It can result in severe neurological conditions, such as Guillain-Barré Syndrome and Zika congenital syndrome, including microcephaly. Responding to the Zika crisis has shed light on much bigger health systems challenges in affected countries, including lack of access to comprehensive contraceptive information and services in some communities affected or threatened by the Zika virus.
