Communicable Disease Investigation & Surveillance
It's much easier to control and prevent a disease outbreak than to treat one. The Grundy County Health Department monitors our county for possible disease trends. This is called surveillance. Surveillance sites are located throughout the county; they report the number of sick people so we can look for increased activity.
Certain illnesses are reportable. When a person contracts whooping cough, for example, GCHD works with the person, his family, and other possible contacts to limit the spread of disease. Vaccinations are offered, if appropriate, and contacts are educated about how the disease can be spread.
