Objective
On March 2, 2020, the New York Times reported the first confirmed case of an infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the state of New York to be a woman from Manhattan. In the United States, as of April 2, 2020, New York has become the state with the most SARS-CoV-2 infections and deaths. By the end of April, 2020, there have been nearly 300,000 SARS-CoV-2 infections and over 17,000 deaths in the state of New York. This study aimed to investigate the number of pregnant and nonpregnant SARS-CoV-2 and coronavirus disease 2019 (COVID-19) cases during hospital admissions in the state of New York.
Study Design
This study focused on pregnant and nonpregnant SARS-CoV-2 and COVID-19 cases during hospital admissions. We used data that were collected at a large hospital group (14 hospitals) in the state of New York between March 2, 2020, and March 29, 2020. Routine SARS-CoV-2 testing was not performed. Data included week of admission, pregnancy status of the patient, and SARS-CoV-2 status (positive or negative). Subjects were diagnosed with SARS-CoV-2 on admission, during hospital stay, and after delivery. The institutional review board (IRB) determined that this study did not meet the definition of human subject research and that no IRB review was required.
Results
The Table and Figure show the SARS-CoV-2–positive cases by pregnancy status and weeks. A total of 21,980 admissions at 14 hospitals during the 4-week period was noted. Among those admissions, 3064 were pregnant or postpartum patients, and 18,916 were nonpregnant patients.
