The World Health Organization (WHO) has officially declared a new Ebola outbreak in the Democratic Republic of Congo and Uganda to be a “public health emergency of international concern” on Sunday.

The Director-General of WHO confirmed the updated status of the outbreak saying: “after having consulted the States Parties where the event is known to be currently occurring, is hereby determining that the Ebola disease caused by Bundibugyo virus in the Democratic Republic of the Congo and Uganda constitutes a public health emergency of international concern (PHEIC), in a statement on its website.

Director-General Ghebreyesus, however, noted that the outbreak “does not meet the criteria of pandemic emergency, as defined in the IHR”.

The outbreak was first reported in the DRC’s eastern Ituri province on Friday and there are already hundreds of suspected cases, including one that crossed the border into Uganda. The latest strain of the virus has no vaccine either, according to the Africa Centres for Disease Control and Prevention, or Africa CDC, according to NPR news

Ebola is transmitted through blood and other bodily fluid as well as contaminated surfaces. Symptoms include fever, body pain, weakness, vomiting “and, in some cases, bleeding,” according to the WHO.
