Staying safe from Ebola

Ebola Facts

What is Ebola virus?

Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, is a severe, often fatal illness in humans. There are five types of Ebola virus. Four of them cause the disease in humans. The first EVD outbreaks occurred in remote villages in Central Africa, near tropical rainforests, but the most recent outbreak in West Africa has involved major urban as well as rural areas. Ebola gets its name from the Ebola River, which is near one of the villages in the Democratic Republic of Congo where the disease first appeared.

How does Ebola virus kill people?

Ebola is a rare but deadly virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes levels of blood-clotting cells to drop. This leads to severe, uncontrollable bleeding. The disease, also known as Ebola hemorrhagic fever or Ebola virus, kills up to 90% of people who are infected.

How do people get Ebola?

Humans can be infected by other humans if they come in contact with body fluids from an infected person or contaminated objects from infected persons. Humans can also be exposed to the virus, for example, by butchering infected animals.

What are the symptoms?

Early on, Ebola can feel like the flu or other illnesses. Typically, symptoms appear 8-10 days after exposure to the virus, but the incubation period can span two to 21 days. Symptoms typically include weakness, fever, aches, diarrhea, vomiting and stomach pain. Additional experiences include rash, red eyes, chest pain, throat soreness, difficulty breathing or swallowing and bleeding (including internal).

How can you prevent Ebola?

There’s no vaccine to prevent Ebola. The best way to avoid catching the disease is by not traveling to areas where the virus is found. Health care workers can prevent infection by wearing masks, gloves, and goggles whenever they come into contact with people who may have Ebola.
