Zika the Disease
Zika virus is an infection spread primarily through a mosquito bite from one of two species: Aedes aegypti and Aedes albopictus. A. aegypti is most likely to transmit Zika virus in the US, as this species can survive year-round in the warmer climates of states like Texas and Florida, has a greater affinity for biting humans, and has already been the main culprit in transmitting similar viruses, such as dengue, yellow fever, and West Nile virus.
Routes of Transmission
In addition to mosquito bites, Zika virus can be transmitted from an infected mother to her unborn child during pregnancy, through sexual contact, and via blood transfusion with infected blood. More information can be found on the Routes of Transmission page.
Only 20-25% of people infected with Zika virus will show symptoms, and these symptoms will likely be mild. To learn more about when symptoms may appear, how long they will last, and what the most common symptoms may be, visit our Symptoms page.
Diagnosis and Treatment
There is currently no specific treatment or vaccine for Zika virus. However, studies are underway to develop medical countermeasures against Zika. Go to the Diagnosis and Treatment page to learn about the current diagnostic methods that are being used and the treatment options available.
