HIV Infection Among Injection-Drug Users --- 34 States, 2004--2007

In this report, the Centers for Disease Control and Prevention (CDC) analyzed data from the national notifiable disease reporting system for 2004-2007 from the 34 states with confidential name-based HIV reporting since 2003. Data represent injecting drug users (IDUs) who received a new diagnosis of HIV infection, regardless of when the infection was acquired and excluding IDUs categorized as men who have sex with men. Number and percentage of IDUs who were diagnosed with HIV were estimated by sex, age, race/ethnicity, and area of residence at the time of diagnosis.

MMWR: Evaluation of Acute Hepatitis C Infection Surveillance – United States, 2008

This report describes CDC comparison of acute hepatitis C virus (HCV) surveillance data reported in 2008 from the National Notifiable Diseases Surveillance System (NNDS) and the Emerging Infections Program (EIP), which conducts enhanced surveillance for acute hepatitis C in selected states. Results show that 26 of 120 cases reported from EIP-funded sites were missing from NNDSS. Data on race and major HCV risk factors were missing from 22 percent and 60 percent of reports in NNDSS, compared with 8 percent and 25 percent of reports in EIP, respectively.

MMWR: Racial/Ethnic Disparities Among Children with Diagnoses of Perinatal HIV Infection --- 34 States, 2004--2007

This report describes the most recent trends in diagnoses of perinatal HIV infection by race/ethnicity, by summarizing results of analyses of national surveillance data from 34 states from 2004-2007. During 2004-2007, 85 percent of diagnoses of perinatal HIV were in blacks or African Americans (69 percent) or Hispanics or Latinos (16 percent). The average annual rate of diagnoses of perinatal HIV during that time was 12.3 per 100,000 among blacks, 2.1 per 100,000 among Hispanics, and 0.5 per 100,000 among whites.

Seroprevalence of Herpes Simplex Type 2 Among Persons Aged 14-49 Years--United States, 2005-2008

The Centers for Disease Control and Prevention (CDC) analyzed serologic test results from persons aged 14-49 years who participated in the National Health and Nutrition Examination Survey (NHANES) 2005-2008, to determine whether HSV-2 seroprevalence in the United States has changed since 1999-2004. CDC also used the data to estimate HSV-2 seroprevalence by age, race/ethnicity, and reported lifetime number of sex partners. Results indicated that HSV-2 seroprevalence was 16.2 percent overall, not statistically different from that of 1999-2004, and was highest among women and non-Hispanic blacks.

Congenital Syphilis – United States, 2003-2008

This report summarizes the results of a CDC analysis of recent trends in congenital syphilis (CS) rates, using national surveillance data from the years 2003-2008. Results show that after declining for 14 years, the CS rate among infants aged <1 year increased 23 percent, from 8.2 cases per 100,000 live births in 2005 to 10.1 during 2008. The increase followed a 38 percent increase in primary and secondary syphilis rate among females aged =10 years from 2004-2007.

The data show that of 8,153 MSM interviewed and tested in the 21 MSAs participating in NHBS in 2008, HIV prevalence was 19 percent, with non-Hispanic blacks having the highest prevalence (28 percent), followed by Hispanics (18 percent), non-Hispanic whites (16 percent), and persons who were multiracial or of other race (17 percent).
