Community involvement in Aedes albopictus management can be very efficient and result in raising awareness among citizens. Toward this end, a door-to-door campaign can encourage active community participation in vector control. The current study describes the results of an intervention where a KAP (knowledge, attitude, practices) survey tool was paired with a door-to-door campaign and was implemented as an intervention method in Vravrona area (Attica, Greece) before the release of sterile males (sterile insect technique, SIT) against Aedes albopictus. The KAP tool was used to shed light on the knowledge, practices, and attitudes of local community members in order to better prepare and motivate participation in household mosquito control and to assess current understanding of SIT. Each household also received specific information about mosquito source habitat in their own yards at the time of the initial KAP survey. These household data were complemented by standardized mosquito trapping in the municipality. Our findings indicate that citizens’ attitude toward SIT ranged from indecisive to fully supportive, while 77.5% of the respondents agreed that the SIT has many advantages over chemical control methods. Furthermore, the results demonstrate that using the door-to-door campaign as an intervention and prerelease method before SIT can suppress the initial mosquito population and potentially improve its efficacy. Lastly, we show that the presence of local municipality officials during door-to-door visits was associated with increased willingness from the residents to participate in the intervention.

“…In this sense, it has been hypothesized that such countries possibly experienced an aggravated COVID-19 pandemic due to socioeconomic ( de Sousa et al, 2020 ; Martins-FiIho et al, 2020 ) and health factors, such as other ongoing epidemics like dengue fever. Indeed, COVID-19/dengue co-infection has been reported in endemic and even in non-endemic countries, the consequences of such co-infection being mostly unknown at this point ( Butt et al, 2020 ; Estofolete et al, 2020 ; Lazzarini et al, 2020 ).…”

Highlights The SARS-CoV-2 and dengue syndemic is a reality in several countries worldwide. Prior dengue infection did not impact clinical parameters of COVID-19 patients. Active dengue fever worsened the pulmonary function of COVID-19 patients. Active and prior dengue infection were associated with an increase in blood glucose levels.

“…Moreover, several arboviruses have also experienced a (re-)emergence in temperate regions, mostly due to increased international travel and trade which have favored the movement of infected travelers along with disease vectors [ 3 ], the latter finding further favorable conditions for establishment and colonization thanks to global warming [ 4 , 5 ]. In particular, the exceptional expansion of the range of the highly invasive mosquito vector Aedes albopictus during the last 30 years has caused a Dengue outbreak with more than 37,000 human cases in China in 2014 [ 6 ], several autochthonous Dengue and Chikungunya cases in Europe in the last decade [ 7 , 8 , 9 , 10 , 11 ], and two Chikungunya outbreaks in Italy in 2007 and 2017 with more than 200 and 500 human cases, respectively [ 12 , 13 , 14 ].…”

Polymerase chain reaction (PCR)-based genotyping of mutations in the voltage-sensitive sodium channel (vssc) associated with resistance to pyrethroid insecticides is widely used and represents a potential early warning and monitoring system for insecticide resistance arising in mosquito populations, which are vectors of different human pathogens. In the secondary vector Aedes albopictus—an Asian species that has invaded and colonized the whole world, including temperate regions—sequencing of domain II of the vssc gene is still needed to detect the V1016G mutation associated with pyrethroid resistance. In this study we developed and tested a novel allele-specific PCR (AS-PCR) assay to genotype the V1016G mutation in this species and applied it to the analysis of wild populations from Italy. The results confirm the high accuracy of the novel AS-PCR and highlight frequencies of the V1016G allele as >5% in most sampling sites, with peaks of 20–45% in coastal touristic sites where pyrethroid treatments are extensively implemented, mostly for mosquito nuisance reduction. The high frequency of this mutation observed in Italian Ae. albopictus populations should serve as a warning bell, advocating for increased monitoring and management of a phenomenon which risks neutralizing the only weapon today available to counteract (risks of) arbovirus outbreaks.
