WEST CENTRAL MICHIGAN — In response to an increasing number of questions and concerns, along with misinformation around case investigation and contact tracing, District Health Department No. 10 seeks to educate the public on these long-standing public health tools used to reduce and contain the spread of infectious disease throughout history.
According to Michigan’s Public Health Code (Act 368 of 1978), local public health is charged with communicable disease case investigation. Contact tracing is a well-tested tool in case investigation that epidemiologists have used to track and slow the spread of disease since 1813. Since then, contact tracing has been successfully used to contain communicable disease such as tuberculosis, HIV, sexually transmitted diseases, pertussis, and Ebola.
