“…Specific primers ZIKV 1086 and ZIKV 1162c were used, with 5-FAM as the reporter dye for the probe (ZIKV 1107-FAM) [11]. Crossing point values were compared with a standard curve obtained from 10-fold serial dilutions of virus stock of known concentration [7]. …”

We investigated the susceptibility of an Italian population of Culex pipiens mosquitoes to Zika virus (ZIKV) infection, tested in parallel with Aedes aegypti, as a positive control. We analysed mosquitoes at 0, 3, 7, 10, 14, 20 and 24 days after an infectious blood meal. Viral RNA was detected in the body of Cx. pipiens up to three days post-infection, but not at later time points. Our results indicate that Cx. pipiens is not susceptible to ZIKV infection.

“…It is well accepted that Aedes species are the main vectors of ZIKV [5-7]. However, in order to assess the risk of spread of this infection to new areas, it is pivotal to investigate the possibility that mosquito species belonging to other genera could contribute to sustaining virus transmission.…”

“…This led to the initial hypothesis of a single transmitting species. There is also evidence of other mosquitoes in the Aedes genus with vectorial competence to transmit ZIKV [5,20,23,[25][26][27][28][29][30][31][32]. Due to its great abundance and antrophilia, Culex spp.…”

Zika (ZIKV) has spread rapidly throughout the world, causing serious epidemics. But, before the recent outbreak in Brazil, little was known about the virus or its mode of transmission. After ZIKV and microcephaly were associated in the Brazilian Northeast, virus spread caused international repercussions, generating the need to investigate other possibilities of transmission. Therefore, our objective was to identify the possible ways of ZIKV transmission described in the literature. A review of the published literature was carried out on the following databases: Scielo, Pubmed and Lilacs, related to ZIKV, from 1950 to 2006, and from 2006 to 2017. Only 46 publications were found in the period between 1950 to 2006. However, after the epidemics in the Yap Islands and in French Polynesia, more than 2000 publications were generated. The most common reported mode of transmission was the infected vector, especially those of the genus Aedes -A. aegypti was the most frequently cited. Some other possible vectors were cited as well, such as Culex spp.. However, studies suggest that this vector would not have the competence to transmit the ZIKV, which warrants further study. Other forms of documented transmission were through sexual intercourse, saliva, amniotic fluid, urine, semen, breast milk, blood transfusion and laboratory exposure. Given the great transmission potential of the ZIKV, its control has become a major challenge to global health. All these modes of transmission need to be further investigated to determine the relative weight of each one in any given epidemic.

“…albopictus, even though less competent than Ae. aegypti, can be a potential vector for Zika virus transmission [2,3] have further fuelled the concerns of possible importation of Zika virus, also in light of the upcoming Olympic and Paralympic Games in Brazil, a country with a large Zika virus disease epidemic. The European Centre for Disease Prevention and Control (ECDC) has addressed concerns related to disease occurrence in connection with travel to the Games in Brazil in a recent risk assessment [4].…”
