By Andrea Shalal, Leah Douglas, Ahmed Aboulenein and Ted Hesson WASHINGTON (Reuters) -Almost half of the probationary workers at the U.S. Centers for Disease Control and Prevention and others at the National Institutes of Health are being forced out as President Donald Trump overhauls government agencies,

Department of Health and Human Services officials expected most of the agency’s roughly 5,200 probationary employees to be fired.

The United States Centers for Disease Control and Prevention is losing about 10% of its staff as the Trump administration moves ahead with plans to shrink the nation's federal workforce.
