Zika is transmitted by the Aedes mosquitoes that transmit dengue, chikungunya. Hence the symptoms too are the same. Zika virus is rarely known to migrate from mother to her new born around the time of birth and to placenta. Its not yet surfaced of being transmitting from mother to baby by breast feeding.
