Reporting of Acute Hepatitis C Cases through NNDSS

Health-care providers, hospitals, and laboratories are required to send reports of cases of HCV infection to state and local health departments that include them within their jurisdiction. Reports meeting the Council of State and Territorial Epidemiologists (CSTE) and CDC case definition for acute hepatitis C* are entered into each state's notifiable disease surveillance system. States voluntarily transmit case reports to CDC on a weekly basis via the National Electronic Telecommunications System for Surveillance (NETSS). NETSS is a system of computerized record formats used to transmit NNDSS data from health departments to CDC. The NETSS case reporting form includes data on demographics (e.g., age, date of birth, sex, race, and ethnicity), clinical information (e.g., date of onset, date of diagnosis, jaundice, hospitalization, and death), and risk factor exposures occurring 6 weeks to 6 months before illness onset (e.g., injection-drug use, sexual/household contact with a person with hepatitis, blood transfusion with dates of transfusion, dialysis, needle stick, tattoo, surgery, acupuncture, and being a health-care worker who has contact with human blood). Laboratory results are not transmitted to CDC because the electronic infrastructure in NETSS does not include fields for laboratory findings.
