Screening for Zika virus infection is typically only recommended in symptomatic patients (particularly pregnant women), but asymptomatic pregnant women who meet certain epidemiological criteria may also be considered for testing.[161] Some guidelines may recommend screening all exposed pregnant women as most infections are asymptomatic and clinical manifestations are non-specific.[190] Consult your local guidance for more information as testing recommendations may vary depending on the current epidemiological situation.

One study found that most asymptomatic pregnant women who were tested in the US who had travelled to, or moved from, areas with active Zika virus transmission did not have Zika virus infection.[191] One large-scale antenatal Zika screening programme identified that only 0.2% of pregnant women who were at risk of infection from recent travel to a Zika-affected area became infected.[192]
