The Advisory Committee on Immunization Practices recommends that susceptible people traveling to developing countries receive hepatitis A vaccine or immune globulin prior to departure. Until 2009, the recommendations did not address non-traveling family members or other close contacts of international adoptees. We report an outbreak of hepatitis A in 2008 that occurred in Maine. Eight members of an extended family developed hepatitis A following the arrival of an asymptomatic infant from Ethiopia who was brought to the United States by an adoption agency. Two children in the family attended an elementary school where five additional cases of hepatitis A were subsequently identified. Only three (1%) of 208 students at the school had previously been immunized against hepatitis A. This outbreak highlights the need to immunize household members and other close contacts of families adopting children from countries where hepatitis A is endemic, as well as all children at one year of age.

Background:The results of studies on the relationship between cancer and COVID-19 have been conflicting and therefore further studies are needed. We aimed to examine the incidence of COVID-19 among patients at one of the largest oncology departments in Sweden, and to evaluate and identify risk factors for poor outcomes, hospital care and death, associated with COVID-19 among cancer patients. Material and methods: This retrospective study included cancer patients at a single center who tested positive for SARS-CoV-2 by PCR either in hospital, primary health care center or commercial laboratory between 1 March and 14 August 2020. Clinical and demographic data were collected from the medical records. Logistic regression analysis was used to identify variables that associated the primary outcomes of need for hospital care and death within 30 days of positive test.
