is the study of the distribution and determinants of disease in a population. Public health epidemiologists monitor the health and illness of a population, investigate the factors that affect the community's health, and recommend interventions to reduce the risk of disease. Epidemiology is practiced in health departments daily and involves principles of surveillance, investigation, laboratory testing, data management and communication.

What is Ebola?
Ebola hemorrhagic fever is one of several Viral Hemorrhagic Fevers. It a rare and deadly disease caused by one of the Ebola virus strains. People who become infected typically develop fever, headache, weakness, joint and muscle aches, diarrhea, vomiting, stomach pain, and loss of appetite. Some people may also begin to hemorrhage (bleed) inside and outside of the body. It is spread by direct contact (through broken skin or mucous membranes) with an infected person’s blood or body fluids, such as urine, saliva, feces, vomit, and semen. It is also spread through contact with objects (like needles) that have been contaminated with infected secretions. For more information, see the CDC Ebola fact sheet.
Risk in the U.S.
Transmission of the virus requires direct contact with an infected person’s blood or body fluids or contact with objects contaminated with infected secretions. Therefore, there is no significant risk for widespread transmission in the U.S.

CDC encourages all U.S. healthcare providers to
Travelers returning from countries affected by the outbreak should monitor their health for 21 days after their return.
