Typical Zika illness is characterized by low-grade fever, maculopapular rash, arthralgia and often conjunctivitis; Guillain-Barré syndrome is a recognized post-infectious complication, so it can be seen in association with Zika infection [Karwowski, 2016, PMID 27009036; Muñoz, 2017, PMID 29267923]. Petechial rash is not a usual feature of Zika fever (the rash is generally non-petechial), making this the exception among the listed options.
