i>
The frequency of locally transmitted dengue virus (DENV) infections has increased in Europe in recent years, facilitated by the invasive mosquito species <i>Aedes albopictus</i>, which is well established in a large area of Europe. In Italy, the first indigenous dengue outbreak was repor...

| description | The frequency of locally transmitted dengue virus (DENV) infections has increased in Europe in recent years, facilitated by the invasive mosquito species <i>Aedes albopictus</i>, which is well established in a large area of Europe. In Italy, the first indigenous dengue outbreak was reported in August 2020 with 11 locally acquired cases in the Veneto region (northeast Italy), caused by a DENV-1 viral strain closely related to a previously described strain circulating in Singapore and China. In this study, we evaluated the vector competence of two Italian populations of <i>Ae. albopictus</i> compared to an <i>Ae. aegypti</i> lab colony. We performed experimental infections using a DENV-1 strain that is phylogenetically close to the strain responsible for the 2020 Italian autochthonous outbreak. Our results showed that local <i>Ae. albopictus</i> is susceptible to infection and is able to transmit the virus, confirming the relevant risk of possible outbreaks starting from an imported case. |
