In Catholic tradition, patron saints are holy men and women whose lives and intercession are considered especially suited to particular needs, groups, or situations. The Church's practice of invoking saints reflects the doctrine of the Communion of Saints — the belief that the faithful departed remain united with the living in the one Body of Christ and can intercede before God on our behalf.
The designation of a patron saint for "Public Health Workers" reflects centuries of Catholic popular devotion and, in many cases, formal proclamations by popes or bishops recognizing a saint's particular connection to this intention through the circumstances of their life, death, or documented miracles.

Saint Martin de Porres is invoked as patron of public health workers. Martin de Porres was born in Lima, Peru, on December 9, 1579, the illegitimate son of a Spanish nobleman, Don Juan de Porres, and Ana Velazquez, a freed Black or Indigenous woman from Panama. His father initially refused to acknowledge him because of his dark skin, and Martin grew up in poverty with his mother and sister. Sources: https://www.usccb.org/resources/2026cal.pdf.
