Since the Trump Administration began, changes have occurred with information available on the CDC website.
The heading on the CDC home page is as follows:
"CDC’s website is being modified to comply with President Trump’s Executive Orders."
Trusted medical information can be found at alternative sites on many topics where the CDC information is no longer available or has been modified.
Consider searching for medical information from professional medical associations such as
The American Academy of Pediatrics
State and Local Departments of Health in Illinois
