TORONTO -- The coronavirus pandemic has prompted an all-hands-on-deck approach from health-care workers around the world, and that has pushed some celebrities and notable public figures with medical backgrounds to step up and heed the urgent calls to help out.

In Canada, former federal health minister and Independent MP Jane Philpott returned to a familiar place, the Markham Stouffville Hospital in Markham, Ont., where she worked for nearly two decades as a family physician.

Dr. Philpott started working at the hospital’s COVID-19 Assessment Centre in mid-March.

Philpott is scheduled to begin new roles this July at Queen’s University in Kingston, Ont., as the dean of the faculty of health sciences and director of the school of medicine.

Irish Prime Minister Leo Varadkar left his seven-year career as a doctor in 2013 to become a politician.

In March, he reverted to his medical roots and re-registered as a doctor with the country’s Health Service Executive.

Varadkar, who resigned as Taoiseach, or prime minister, in February and who is currently serving as a caretaker leader, is carrying out phone assessments to help free up other hospital staff, according to reports by Irish state broadcaster, RTE.

Dr. Bhasha Mukherjee is best known as the 24-year-old model and actress who was crowned Miss England 2019.

After winning the beauty queen title last August, Mukherjee put her junior doctor career at the Pilgrim Hospital in the town of Boston, England, on hold and went overseas to India to begin working as an ambassador for several charities.

But in early March, after several hospital colleagues began reaching out to her about the coronavirus outbreak, Mukherjee decided to come home and help out.

She’s undergoing a two-week quarantine before she can return to work at the hospital.

American actress Jennifer Stone, who is best known for playing Harper Finkle on the Disney Channel series “Wizards of Waverly Place,” is also taking on a new role – this time as a registered nurse.

The 27-year-old announced she was “ready to join” health-care workers in the fight against the COVID-19 pandemic in a post she shared to Instagram on April 8, the same day people online were celebrating World Health Day.
