The outbreak of Ebola in the Democratic Republic of Congo that killed 29 and sickened 24 more has ended, according to officials from the World Health Organization.

The last confirmed patient with Ebola was discharged June 12 after he or she no longer tested positive for the virus. Officials were unable to declare the outbreak over until now, waiting until 42 days, or two incubation periods, passed without any more people testing positive for Ebola.
