Complication	Timeframe	Likelihood
Guillain-Barre syndrome and/or other neurologic disorders	short term	low
Guillain-Barre syndrome (GBS) and other neurologic disorders are strongly associated with, and suspected to be caused by, Zika virus infection but the link is unestablished and studies are ongoing, including to elucidate a possible mechanism.[10][11][12][13] Current evidence estimates the incidence of GBS to be 24 cases per 100,000 persons infected with Zika.[45] Cases of acute myelitis, meningoencephalitis, and acute disseminated encephalomyelitis have been reported in patients with Zika virus infection.[26][229][230][231][232] A case of rapidly developing acute demyelinating polyneuropathy while the Zika virus was still present in the serum of the patient has been reported.[120] Acute sensory polyneuropathy has been reported in one patient during the active infectious phase.[233] Guillain-Barre syndrome
miscarriage	short term	low
Miscarriage has been reported in some women with Zika virus infection.[234] Miscarriage
uveitis	short term	low
May be a potential manifestation of Zika virus infection according to case reports.[235][236] Aqueous humor from the patient’s eye was positive for Zika virus RNA in reverse-transcription polymerase chain reaction (RT-PCR). Two cases of Zika-related bilateral hypertensive anterior acute uveitis have been reported.[237] Uveitis
cardiovascular complications	variable	low
A case of transient myocarditis has been associated with Zika virus infection.[238] Other possible cardiac complications related to Zika virus infection include arrhythmias, heart failure, and pericardial effusion.[239] One study suggests that congenital Zika virus infection may be associated with an increased risk of congenital heart disease, although further research is required.[240] Myocarditis
