April 7 marks the anniversary of the founding of the World Health Organization in 1948, and this date was chosen for World Health Day, first observed in 1950. Every year since, WHO has spotlighted a different theme reflecting an urgent global health priority — from combating communicable and non-communicable diseases to advancing universal health coverage, maternal and child health, and mental health. The day aims to mobilize governments, health institutions, and civil society around a specific health issue, raise public awareness of prevention and primary care, and advocate for policies ensuring everyone has access to quality health services regardless of where they live or their economic status, in line with WHO's founding principle of "health for all." Ministries of health, hospitals, and NGOs worldwide mark the day with free health checkups, vaccination drives, and awareness seminars, while WHO releases reports and global media campaigns highlighting the year's theme and encouraging individuals to take practical steps to improve their own health and that of their communities.
