The Ebola outbreak that struck West Africa more than three years ago left the region without protective equipment to use in the face of the disease. The World Health Organization estimated about 35 percent of people exposed to the virus were allowed to enter their houses without protective gear.

Today, there is no vaccine or cure for Ebola, the virus that caused more than 11,000 deaths in the worst-ever outbreak. While there have been at least two outbreaks since the one in 2014, those have not been as deadly or widespread as in the original West African outbreak.

On Wednesday, a U.S. company called BioProtection Systems announced that it is the first to make a mask designed to combat Ebola. The mask’s medical contact lens can filter light coming into the wearer to hide a person’s eyes. BioProtection claims the mask is 50 percent better than alternative models. The company has started selling its masks in government stocks in Africa. Other companies, such as BioSante Pharmaceuticals, are also developing potential Ebola treatments.
