Ebola Virus Disease

The first case of Ebola Virus Disease (EVD) diagnosed in the United States was confirmed on September 30, 2014 in Dallas, Texas. The risk of an Ebola outbreak in the United States remains low. Orange County Health Care Agency is working with community partners, including healthcare facilities, to assure that our community is prepared to safely care for and respond to a suspect case. Health care providers should remember to obtain a travel history for any patients with febrile illness, and be familiar with Ebola's clinical presentation and infection control requirements. See Provider Notice for more information. 

What is Ebola?

Ebola is a virus that has caused recent disease outbreaks in West Africa. A Person Under Investigation (PUI) has consistent symptoms and risk factors as follows:

  • Fever greater than 101.5 degrees Fahrenheit, and additional symptoms such as severe headache, muscle pain, vomiting, diarrhea, abdominal pain, or unexplained hemorrhage AND
  • Risk factors within the past 21 days before the onset of symptoms, such as contact with blood or other body fluids or human remains of a patient known to have or suspected to have Ebola; residence in—or travel to—an area where Ebola transmission is active; or direct handling of bats or non-human primates from disease-endemic areas.

How does Ebola spread?

Ebola spreads from person-to-person by direct contact with a patient’s body fluids, like saliva, blood, vomit, urine, feces, and sweat. The virus gets into the body through broken skin or mucous membranes (spongy skin like the kind you find in your nose or mouth). Ebola can also be spread by infected objects, like needles, that have been tainted with body fluids. Ebola can also spread after death, when preparing the patient’s body for burial. Ebola can’t spread through the air, in food, or water. It takes 8–10 days for most people to get symptoms, but it can range from 2–21 days. Patients can spread the virus while they have a fever or other symptoms. People who don’t have symptoms can’t spread Ebola.

  • Headache
