Revision of the CDC surveillance case definition for acquired immunodeficiency syndrome

The following revised case definition for surveillance of acquired immunodeficiency syndrome (AIDS) was developed by CDC in collaboration with public health and clinical specialists. The Council of State and Territorial Epidemiologists (CTSE) has officially recommended adoption of the revised definition for national reporting of AIDS. The objectives of the revision are a) to track more effectively the sever disabling morbidity associated with infection with human immunodeficiency virus (HIV) (including HIV-1 and HIV-2); b) to simplify reporting of AIDS cases; c) to increase the sensitivity and specificity of the definition through greater diagnostic application of laboratory evidence for HIV infection; and d) to be consistent with current diagnostic practice, which in some cases includes presumptive, i.e., without confirmatory laboratory evidence, diagnosis of AIDS-indicative diseases (e.g., Pneumocystis carinii pneumonia, Karposi\ue2\u20ac\u2122s sarcoma).reported by Council of State and Territorial Epidemiologists; AIDS Program, Center for Infectious Diseases, CDC."August 14, 1987."Includes bibliographical references (p. 9s)

Laboratory methods for the diagnosis of epidemic dysentery and cholera

This manual focuses on the epidemiology of four organisms causing epidemic diarrhea and the laboratory methods used to identify them and to test their susceptibility to antimicrobial agents in the epidemic setting. The laboratory techniques and study methodology described provide accurate and useful information for the control of epidemics using a minimum of resources."Prepared by the National Center for Infectious Diseases, Centers for Disease Control and Prevention, Atlanta, Georgia, USA, in cooperation with the World Health Organization Regional Office for Africa, Harare, Zimbabwe."Prepared by Cheryl A.

Prevention of perinatal Group B streptococcal disease: revised guidelines from CDC

Group B streptococcus (GBS) remains a leading cause of serious neonatal infection despite great progress in perinatal GBS disease prevention in the 1990s. In 1996, CDC, in collaboration with other agencies, published guidelines for the prevention of perinatal group B streptococcal disease (CDC. Prevention of perinatal group B streptococcal disease: a public health perspective. MMWR 1996;45[RR-7]:1-24). Data collected after the issuance of the 1996 guidelines prompted reevaluation of prevention strategies at a meeting of clinical and public health representatives in November 2001. This report replaces CDC's 1996 guidelines. The recommendations are based on available evidence and expert opinion where sufficient evidence was lacking. Although many of the recommendations in the 2002 guidelines are the same as those in 1996, they include some key changes: * Recommendation of universal prenatal screening for vaginal and rectal GBS colonization of all pregnant women at 35-37 weeks' gestation, based on recent documentation in a large retrospective cohort study of a strong protective effect of this culture-based screening strategy relative to the risk-based strategy * Updated prophylaxis regimens for women with penicillin allergy * Detailed instruction on prenatal specimen collection and expanded methods of GBS culture processing, including instructions on antimicrobial susceptibility testing * Recommendation against routine intrapartum antibiotic prophylaxis for GBS-colonized women undergoing planned cesarean deliveries who have not begun labor or had rupture of membranes * A suggested algorithm for management of patients with threatened preterm delivery * An updated algorithm for management of newborns exposed to intrapartum antibiotic prophylaxis Although universal screening for GBS colonization is anticipated to result in further reductions in the burden of GBS disease, the need to monitor for potential adverse consequences of intrapartum antibiotic use, such as emergence of bacterial antimicrobial resistance or increased incidence or severity of non-GBS neonatal pathogens, continues, and intrapartum antibiotics are still viewed as an interim strategy until GBS vaccines achieve licensure.Stephanie Schrag, Rachel Gorwitz, Kristi Fultz-Butts, Anne Schuchat.Revision of: Prevention of perinatal group B streptococcal disease : a public health perspective.
