Congo's Ebola outbreak has claimed at least 2,000 lives, making it the fastest-growing on record. Government data shows 4,381 confirmed cases, with 2,011 deaths. Health authorities struggle to reach remote areas due to rebel conflict, bad roads, and work stoppages over payment issues. The outbreak, declared on May 15, likely began months earlier. It's the second-largest in history, behind the 2014-2016 West Africa outbreak. The Bundibugyo virus responsible has no approved vaccines or treatments. Clinical trials have begun in Ituri province. Aid workers say the outbreak outpaces response efforts, with many health workers on strike.
