The Trump administration’s shakeup of the Centers for Disease Control and Prevention (CDC) has forced Mississippi to stop gathering critical data on women’s experiences before, during and after pregnancy – even as the state recently declared a public health emergency over its surging infant mortality rate.

Mississippi has suspended data collection for Pregnancy Risk Assessment Monitoring System (Prams), a national database that has been integral to policymaking on maternal and infant health for nearly four decades, the Guardian has learned.

Prams functions as a partnership between state-level health officials and a little-known but influential CDC agency called the Division of Reproductive Health, which has lost most of its staff – nearly 100 people – in the Trump administration’s purges of federal workers, according to records in a lawsuit filed by several Democratic-led states over the purges.
