Zika virus can be spread during sex by a man infected with Zika to his partners.

To prevent spreading Zika through sex, couples should use a condom every time they have sex, if the man has been diagnosed with zika or has the signs and symptoms of zika .

the possible transmission route is through the Aedes species mosquito. but other available transmission mode could be through sexual intercourse, mother to child transmission and blood transfusion. you can visit CDC for more information.

Zika virus is transmitted by moskitus Aedes africanus, Aedes apicoargenteus, Aedes furcifer, Aedes hensilli, Aedes luteocephalus. After entering in skin, it attaches and infects Dendritic cell in skin and inside these cells it spreads into lymphatic nodes and into blood. There was one case of sexual transmission and one case vertical transmission from mother to fetus.

zika virus can transmitted through the bite of an infected Aedes species mosquito. A pregnant woman can pass Zika virus to her fetus during pregnancy , which cause of microcephaly and other severe fetal brain defects. also Zika virus can be spread by a man to his sex partners , Finally through blood transfusion 

Through mosquito bites

Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito (A. aegypti and A. albopictus). These are the same mosquitoes that spread dengue and chikungunya viruses.

From mother to child

A pregnant woman can pass Zika virus to her fetus during pregnancy. Zika is a cause of microcephaly and other severe fetal brain defects, and we are studying the full range of other potential health problems that Zika virus infection during pregnancy may cause.

A pregnant woman already infected with Zika virus near the time of delivery can pass on the virus to her newborn around the time of birth.

To date, there are no reports of infants getting Zika virus through breastfeeding. Because of the benefits of breastfeeding, mothers are encouraged to breastfeed even in areas where Zika virus is found.

Through sexual contact

Zika virus can be spread by a man to his sex partners.

Zika virus can be spread by a man to his partner during sex. In known cases of sexual transmission, the men had Zika symptoms. The virus can be spread when the man has symptoms, before symptoms start, and after symptoms end. The virus can stay in semen longer than in blood. We do not know if Zika can be spread through oral sex. For more information visit:

Normalmente este virus   es muy fuerte en zonaa calidas, se propaga fácilmente y se transmite en su mayoría por picadura de zancudo, y el mismo ataca lo más débil q tenga tu cuerpo, es decir su has sufrido de alguna enfermedad la despierta y la empeorará. Por ejemplo yo sufro para subir las defensas, y lo primero que hizo fue bajarlas,  .. . lo más difícil de este virus es q puede durar más de 2 años en el cuerpo..... Después de pasar el malestar quedas muy débil.. ....es un virus muy fuerte .....este virus es la evolución del chikunguña

Dear Sir/Madam

Zika virus is a single-stranded RNA virus of the Flaviviridae family, genus Flavivirus. Zika virus is transmitted to humans primarily through the bite of an infected Aedes species mosquito. The mosquito vectors typically breed in domestic water-holding containers; they are aggressive daytime biters and feed both indoors and outdoors near dwellings. Nonhuman and human primates are likely the main reservoirs of the virus, and anthroponotic (human-to-vector-to-human) transmission occurs during outbreaks. Perinatal and possible sexual transmission has also been reported. Transfusion-associated transmission is possible as Zika virus RNA has been identified in asymptomatic blood donors during an ongoing outbreak (CDC info)..

ZIKV is an arbovirus and therefore, the principal mechanism of trasnsmission to humans is by vector bites. The ZIKV vectors are Aedes aegypti and Aedes albopictus mosquitoes. Although ZIKV is an arbovirus, no vectored transmission have been reported, the most well documented mechaniisms are:

sexual transmission in general from male to female;

Congenital transmiission

Perinatal transmission occurring during the delivery;

Blood transfusion - since approximately 80% of ZIKV are asymptomatic the risk of blood transfusion during blood donation is high;

Solid organ transplant is also suggested as a potential mechaniism of ZIKV transmission;

Probably yes. ZIKV asymptomatic infections in humans are equivalent or act as intermediate host, therefore if the viremia is high the vector can become infected. Thus, asymptomatic viremic person can plays a similar role of intermediate host to asymptomatic ZIKV infections.

Are there experiments exposing infected humans or other animals to Aedes aegypti/albopictus bites?

Zika virus has many modes to transmit the infection, including the bite of an Aedes mosquito after injecting the virus through saliva and this considers the most common way to transmit the disease. The other modes are the vertical transmission of the virus from the infected mother to her fetus

For Dr. Marcondes, this review is quite good. Many mammals develop antibodies. Passaged and engineered Zika virus has been developed for using mouse model. "Previous serologic data has shown that a wide array of large animals have an immunologic response to Zika virus, including water buffalo, goats, NHP, lions, sheep, and wildebeest." Non-human primates are the animal used for gestation studies. Humans may develop severe illness, and appear to be unique in this. Zika antibodies are common in humans throughout Asia and Africa where Aedes mosquitos exist.

It's possible (I suspect it is likely) that serious Zika virus illness is associated with CCR5 mutations that disable a mechanism that suppresses certain virus infections in the brain. This is true for West Nile virus. But this is, at present, unproven. Disabling mutations of this gene also help protect against HIV infection, and are associated with better cognitive scores.
