Answer: C
The virus is transmitted from human to human by the bites of infected female mosquitoes, primarily Aedes aegypti and Aedes albopictus. During the first week of infection, Zika virus can be found in the blood and passed from an infected person to another mosquito through mosquito bites.These are the same mosquitoes that spread dengue and chikungunya viruses.
Zika can be passed through sex from a person who has Zika to his or her partners. Zika can be passed through sex, even if the infected person does not have symptoms at the time.
