There are now 1,003 confirmed Ebola cases in eastern Congo, including 254 deaths, and contact tracing remains a challenge.

100 people have recovered, and 365 patients are in hospitals or isolation, the Ministry of Health said.

The Ebola outbreak was very bad in its first month, caused by a rare virus with no vaccine or treatment.

Contact tracing is still a key issue with only 55% coverage, the ministry said.

To control the outbreak, officials need to know the first case, but they are not sure when it started.

Aid cuts are affecting the Ebola response.

Officials have not found patient zero and have not traced over 35,000 contacts.

Violence from rebels is making it hard to reach many villages and people are fleeing their homes.

The disease is still spreading faster than response efforts, and its true scale is unknown.

The outbreak could surpass the one that killed over 11,000 people in West Africa from 2014 to 2016.

At a displacement camp, 10 people died last week in unusual circumstances, raising fears of an outbreak.

There have been no confirmed Ebola cases at the camp, but the death rate is unprecedented.

At least two million displaced people live in areas at risk of Ebola in Congo.

Aid cuts, rebels, and anger are complicating the Ebola response.

Uganda has closed its border with Congo due to the Ebola outbreak.

The World Cup is increasing infection risk, and some cities are taking action.

The UN refugee agency is concerned about the spread of the virus to displaced communities.

A disease outbreak at a displacement site would be a catastrophe due to poor living conditions.

Nearly a fifth of confirmed Ebola cases are children, according to UNICEF.
