The WHD was first inaugurated in May 2005.
The purpose of the WHD is to promote public awareness of hypertension and to encourage citizens of all countries to prevent and control this silent killer, the modern epidemic.
The theme of World Hypertension Day 2019 is "Know your numbers"
The theme is meant to raise awareness about high blood pressure in people across the world.
