Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly.But it can get worse and cause life-threatening symptoms (症状), such as bleeding and trouble breathing.

When an outbreak happens because of a virus, more people could get sick because there is a lot of that virus around.
