The California Department of Public Health (CDPH) has aligned its Zika testing guidelines with existing Centers for Disease Control (CDC) recommendations. Among the major changes is that asymptomatic pregnant women with recent but without ongoing exposure should be considered for testing based on careful risk assessment.
