Textbook Question
Chapter 39, Problem 1CA
During a 3-month period, acute hepatitis B virus (HBV) infection was diagnosed in 9 residents of a nursing home. Serological testing of all residents revealed that 9 people had acute HBV infection, 2 had chronic infection, 5 had antibodies to HBV, and 58 were susceptible. Medical charts of residents were reviewed for history of medications and use of ancillary medical services. Infection control practices at the nursing home were assessed through interviews with personnel and direct observations of nursing procedures. A summary of the medical charts is shown below.
*A case patient has hepatitis B.
Susceptible residents live in the nursing home but do not have hepatitis B.
- What is the usual method of transmission for hepatitis B?
- What is the probable source of infection in hospitals?
- How was this infection transmitted?
