Anaplasma phagocytophilum Transmitted Through Blood Transfusion --- Minnesota, 2007
Infected blacklegged ticks (Ixodes spp.) typically transmit Anaplasma phagocytophilum to humans.

 

Anaplasma phagocytophilum Transmitted Through Blood Transfusion
Minnesota, 2007

Anaplasma phagocytophilum causes anaplasmosis, a tickborne rickettsial disease. In November 2007, the Minnesota Department of Health was contacted about an A. phagocytophilum infection in a patient who had undergone multiple blood transfusions. This is the first published report in which transfusion transmission of A. phagocytophilum was confirmed by testing of the recipient and a donor. Although reliable evidence of transmission was provided, no cost-effective method for screening blood donors for A. phagocytophilum exists.

MMWR Recommendations and Reports

September 19, 2008 / Vol. 57 / No. RR–8
Recommendations for Identification and Public Health Management of Persons with Chronic Hepatitis B Virus Infection

Serologic testing for hepatitis B surface antigen (HBsAg) is the primary way to identify persons with chronic hepatitis B virus (HBV) infection. Testing has been recommended previously for pregnant women, infants born to HBsAg-positive mothers, household contacts and sex partners of HBV-infected persons, persons born in countries with HBsAg prevalence of >8%, persons who are the source of blood or body fluid exposures that might warrant postexposure prophylaxis (e.g., needlestick injury to a healthcare worker or sexual assault), and persons infected with human immunodeficiency virus. This report updates and expands previous CDC guidelines for HBsAg testing and includes new recommendations for public health evaluation and management for chronically infected persons and their contacts. Routine testing for HBsAg now is recommended for additional populations with HBsAg prevalence of >2%: persons born in geographic regions with HBsAg prevalence of >2%, men who have sex with men, and injection-drug users. Implementation of these recommendations will require expertise and resources to integrate HBsAg screening in prevention and care settings serving populations recommended for HBsAg testing. This report is intended to serve as a resource for public health officials, organizations, and health-care professionals involved in the development, delivery, and evaluation of prevention and clinical services.

MMWR Surveillance Summaries

October 3, 2008 / Vol. 57 / No. SS–10
Surveillance for Lyme Disease
United States, 1992–2006

Lyme disease is the most commonly reported vectorborne illness in the United States. The geographic distribution of cases is highly focused, with the majority of reported cases occurring in the northeastern and north-central states. During 1992–2006, a total of 248,074 cases of Lyme disease were reported to CDC; the number of reported cases more than doubled during this 15-year period. A disproportionate increasing trend was observed in children and young males compared with other demographic groups. The results presented in this report underscore the need for tick avoidance and early treatment interventions. Public health practitioners can use the data presented in this report to target prevention campaigns to populations with increasing incidence (i.e., children and young males).
