Tuesday officially marks 100 days since President Donald Trump took office. In that time, he has drastically attempted to reshape the federal government through mass layoffs and spending cuts.

One such change has had far-reaching implications for the city’s health department.

The Trump administration last month stripped the department of $100 million in infectious disease prevention funds.

Now, local health officials are warning this will greatly impact the city’s ability to protect New Yorkers against future illnesses, including vaccine-preventable diseases like measles and Hepatitis A.

This all comes as measles cases have been on the rise across the country, and Health Secretary Robert F. Kennedy Jr. has been inconsistent in his support for the MMR vaccine.

Dr. Michelle Morse, interim health commissioner and chief medical officer at New York City’s Department of Health and Mental Hygiene, joined NY1 political anchor Errol Louis on “Inside City Hall” Tuesday to talk more.

“Local public health is, unfortunately, in crisis in many ways,” Morse said. “These funds that are essential to our core public health services in New York City included things like us being able to staff our public health lab.”
