Data on COVID-19 during Pregnancy
Monitoring the impact of COVID-19 during pregnancy can protect pregnant women and their babies.
An MMWR study suggests that pregnant women with COVID-19 are more likely to be hospitalized and are at increased risk for intensive care unit (ICU) admission and receipt of mechanical ventilation than nonpregnant women. Risk of death is similar for both groups. But much remains unknown.
CDC is working with state, local, and territorial health departments and external partners to learn more about COVID-19 during pregnancy. Health departments that are notified of COVID-19 cases in pregnant women may collect more information using an optional modulepdf icon in addition to the case report form. CDC will use this information to update clinical guidance for pregnant women and their infants.

About the Data
This page is updated weekly on Thursday at 1:00pm ET based on data collected by Tuesday at 12:30pm ET. The cases reported are only confirmed cases with laboratory evidence of SARS-CoV-2 infection.
There are currently 56 U.S.-affiliated jurisdictions reporting cases of COVID-19. This includes 50 states, District of Columbia, Guam, New York City, the Northern Mariana Islands, Puerto Rico, and the U.S Virgin Islands.
Because only about a third of case report forms include information on pregnancy status, these numbers likely do not include all pregnant women with COVID-19 in the United States and must be interpreted with caution. The completeness of this variable continues to improve each week. Increases in the total number of cases of COVID-19 among pregnant women are largely due to the updating of pregnancy status among already reported cases. Case numbers reported on other websites may differ from what is posted on CDC’s website because CDC’s overall case numbers are validated through a confirmation process with each jurisdiction. Differences between reporting jurisdictions and CDC’s website may occur because of the timing of reporting and website updates. The process used for finding and confirming cases displayed by other sites may differ. Case counts may fluctuate from week to week due to data quality and cleaning processes.
As of October 2020, CDC will exclude reports of cases of COVID-19 among pregnant women who are younger than age 9 and older than age 54 in the weekly reporting. Based on review of data quality, cases reported as pregnant with ages less than 9 or greater than 54 are less likely to be true pregnancies, and more likely to be data errors. Cases with unknown age are still included.
