An outbreak of Ebola that began in the Democratic Republic of Congo has killed more than 1,500 people, according to health authorities. More than 3,400 people have been infected since late April, making this outbreak the third-largest on record. Neighboring Uganda, which saw 20 infections and two deaths, declared itself free of Ebola in late July.
First identified in 1976, Ebola, which is considered a hemorrhagic fever virus, can result in internal bleeding and cause damage to tissues and inflammation all over the body, and ultimately death, according to Johns Hopkins Medicine.
In past outbreaks, health authorities have tried to contain the spread of Ebola by isolating those infected, monitoring anyone who has been in contact with them, and safely burying the dead. Contact tracing has been challenging during this outbreak, as many people who recently died from Ebola had not visited a health care facility or received care. This was “the most alarming finding” of the current outbreak, said Chikwe Ihekweazu, executive director of the World Health Organization’s Health Emergencies Programme, according to a July statement. Ihekweazu explained that “80% of new cases are outside our contact lists,” which has made it challenging to trace and interrupt the paths of disease transmission.
What has further complicated efforts is that there isn’t a vaccine or specific course of treatment for Bundibugyo currently, the species of Ebola driving this outbreak which has a fatality rate ranging from 30 to 50%, according to the WHO. Four vaccines are being developed and a human trial for one of those started in Oxford, United Kingdom, this month.
The WHO has noted that this outbreak is the fastest growing one in history.
“We need the world to come together, not just out of charity or out of support for the DRC, but in our own enlightened best interest,” Ihekweazu said. “The more we do right now, the better placed we will be in the future.”

The largest Ebola outbreak on record began over 12 years ago in Guinea. It then tore through Sierra Leone and Liberia, and spread to Mali, Senegal, Nigeria and parts of the U.S. and Europe. By the time it ended in 2016, it had infected more than 28,600 people and taken more than 11,000 lives.
