WATCH: The Battle Against Sleeping Sickness

This article is part of HuffPost’s Project Zero campaign, a yearlong series on neglected tropical diseases and efforts to fight them.

“Out of Sight” is a series of 360-degree films telling the stories of the victims and the health workers battling neglected tropical diseases in some of the most remote and underdeveloped regions of Nigeria and Congo. The series explores efforts to eliminate three of those diseases, the challenges and the progress.

Sleeping sickness, the focus of this film, was once a major cause of mortality in tropical Africa but now may be nearly eliminated, thanks to the intervention of health workers and national health programs. As many as 80 percent of the remaining cases are found in Congo, where this was filmed.

To watch this 360-degree film on your desktop, make the video player (above) fullscreen; then click and drag to change the camera angle. If viewing on a mobile device, tap and drag your finger to explore the scene.
