Communicable Disease Surveillance & Epidemiology
The Office of Communicable Disease Surveillance & Epidemiology (OCDSE) is responsible for reducing the incidence of communicable disease in the City of Cleveland through prevention, surveillance, and outbreak control.
What is a communicable disease?
A communicable, or infectious, disease is an illness spread by coming in contact with an infected someone or something. Bacteria, viruses, and parasites are the most common organisms causing communicable disease. These illnesses can be passed from person (or animal) to person through direct contact with body fluids, ingesting contaminated food or water, breathing contaminated air, or by the bite of an infected animal.
What diseases are reported?
In Ohio, there are more than 90 reportable illnesses, such as salmonellosis, legionella, HIV, and others. View the entire list of reportable diseases in Ohio here. To report a disease please fill out the form below and send it to the contact information below. Ohio Confidential Reportable Disease Form.
Who reports communicable diseases?
According to the Ohio Administrative Code, section 3701-3, all laboratories are required to report all positive lab results. Physicians and other health professional are required to report all positive and suspect cases. Reports are made to the local health district where the patient lives. All information reported is kept confidential.
What information does the health department collect and why?
Specific information regarding the history of disease, such as symptom onset, treatment and recent activity is helpful to the disease investigator in understanding disease impact to the patient and to the community. Analysis of collected information can aide in identifying links and trends between disease outbreaks and sources of infection. Investigations provide ideal opportunities for public health experts to educate those infected and those at-risk for illness on disease transmission and prevention.
