April 7th of each year marks the celebration of World Health Day. From its inception at the First Health Assembly in 1948 and since taking effect in 1950, the celebration has aimed to create awareness of a specific health theme to highlight a priority area of concern for the World Health Organization. To raise awareness of this year's theme - building a fairer, healthier world for everyone - Elsevier presents a curated list of free access journal articles and book chapters.
