GENEVA (AP) — The ongoing Ebola outbreak in Congo is on track to surpass the deadliest one in history that killed over 11,000 people out of more than 28,000 cases, the head of the World Health Organization said Wednesday. “At its current pace, it’s on track to eclipse the West African Ebola outbreak of 2014 to 2016,” Tedros Adhanom Ghebreyesus told reporters. The outbreak in eastern Congo , considered the fastest-growing in history, has killed over 2,000 people out of more than 4,300 cases. Some health workers have gone on strike over lack of pay. “There is a one-case scenario where this outbreak may last nine months to 12 months.”
