National Public Health Week runs April 5–11, 2027, a seven-day look at the work that keeps whole communities healthy, from clean water to vaccines.
First Full Week of April
Every year in early April, Monday through Sunday, starting on the month’s first Monday. The 2026 week ran April 6 to 12, and the 2027 week runs April 5 to 11.
Each year’s dates are posted well ahead on APHA’s site. President Bill Clinton first proclaimed the week in 1995. The American Public Health Association, known as APHA, has organized it every April since, for more than 30 years now.
Lawmakers often weigh in. In 2026, Senator Ben Ray Luján of New Mexico introduced a resolution recognizing the week.
A 1995 Proclamation
Clinton signed the first proclamation on March 13, 1995, for a week running April 3 to 9.
Clinton’s text noted that medical technology had advanced “to a level unimaginable to the generations before.” It called immunizing people against infectious disease a vital task.
He asked “all Federal, State, and local public health agencies” to team up with private groups and schools. Their job was to promote healthy lifestyles.
APHA itself is more than 150 years old. Dr. Stephen Smith, a physician and lawyer who served on New York City’s health board, founded it in 1872.
Its history includes landmark moments. At APHA’s 1900 meeting, Walter Reed reported that mosquitoes carry yellow fever.
WHO’s creation in 1948 had strong APHA support too.
Membership kept growing. APHA had 25,100 members at its 100th anniversary in 1972 and 32,000 by its 125th in 1997.
What the Week Pushes For
APHA’s 2026 campaign line was blunt: “Good health doesn’t just happen.” The theme was “Ready. Set. Action!”
Policy runs through the message. “Good health happens when policymakers prioritize public health for all communities,” APHA said of the Senate resolution.
Georges Benjamin, APHA’s longtime CEO, thanked Luján for “continuing to be a public health champion.”
Participation is growing fast. Partners hosted 300 events in 2025, a 163% jump from the year before.
Public health’s track record is the backdrop. APHA credits more than 150 years of public health work with adding decades to American life expectancy.
Toolkits from APHA follow each year’s theme. The resources keep working after the week ends, in classrooms, clinics and health departments.
Vaccines and healthy lifestyles, both named in the 1995 text, remain central three decades later.
The association’s reach helps. Its yearly meeting draws about 12,000 public health professionals and partners.
