National Public Health Week

In 1995, former President William Jefferson Clinton proclaimed the first full week of April as National Public Health Week (NPHW). Each year since then, the public health community has celebrated this observance by focusing on an issue that is important to improving the public's health.

The American Public Health Association (APHA) serves as the lead organizer of NPHW and with the help of its 50,000 members and hundreds of organizational partners, educate the public, policymakers, and practitioners about the importance of public health. 

National Public Health Week 2012 will be observed April 2-8, 2012. The theme is “A Healthier America Begins Today: Join the Movement!” APHA continues to champion the creation of the healthiest nation in one generation with an emphasis on public health’s essential role in prevention. 

World Health Day

The World Health Organization was founded on April 7, 1948. Delegates at the First World Health Assembly in 1948 called for a World Health Day to be health every year to mark the anniversary of the founding. World Health Day has been held every year since 1950 and is used to draw attention to particular priorities in global health. The theme for 2012 will be "Ageing and Health."
