New animal transmission caused Congo's deadliest Ebola outbreak

aljazeera.com

A new study published in Nature Medicine found that the Ebola outbreak in the Democratic Republic of Congo was caused by a new animal-to-human transmission, not variants from earlier outbreaks. The outbreak has killed over 2,000 people. The virus in eastern DRC has killed more than 2,000 of 4,449 recorded cases, making it the fastest-moving Ebola outbreak on record. It was formally declared on May 15, though genetic sequencing later revealed the virus had actually begun circulating in February. The outbreak strain was genetically distinct from previous Bundibugyo Ebola viruses seen in 2007 and 2012. The animal source has not been specified, but researchers said the Uganda outbreak was linked to the DRC outbreak. No vaccine has been developed for the rare Bundibugyo strain, and the WHO said the outbreak is on track to become the deadliest on record.
