Biologist Brian Foy published a case study, which claims vector, you the first documented evidence of an insect-borne diseases among people through sexual contact is common.
Unfortunately, the research methods for Foy, a bit more intimate than most would prefer people were. In the fall of 2008, Foy returned from a trip to Senegal, where he collected mosquitoes for malaria research. Over five days later he was virus - a rare disorder given mosquitoes ill with what later proved to be as Zika. And so also not his wife long afterwards. The catch: Joy Chilson Foy had not been the Senegal.
There is no direct evidence that Foy's wife was infected through sexual contact, but the evidence is strong. It is very unlikely that it was infected by a bite of a mosquito, which her husband first bit; the three tropical Aedes known to Zika transferred mosquito of species cannot live in northern Colorado, and in addition the virus has to complete a 2-week life cycle within the insect before it can infect the next people Foy's wife fell ill just 9 days after his return. And Yes, as the paper puts it, "patients 1 and 3 reported that vaginal sexual intercourse in the days following patients 1 home returned but before the start of his clinical illness." ("My wife wasn't happy happened to what then," adds Foy.)
Foy and his co-authors believe that sexual transmission of mosquito-borne virus never before been reported although there was evidence from the literature, that it might be possible. Boar experimentally infected with Japanese encephalitis virus, for example, the virus in their semen and female pigs could be infected artificially inseminated with it.
Scientists know that many insect can orally as also transmitted communicable pathogens, says medical entomologist Paul Reiter of the Institut Pasteur in Paris. Even if it documented it is no great surprise that infected semen in the vagina may lodged an infection, lead, not before, he says.
Science now: sex after an excursion first scientific results
