Another, far more common mosquito could transmit the Zika virus, Brazilian researchers suggest. Currently, Zika is mainly transmitted from person to person via one species of mosquito, the Aedes aegypti.

Once infected with Zika, only a small proportion of people ever show symptoms, which most commonly include fever, rash, joint pain, and red eyes.
