The Democratic Republic of Congo (DRC) has recorded 11,042 confirmed Ebola cases and 5,387 deaths, according to government data released Tuesday, Reuters reported.

The outbreak, declared in mid-May, is caused by the rare Bundibugyo species, for which there are no approved treatments or vaccines. It is the second-largest and second-deadliest outbreak on record, behind only the 2014–2016 West African outbreak. Eight of the country’s 26 provinces have been affected, and delayed detection, conflict and strained health services have accelerated the spread.
