The Africa Centres for Disease Control and Prevention (Africa CDC), the African Union’s peak public health agency, has confirmed a new Ebola outbreak in the Democratic Republic of Congo, with 246 suspected cases and 65 reported deaths. So far, four deaths from Ebola have been confirmed by laboratory analysis, the agency reported in a statement on Friday.

A drug has been shown to successfully prevent the deaths of two species of monkeys infected with Ebola, according to a scientific article published this Friday in the journal of the American Association for the Advancement of Science (AAAS). The antiviral, called Obeldesivir and in pill form, prevented between 80% and 100% of the deaths of 10 macaques that had been exposed to the Makona variant of the virus, which caused the deadliest outbreak to date, in 2014, in central and western Africa.
