There is no prevention or treatment. Travelers to dangerous areas are urged to prevent mosquito bites by using mosquito repellant and covering exposed skin.
The aedis aegyptia mosquito, which transmits the disease, bites all day long, so individuals need to reapply that repellant and not let their guard down. Aedes albopictus mosquitoes, which are found throughout the U.S. and are known for transmitting dengue fever and chikungunya, may also transmit the virus, the CDC said Friday.
However, mosquito bites and mother to unborn baby aren't the only ways this virus is transmitted. The new CDC report notes documented cases of infection from sexual transmission, blood transfusion and laboratory exposure.
Stephen Higgs, president of the American Society of Tropical Medicine and Hygiene, told CNN that once a person is infected with the virus, it is likely that they will develop an immunity to future infection.
