National Public Health Week (NPHW) is a time to recognize the contributions of public health and highlight the issues that are important to improving our nation's health. Ready. Set. Action! is the 2026 theme. As we celebrate, take a moment to recognize how public health has improved our daily lives, safeguarded our families, expanded our life spans, and strengthened our communities. This week is also a chance to honor the public health workers who show up for us every day — and to advocate for policies and practices that promote good health for all.
