    Insights

    Reporting of chronic hepatitis B (HBV) and hepatitis C (HCV) infections remains incomplete in Michigan. While recent diagnoses improved reporting, demographic variations and lack of risk factor data hinder accurate disease surveillance.

    Area of Science:

    • Hepatology
    • Public Health Surveillance
    • Infectious Diseases

    Background:

    • Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of liver cirrhosis and cancer.
    • Underreporting complicates understanding the national burden of viral hepatitis.
    • Improving national surveillance requires assessing local and state reporting completeness.

    Purpose of the Study:

    • To evaluate the completeness of chronic HBV and HCV infection reporting in Michigan.
    • To identify factors influencing reporting accuracy for viral hepatitis.

    Main Methods:

    • Partnered with Michigan Department of Community Health and an urban healthcare system.
    • Assessed reporting of chronic HBV/HCV cases from a cohort study to the state registry.
    • Analyzed completeness of case status, demographics, and risk factor information.

    Main Results:

    • 82% of chronic HBV and 65% of chronic HCV infections were reported.
    • Reporting completeness improved for recent diagnoses but remained incomplete.
    • Reporting varied by HCV patient demographics; risk factors were rarely reported.

    Conclusions:

    • Improving viral hepatitis surveillance requires efficient data transfer and better risk factor identification.
    • Collaborations using electronic health records and laboratory data can reveal reporting challenges.
    • Enhanced surveillance is crucial for preventing viral hepatitis transmission.

    Hepatitis

    Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

    Viral Hepatitis I: Introduction

    Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

    Diseases of the Liver and Gallbladder

    Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
    Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
