Jon Stewart will be on hand to help launch a publicity blitz Monday urging hundreds of thousands of regular Joes to apply for 9/11 medical funds.

There is a misconception that the 9/11 Victims Compensation Fund only covers first responders who got sick breathing toxic fumes while toiling at Ground Zero, when it is really for anyone who became ill with a 9/11-related condition while living, working or going to school in downtown Manhattan after the attacks, say TV’s former “The Daily Show” host and other 9/11 health advocates.

“Nobody owns 9/11,” Stewart said in a statement.

“Those who lived in Lower Manhattan and went to school in Lower Manhattan deserve everything that first responders get, and as an individual who lived in Lower Manhattan on 9/11, I implore everyone to get into the WTC Health program and file a claim with the VCF,” he said.

“We are all equal shareholders, no matter first responder, responder, volunteer, survivor or student.”

About 450,000 people are eligible for free lifetime medical care under the health program, but less than a quarter are enrolled. Of those enrolled, 76,050 are responders, and just 21,636 are “other survivors” who resided, worked or went to school in the Ground Zero vicinity, according to statistics compiled by the World Trade Center Health Program.

Stewart will help kick off a publicity campaign to push for more enrollment with a 6 p.m. forum at the Borough of Manhattan Community College in Lower Manhattan. Others scheduled to participate in the gathering include US Sen. Kirsten Gillibrand (D-NY), John Feal of the FealGood Foundation, Lila Nordstrom of Studentsof911.org and lawyer Michael Barasch, who has repped 9/11 victims and survivors.

The VCF was extended permanently by Congress and President Trump in July.

During the debate to permanently extend it, some sick responders appeared before Congress, including cancer-stricken NYPD Detective Luis Alvarez, who died just weeks after his appearance on the Hill with Stewart.

Barasch, whose firm Barasch & McGarry represents thousands of people exposed to 9/11 toxins during and after the terrorist attacks toppled the World Trade Center towers, noted that there were 19,000 students and 3,000 teachers and other educators who were exposed to contaminants after the horror.

One of them was BMCC accounting professor Yvonne Phang, who said she was “clueless” and didn’t “connect the two’” when she was diagnosed with breast cancer in October 2017, had a double mastectomy and underwent four months of chemo. She later found out about VCF through a friend, applied and became eligible for medical coverage and is now spreading the word to others.

BMCC was severely impacted by the terrorist attacks. The college’s Fiterman Hall was destroyed when a building in the World Trade Center crashed on the hall’s south wall. And the college’s main building on Chambers Street is just a half-mile north of where the towers fell.

When she was diagnosed with cancer, Phang had exhausted her sick leave time and was only able to stay on the payroll because other professors donated their sick leave to her.

Residents need to provide evidence to prove they spent time in the Ground Zero vicinity to obtain medical coverage.

At the forum, attendees will be urged to:
