Disturbing details about deliberate attacks on health workers show how important it is to come up with new measures to protect them, the UN said Friday.

According to the World Health Organization (WHO) and its #ThanksHealthHero hashtag social media campaign, more than 600 health professionals died in direct attacks in 2014, and nearly 1,000 more were injured. This data comes from just 32 countries.

Understandably, the world’s war zones have proved to be the most dangerous for health workers. But the WHO adds that life-savers have also faced attacks in combatting Ebola in Guinea and polio in Pakistan.

Talking to Daniel Johnson in Geneva are WHO's Dr Rudi Coninx and first, Erin Kenney.
