Communicable Diseases

Communicable diseases are infectious diseases that are spread from person to person (e.g., E. coli, Salmonella, chickenpox) or from animals to people (e.g., rabies, H1N1). There are 70 communicable diseases that are reportable to the Cook County Department of Public Health (CCDPH) so we can prevent the spread. To download the CCDPH Reportable Diseases poster, please click here.

In addition, we prevent the spread of infectious diseases through disease surveillance, community education, outbreak response and by providing recommendations to control the spread of communicable diseases in suburban Cook County.

Current Topics of Interest in suburban Cook County

  • Rabies/Animal Bites
    • Rabies is transmitted through the saliva of an infected mammal, most commonly bats. Animals such as birds and amphibians (turtles, frogs, etc.) do not get or transmit rabies.
    • If you have a bat in your home or if you see a dead bat, DO NOT TOUCH IT. Call Animal Control in your area so the bat can be tested for rabies.

  • MRSA
    • MRSA stands for Methicillin-Resistant Staphylococcus aureus. S. aureus is a bacterium that is present on the skin of some people and can also be present in the nose. MRSA is the same bacterium but is resistant to some antibiotics. About 1 in 4 people have S. aureus; in those with S. aureus about 1 in 100 have MRSA.
    • Most people with MRSA in their nose do not have any symptoms. However, in some, MRSA can cause skin or soft-tissue infections. Most of these types of infections can be treated with appropriate medical care.
    • MRSA is transmitted through direct skin-to-skin contact with an infected person or through personal items such as towels. To reduce the risk of getting or spreading MRSA, take the following steps:
      • Practice good personal hygiene. Wash your hands often with soap and water or use an alcohol-based hand sanitizer.
      • Avoid sharing personal items such as clothing, towels or razors.
      • If you have MRSA, keep any open or draining wounds covered. If you are unable to keep wounds covered, avoid direct contact with others until your wound has healed.
