“…The Zika virus [ZIKV] is one of the most recent examples. Described for the first time in 1947, ZIKV had several local outbreaks, but in 2015 made the world's headlines after infected travelers went to see the 2014 world cup matches in Brazil, spreading the disease all over the world [10,11].…”

On 31 December 2019, China informed the World Health Organization they were facing a viral pneumonia epidemic of a new type of Coronavirus. Currently, 10 months later, more than 43,000,000 people have been infected, and about 1,150,000 deceased worldwide from the disease. Knowledge about the virus is updated daily, and its RNA was isolated from several human secretions, e.g., throat, saliva, pulmonary alveolar washing, and feces. So far, only one publication found the presence of SARS-CoV-2 in semen. In this 5-month cross-sectional study, we recruited 15 patients diagnosed with a positive nasal swab for SARS-CoV-2 with no or mild symptoms in our institution. A semen sample after a shower was retrieved and tested for viral RNA in the semen. The samples were tested for the viral RNA with RT-PCR with two different genetic probes. The samples were re-tested 24 h after the first test to confirm the results. The SARS-Cov-2 viral RNA was present in 1/15 patients [6.66%] in our sample. Even in a small sample, the RNA from SARS-CoV-2 can be isolated from human semen. This information should alert the scientific community and public health officials about a possible new form of transmission of the disease and long-term clinical effects on the population.

“…albopictus [5][6][7], both of which are widespread in tropical regions where ZIKV transmission has been reported. A total of 18 tropical species have been found to be infected in the field, with eight previously confirmed in the laboratory (reviewed in [8][9][10]). While both primary vectors, especially Ae.…”

Potential for Zika virus transmission by mosquitoes in temperate climates

Mosquito-borne Zika virus (ZIKV) transmission has almost exclusively been detected in the tropics despite the distributions of its primary vectors extending farther into temperate regions. Therefore, it is unknown whether ZIKV's range has reached a temperature-dependent limit, or if it can spread into temperate climates. Using field-collected mosquitoes for biological relevance, we found that two common temperate mosquito species, Aedes albopictus and Ochlerotatus detritus , were competent for ZIKV. We orally exposed mosquitoes to ZIKV and held them at between 17 and 31°C, estimated the time required for mosquitoes to become infectious, and applied these data to a ZIKV spatial risk model. We identified a minimum temperature threshold for the transmission of ZIKV by mosquitoes between 17 and 19°C. Using these data, we generated standardized basic reproduction number R 0 -based risk maps and we derived estimates for the length of the transmission season for recent and future climate conditions. Our standardized R 0 -based risk maps show potential risk of ZIKV transmission beyond the current observed range in southern USA, southern China and southern European countries. Transmission risk is simulated to increase over southern and Eastern Europe, northern USA and temperate regions of Asia (northern China, southern Japan) in future climate scenarios.

“…Although these two types of viruses have different host ranges, there are many similarities in virological classification and transmission methods [2]. While arboviruses are related to many diseases of animals and humans, such as dengue virus (DENV), Zika virus (ZIKV), and Japanese encephalitis virus (JEV), their horizontal transmission and vertical transmission mechanisms are relatively clear [3][4][5][6][7][8]. Significantly, the mode of transmission and ecological significance of the ISVs remain unknown 45 years after the discovery of ISVs by Stellar and Thomas [9,10].…”

Advances in technology have greatly stimulated the understanding of insect-specific viruses (ISVs). Unfortunately, most of these findings are based on sequencing technology, and laboratory data are scarce on the transmission dynamics of ISVs in nature and the potential effects of these viruses on arboviruses. Mesonivirus is a class of ISVs with a wide geographical distribution. Recently, our laboratory reported the isolation of a novel strain of mesonivirus, Yichang virus (YCV), from Culex mosquitoes, China. In this study, the experimental infection of YCV by the oral route for adult and larvae mosquitoes, and the vertical transmission has been conducted, which suggests that YCV could adopt a mixed-mode transmission. Controlled experiments showed that the infectivity of YCV depends on the mosquito species, virus dose, and infection route. The proliferation curve and tissue distribution of YCV in Cx. quinquefasciatus and Ae. albopictus showed that YCV is more susceptible to Ae. albopictus and is located in the midgut. Furthermore, we also assessed the interference of YCV with flaviviruses both in vitro and in vivo. YCV significantly inhibited the proliferation of DENV-2 and ZIKV, in cell culture, and reduced transmission rate of DENV-2 in Ae. albopictus. Our work provides insights into the transmission of ISVs in different mosquito species during ontogeny and their potential ability to interact with mosquito-borne viruses.
