The death toll from the Ebola outbreak in the Democratic Republic of Congo has reached 600 as suspected infections appear in provinces that were previously unaffected. Health authorities have confirmed more than 1,700 cases and are investigating possible transmission beyond the original centre of the outbreak. Medical teams face difficult conditions, including limited infrastructure, insecurity and disputes over pay. Researchers have also begun clinical studies of potential treatments. The spread into new areas has increased concern among neighbouring countries and international health organisations, which are working to improve screening, contact tracing, vaccination and public information.
