Health care-Associated Hepatitis B and C Outbreaks (≥ 2 cases) Reported to the Centers for Disease Control and Prevention (CDC) 2008-2019

The tables below summarize health care-associated outbreaks of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection reported in the United States during 2008-2019. Outbreaks previously reported in 1998-2008 can be found in Thompson, et alexternal icon and Redd, et alexternal icon. Because of the long incubation period (up to 6 months) and typically asymptomatic course of acute hepatitis B and C infection, it is likely that only a fraction of such outbreaks that occurred have been detected, and reporting of outbreaks detected and investigated by state and local health departments is not required. Therefore, the numbers reported here may greatly underestimate the number of outbreak-associated cases and the number of at-risk persons notified for screening.

Practical guidance on detecting and investigating such outbreaks may be found in the Health care Investigation Guide.

Resources for prevention include updated hepatitis B immunization guidelines, and infection control guidelines and resources.

Summary

66 outbreaks (two or more cases) of viral hepatitis related to health care reported to CDC during 2008-2019; of these, 62 (94%) occurred in non-hospital settings.

Hepatitis B (total 25 outbreaks including two of both HBV and HCV, 183 outbreak-associated cases, 13,246 persons notified for screening):

  • 19 outbreaks occurred in long-term care facilities, with at least 133 outbreak-associated cases of HBV and approximately 1,679 at-risk persons notified for screening
    • 79% (15/19) of the outbreaks were associated with infection control breaks during assisted monitoring of blood glucose (AMBG)
  • 6 outbreaks occurred in other settings, one each at: an outpatient cardiology clinic, a free dental clinic in school gymnasium, an outpatient oncology clinic, a hospital surgery service, and two at pain remediation clinics (one outbreak of HBV and one with both HBV and HCV), with 50 outbreak-associated cases of HBV and 11,567 persons at-risk persons notified for screening

Hepatitis C (43 total outbreaks including two of both HBV and HCV , 328 outbreak-associated cases, >112,406 at-risk persons notified for screening):

  • 16 outbreaks occurred in outpatient or long-term care facilities (including the two outbreaks of both HBV and HCV also listed above), with 134 outbreak-associated cases of HCV and >80,293 persons notified for screening
  • 22 outbreaks occurred in hemodialysis settings, with 104 outbreak-associated cases of HCV and 3,134 persons notified for screening
  • Four outbreaks occurred because of drug diversion by HCV-infected health care providers, with at least 90 outbreak-associated cases of HCV and 28,989 persons notified for screening

Single identified cases are not included in the table and may be particularly difficult to confirm as health care-associated infection transmission events. However, although this list is not exhaustive, during 2008-2018 the following single cases were reported and confirmed as likely patient-to-patient health care-associated transmission:

1 The number of persons notified for screening is dependent upon information and resources available at the time of investigation and may underestimate the total number of individuals at risk.

2 Outbreak-associated HBV and HCV infections are defined as those with epidemiologic evidence supporting health care related transmission and include patients/residents identified with acute infection, or previously undiagnosed chronic infections with epidemiologic evidence indicating that these were likely outbreak-related incident cases that progressed from acute to chronic. Patients/residents identified as likely (previously infected) sources for transmission are not included. In the outbreak investigation setting case definitions are based on laboratory profile and clinical evidence rather than CDC surveillance case definitions which may omit asymptomatic cases.
Acute HBV is typically defined as having a positive hepatitis B surface antigen and positive IgM core antibody, or positive surface antigen and negative total core antibody (early infection). Chronic HBV is typically defined as having a positive hepatitis B surface antigen, positive total core antibody and negative IgM core antibody. There are no serologic markers to differentiate between acute and chronic HCV infection; defining an infection as possible health care transmission is dependent upon epidemiologic evidence along with a new finding of hepatitis C antibody and/or RNA positivity in a person not previously known positive (whether or not symptoms or alanine aminotransferase [ALT] elevation are present).

3 All modes of transmission are patient-to-patient unless otherwise indicated.

4 One additional health care facility outbreak was reported during 2009, in an Illinois psychiatric long term care facility with 8 outbreak-related hepatitis B cases among 180 residents screened, and an additional three cases of chronic HBV infection detected at the time of screening. The likely mode of transmission was sexual contact, though other behavioral risk factors such as illicit drug use could not be ruled out.
