Reservoir<unk>  virus is a mosquito-borne flavivirus closely related to the dengue and yellow<unk>  viruses. While mosquitoes are the vector, the main reservoir species remains unknown, though serological evidence has been found in both West African monkeys and rodents. Transmission Transmission is via the bite of mosquitoes from the genus Aedes, primarily Aedes aegypti in tropical regions. It has also been isolated from Ae. africanus, Ae. apicoargenteus, Ae. luteocephalus, Ae. albopictus, Ae. vittatus and Ae. furcifer. During the 2007 outbreak on Yap Island in the South Pacific, Aedes hensilli was the vector, while Aedes polynesiensis spread the virus in French Polynesia in 2013.<unk>  virus can also spread by sexual transmission from infected men to their partners.<unk>  virus has been isolated from semen samples, with one person having 100,000 times more virus in semen than blood or urine, two weeks after being infected. It is unclear why levels in semen can be higher than other body fluids, and it is also unclear how long infectious virus can remain in semen. There have also been cases of men with no symptoms of<unk>  virus infection transmitting the disease. The CDC has recommended that all men who have travelled to affected areas should wait at least 6 months before trying to attempt conception, regardless of whether they were ill. To date there have been no reported sexual transmissions from women to their sexual partners. Oral, anal or vaginal sex can spread the disease. Cases of vertical perinatal transmission have been reported. The CDC recommends that women with<unk>  should wait at least 8 weeks after they start having symptoms of disease before attempting to conceive. There have been no reported cases of transmission from breastfeeding, but infectious virus has been found in breast milk. Like other flaviviruses it could potentially be transmitted by blood transfusion and<unk> al affected countries have developed strategies to screen blood donors. The U.S. FDA has recommended universal screening of blood products for<unk> . The virus is detected in 3% of asymptomatic blood donors in French Polynesia.
