The CDC is bringing back around 450 employees who were previously laid off as part of a federal workforce trimming exercise.
The decision is a partial reversal of the April announcement to cut over 10,000 jobs across health agencies to reduce government expenditure.
The reinstated staff worked in key public health divisions like HIV, viral hepatitis, STD, tuberculosis prevention, environmental health, and global health.
Their work includes areas such as air quality, toxic chemical spill response, lead-poisoning prevention, and global disease surveillance.
The original plan identified over 2,400 positions at the CDC to be cut, with layoffs being part of a federal downsizing effort begun by President Trump.
Public health advocates raised concerns over the cuts, warning of risks to community health and safety.
In response, Health Secretary Robert F. Kennedy Jr. mentioned that certain roles would be restored after the backlash.
The Department of Health and Human Services withdrew termination notices of certain impacted employees, instructing them on resuming work discussions.
Returning employees include members of the CDC's Lead Poisoning Prevention and Surveillance Branch, set to be part of a new division called the Administration for a Healthy America.
The reinstatement reflects the acknowledgement of the necessity to uphold a strong public-health infrastructure despite fiscal reform efforts.
