Timeline of symptom onset and resolution, laboratory testing, COVID-19 hospital admission, and delivery for 46 pregnant patients

Time is indicated on the x-axis and is measured by gestational age in weeks. Each line of the y-axis reflects an individual patient. Gestational age of the first positive SARS-CoV-2 test (red star), length of symptoms (black lines), gestational age at symptom onset (black dot), gestational age or days postpartum at symptom resolution (black dot if resolved and a black arrow if ongoing at last encounter [censoring]), length of COVID-19 hospitalizations (gray bar), and gestational age at delivery (blue vertical line) are indicated for each patient, as applicable. Three patients were asymptomatic. Of the 7 patients hospitalized for COVID-19–associated respiratory concerns, 6 were severe (Table 3).
