On the occasion of the World Health Day 2017, the World Health Organization (WHO) has launched its year-long campaign under the slogan "Depression: Let's Talk". As depression is the leading cause of disability worldwide, this year's campaign aims to empower people with depression and their families to talk about it and seek help on one hand and promote realistic understanding of the nature of this illness.
You can check the campaign on the website which also has informative posters and handouts.
