ADE as a riks factor for ZIKV derived complications

• There is biological evidence of ADE

Castanha PMS et al, 2017

• There is a need to promote understanding of the role ofcommorbidities and co infections on ZIKV clinicalspectrum.

• ADE still remains as a potential risk factor which clinicalimpact must be studied.
