When to suspect Ebola
Clinical criteria for Ebola Virus Disease (EVD) includes a fever of greater than 101.5 degrees Fahrenheit, and additional symptoms such as severe headache, muscle pain, vomiting, diarrhea, abdominal pain, or unexplained hemorrhage.
Countries with confirmed EVD transmission
Patients who report residence in, or travel to, an area where EVD transmission is active should be examined if they present with other clinical criteria.
Epidemiologic risk factors
Consider epidemiologic risk factors such as contact with blood or other body fluids or human remains of a patient known to have or suspected to have EVD or direct handling of bats or non-human primates from disease-endemic areas.
High risk exposures
High risk exposures include any of the following: percutaneous (e.g., needle stick) or mucous membrane exposure to blood or body fluids of EVD patient; direct skin contact with, or exposure to blood or body fluids of an EVD patient without appropriate personal protective equipment (PPE); processing blood or body fluids of a confirmed EVD patient without appropriate PPE or standard biosafety precautions; direct contact with a dead body without appropriate PPE in a country where an EVD outbreak is occurring.
Low risk exposures
A low risk exposure includes any of the following: household contact with an EVD patient and having direct brief contact (e.g., shaking hands) with an EVD patient while not wearing recommended personal protective equipment.
What is considered close contact?
Close contact with EVD patients in health care facilities or community settings. Close contact is defined as being within approximately 3 feet (1 meter) of an EVD patient or within the patient’s room or care area for a prolonged period of time (e.g., health care personnel, household members) while not wearing recommended personal protective equipment (i.e., standard, droplet, and contact precautions).
CDC Contact Information
Clinicians evaluating a patient under investigation should contact their local or state health departments. Health departments should contact CDC EOC (770)488-7100.
