The eastern Congo Ebola outbreak is now the fastest-growing on record — nearly 2,000 cases and 702 deaths — and is spreading into more provinces and major cities.
Response efforts are hampered by violence, mistrust and a strike by unpaid treatment-center staff, which risks further disruption to care.
Researchers have just started a trial of two treatments (remdesivir and an experimental antibody, MBP134), but results could take months and require many patients.
