Confirmed Ebola cases nearly double in two days in DR Congo

The confirmed cases of Ebola have nearly doubled in two days in eastern Democratic Republic of the Congo (DRC).

Congolese authorities say the number of confirmed cases in DRC reached 225 on Friday, nearly double the figure of 121 reported two days earlier.

The outbreak is caused by the Bundibugyo virus, a rare and severe form of Ebola for which there is no approved vaccine or treatment.

The WHO has declared the outbreak a global health emergency, its highest level of alarm, and the medical NGO Doctors Without Borders, known by its French initials MSF, calls it one of the fastest-spreading Ebola outbreaks ever recorded.

Authorities have also recorded 1,028 suspected cases and more than 220 suspected deaths in DRC, while the disease has crossed into neighbouring Uganda, which has recorded nine confirmed cases and one death.

Ebola was first identified in this part of central Africa in 1976; this is the DRC’s 17th outbreak.

Bundibugyo is one of three virus types behind most major epidemics; the deadliest, the Zaire Ebola virus, drove the 2014–2016 West Africa outbreak, the largest on record, with more than 28,000 cases.

“Nobody knows the true scale and severity of this outbreak,” MSF said, warning that the response has not kept pace.

The WHO has cautioned that the death rate could reach 30 to 50 percent – the range seen in the previous two Bundibugyo outbreaks – though the rate among confirmed cases so far has been lower.

Al Jazeera’s Alain Uaykani, reporting from the eastern Congolese city of Goma on Saturday, said DRC’s health ministry had expanded testing, contact tracing and monitoring, uncovering infections that might otherwise go unrecorded.
