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.
The countries of Guinea, Sierra Leone, and Liberia continue to experience an outbreak of Ebola, with a total of 7,157 cases as of October 2, 2014. Nigeria and Senegal have not reported any new cases since September 5, 2014 and August 29, 2014, respectively.
On September 30, 2014, CDC confirmed the first travel-associated case of Ebola to be diagnosed in the United States. The CDC is conducting a thorough contact investigation of people who had close contact with the confirmed case. Close contacts will be monitored for 21 days (the maximum time frame for symptoms of Ebola to develop after being exposed) to prevent any disease spread. For up-to-date information on the outbreak situation, please visit the CDC Ebola Outbreak webpage.
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.
