World Health Day is celebrated each year on April 7 to raise awareness about significant health topics affecting people globally. Established to commemorate the founding of the World Health Organization (WHO) in 1948, this day serves as a platform to highlight critical health issues such as mental health, maternal and child health, and disease prevention. The theme for 2026 is 'Together for health. Stand with science,' which emphasizes the importance of scientific collaboration in safeguarding the health of people, animals, plants, and the planet. The WHO encourages governments and institutions to invest in science and integrate evidence-based decision-making in health, climate, and environmental policies. By focusing on vital health topics, World Health Day aims to advocate for improved health outcomes, particularly for vulnerable populations, and urges policymakers to prioritize health issues.
