How Ebola is Spread

How Ebola is Spread

There is no evidence that Ebola is spread by coughing or sneezing. Ebola is transmitted through direct contact with the blood or body fluids of a person who is sick with Ebola; the virus is not transmitted through the air (like measles virus).

Surveillance and Data Collection

Surveillance and Data Collection

Monitoring Disease Reports to Verify Diagnosis and Locate Areas where Outbreaks are Especially Intense

In close collaboration with our community partners (clinics, hospitals, health care providers) and the wider community, the staff of the Epidemiology and Communicable Disease Program works  to perform case investigations and contact tracing on reportable communicable disease cases. Program staff are especially interested in monitoring the frequency and pattern of health events through hospitalizations and deaths that occur as the result of outbreaks of infectious diseases such as West Nile Virus, Influenza or Hepatitis.

The surveillance and data collection function of the program is greatly assisted by the Illinois law that mandates reporting by health care providers, clinics and hospitals of any suspected or confirmed case of some 39 diseases.  The reportable diseases are divided into three categories and providers have between three hours and 7 days to make a report to the health department.

Health Data Analysis and Reporting

Health Data Analysis and Reporting

Analyzing and Interpreting Health Related Data

The Epidemiology and Communicable Disease Program is continuously working with area medical providers to update them on ongoing disease trends as revealed by the data that the program is constantly collecting. The program also helps county health care providers by making available the most current information on the testing, treatment, and prevention of communicable disease. 

The analytic and statistical skills of program staff are also at the disposal of the county whenever the community needs to draw up a broad based survey of health status for planning purposes. Both the 2007 Community Health Needs Assessment and Plan and the 2010-2015 Will County Community Assessment and Strategic Plan benefited from the involvement of Epidemiology and Communicable Disease data staff. In the case of the Community Assessment and Strategic Plan, it was the health department epidemiologist who was given the task of consolidating all the health related data collected by the Community Health Status Assessment Committee and reporting the results to the Steering Committee of the Mobilizing for Action through Planning and Partnership Program (MAPP). MAPP is the process that the county adopted for developing a strategic plan for improving health care and health outcomes. At present, the program is actively engaged in supporting the work of all the MAPP action committees.  

Epidemiology and Communicable Disease

Epidemiology and Communicable Disease

Epidemiology can be considered the fundamental building block of public health since it is the study of the patterns, causes and effects of disease conditions in specific populations. This is accomplished through the operation of public health surveillance, field investigations, health assessments and epidemiological studies.
