Approximate annual deliveries were reported by each site
2018 data from the WA-DOH birth data dashboard tool (Birth Certificate Data, 2000–2018, Community Health Assessment Tool)
Case counts of confirmed SARS-CoV-2 cases among females aged 18 to 50 years who were pregnant at the time of infection were provided by the WA-DOH from March 1, 2020, to June 30, 2020. Pregnancy status was ascertained through case interviews or by local health jurisdiction investigation. In 35% of SARS-CoV-2 case records among females aged 18 to 50 years, pregnancy status was unknown or missing
Direct linking of WA-CPC and WA-DOH cases was not possible, so the exact overlap of WA-CPC and WA-DOH identified cases is unknown
The total number of live births in Washington State in 2018 was 84,046, but 40 cases were not attributed to an ACH region.
