The Ebola virus has struck again just one week after the Democratic Republic of Congo’s Health Ministry reported the end of the viral outbreak.

The latest outbreak was the 10th time that Ebola has surfaced in the country.

The health minister, Dr. Oly Ilunga Kalenga, said in a statement that the authorities had notified his ministry on Saturday of 26 suspected cases of Ebola, including the 20 deaths.

Samples from six survivors were analyzed on Tuesday and four tested positive for the virus.
