Monarez, a microbiologist and infectious disease expert who has served across several federal health agencies over the years, was the CDC’s deputy director from January to March.

Susan Monarez is the first director of the Centers for Disease Control and Prevention to require Senate confirmation. She's also the first director without a medical degree in more than 70 years.

In a 51–47 vote along party lines, the Senate confirmed Monarez as the director of the Centers for Disease Control and Prevention. She is the first nominee for CDC director to be required to get Senate confirmation, following a 2022 law requiring it. She is also the first person to serve in the role without a medical degree since 1953.
