MMWR: Case Definitions for Infectious Conditions Under Public Health Surveillance

This report provides updated uniform criteria for use by public health professionals when reporting the nationally notifiable infectious diseases listed in Part One of this report. A revision date is included for case definitions that have been revised. The case definitions for some infectious conditions not designated as nationally notifiable are included in Part Two of this report.

MMWR: Nucleic Acid Amplification Tests for Tuberculosis

This report summarizes potential uses of nucleic acid amplification (NAA) tests such as the Amplified Mycobacterium Tuberculosis Direct Test (MTD) for TB diagnosis and provides interim guidelines for the use of such tests. The report lists the current NAA tests, their FDA approved uses, their non-approved indications also known as off-label uses, limitations, and cautions.

MMWR: Outbreak of Multidrug - Resistant Tuberculosis at a Hospital - New York City, 1991.

This report summarizes an epidemiologic investigation of TB by hospital infection control, infectious disease, and employee services staff at a New York hospital. It presents information on 32 inpatients, diagnosed during January 1991 to March 1992 with multidrug-resistant Mycobacterium TB (MDR-TB). Of this group, 91 percent died; all were seropositive for HIV. The report also includes information provided by 21 health care workers (HCWs) regularly assigned to the HIV inpatient unit.

MMWR: Notice to Readers: Use of Short-Course Tuberculosis Preventive Therapy Regimens in HIV-Seronegative Persons

This report in the form of a notice to readers states that CDC in conjunction with the American Thoracic Society expects to issue new guidelines on screening and preventive therapy for TB that will include a recommendation on the use of the two-month regimen of daily rifampin and pyrazinamide (2RZ) as an alternative to 12-month isoniazid for prevention of TB in HIV-negative persons for whom preventive therapy is indicated. A comparative trial of the 2RZ regimen in HIV-negative persons has not been conducted.

MMWR: Prevention of Hepatitis A Through Active or Passive Immunization: Recommendations of the Advisory Committee on Immunization Practices (ACIP)

This report updates CDC's Advisory Committee on Immunization Practices' (ACIP) 1996 recommendations on the prevention of hepatitis A through immunization (MMWR 1996;45[RR-15].) and includes (1) new data about the epidemiology of hepatitis A; (2) recent findings about the effectiveness of community-based hepatitis A vaccination programs; and (3) recommendations for the routine vaccination of children in states, counties, and communities with rates that are twice the 1987-1997 national average or greater and consideration of routine vaccination of children in states, counties, and communities wi

Global AIDS Progarm (GAP)

This information sheet describes HHS/CDC's Global AIDS Program (GAP). Under he direction of the U.S. Global AIDS Coordinator’s Office, the CDC Global AIDS Program (GAP) is a partner in the unified U.S. Government (USG) effort to implement the President’s Emergency Plan for IDS Relief (the Emergency Plan).

Fighting A Deadly Fungus: A New Strategy to Reduce Deaths Due to Cryptococcus

This information sheet points out that the fungus Cryptococcus is the most common cause of meningitis in sub-Saharan Africa, and is a leading cause of death among people with HIV. Although it is not possible to prevent the initial infection with Cryptococcus, screening for cryptococcal antigen can detect disease before meningitis develops so treatment can begin and prevent death. A rapid, point-of-care dipstick test is now available for use in screening.

Estimates of New HIV Infections in the United States, 2006 - 2009

This information sheet presents new estimates of the annual number of new HIV infections (HIV incidence) in the United States released by CDC in August 2011. The estimates, for 2006 through 2009, are the first multi-year estimates using CDC’s national HIV incidence surveillance methodology, which is based on direct measurement of new HIV infections using a laboratory test (the BED HIV-1 Capture Enzyme Immunoassay) that can classify new diagnoses as either recent or long-standing HIV infections.

New HIV Infections in the United States, 2006 - 2009

This information sheet presents the latest estimates of new HIV infections (HIV incidence) in the United States released by CDC. These estimates are included in the CDC report, "Estimated HIV Incidence among Adults and Adolescents in the United States 2007-2010," which updates previously published estimates for 2007 through 2009. The new estimates indicate two trends: early signs of a decrease in new HIV infections among black women and an increase in new infections among young gay and bisexual men.

Locations and Reasons for Initial Testing for Hepatitis C Infection — Chronic Hepatitis Cohort Study, United States, 2006-2010

This report presents results of a survey to understand where and why individuals with chronic hepatitis C virus (HCV) infection got their intial testing. An analysis of 2006–2010 survey results from 4,689 participants in the Chronic Hepatitis Cohort Study indicated that a substantial proportion of HCV-infected patients were tested only after clinical indications that their infection had progressed and became symptomatic.
