Transmission: Aedes Aegypti and Aedes Albopictus transmit Zika virus between people. Zika research has also found cases of congenital transmission along with sex and possibly blood transfusion. 

Symptoms: Some cases will not have symptoms or they may be very mild. Symptoms include rash, fever, joint pain, red eyes, and muscle pain. There have only been a small amount of cases in which death occurs due to infection. Fetuses that have contracted Zika may be born with microcephaly and severe brain defects. Pregnant women may have miscarriages, stillbirths and other birth defects. Zika may also cause Guillain-Barre Syndrome in which a person's immune system attacks the nerve cells of that person. Rarely will Zika cause severe symptoms such as bleeding, bruising, slow blood clotting or swelling of the brain and spinal cord. 

Risk: Living within the tropical region which is most suitable for mosquito proliferation. 

Treatment: Currently there is no treatment but to treat the symptoms. If needed hospitals are supposed to be equipped to provide supportive care. 

Prevention: Be aware of current epidemiological trends when traveling and wear protective layers that protect against mosquito bites. Use mosquito repellent as well as avoiding being bitten.
