This MMWR report describes results of the Massachusetts Department of Public Health surveillance initiative to collect detailed information on hepatitis C virus (HCV) cases reported during 2007-2009 among 15-24-year olds, and to examine the data for trends through 2009. The results reveal the continued increase in rates of newly reported HCV infection among this age group. Cases were reported from all areas of the state, occurred predominantly among non-Hispanic white persons, and were equally distributed among male and females.

This visual file is a set of 30 slides providing information on the epidemiology of HIV infection through 2009.

This report describes the results of the analysis of previous HIV testing patterns among adults and adolescents newly diagnosed with HIV infection, using 2006-2008 data from 18 jurisdictions that participate in HIV incidence surveillance as part of CDC’s National HIV Surveillance System. Findings indicate that among adults and adolescents for whom testing history was available, 41 percent were diagnosed with HIV at the first test and 59 percent had a negative test some time before HIV diagnosis.

In this report, the CDC used the National HIV Surveillance System data to estimate among youths, prevalence rates of diagnosed HIV infection in 2009 and the number of new infections in 2010. CDC used the 2009 and 2010 Youth Risk Behavior Surveillance System for 9th -12th grade students and the 2010 National Health Interview Survey for persons 18-24 years. Prevalence of diagnosed HIV was 69.5 per 100,000 youths at the end of 2009. Youth accounted for 12,200 (25.7 percent) new HIV infections in 2010.

Young people in the United States remain at risk for HIV infection. An estimated 56,300 Americans are infected with HIV each year. Of these, 34%, or approximately 19,000, are adolescents or young adults aged 13–29 years. Young men who have sex with men (YMSM), especially black YMSM, are at highest risk. This information sheet highlights the ongoing risk for HIV infection among YMSM and underscores the need to reach each new generation with effective HIV prevention messages and services. Schools and education agencies are important partners in this effort.

This pamphlet discusses the human papillomavirus (HPV), cervical cancer caused by HPV, testing, and available vaccines. It explains viruses, HPV, the different types of HPV, how it is transmitted, how common it is, and the risk factors for both men and women. The information sheet also discusses HPV prevention, symptoms, testing, how the virus is treated, and its relation to cervical cancer, as well as cancers of the vulva, vagina, anus, penis, and mouth and throat. Detailed information is provided about the HPV vaccines and who should be inoculated and at what ages.

This information sheet for parents discusses the need for the human papillomavirus (HPV) vaccine to protect their children from HPV infection. It explains that HPV can cause anal and oropharyngeal cancers in both women and men; cancers of the cervix, vulva, and vagina in women; and cancer of the penis in men. The information sheet notes that the virus is transmitted during sexual contact and reminds parents that the vaccine is recommended for preteen girls and boys ages 11 or 12 and can be given to older youth who have not been vaccinated.

The annual surveillance report, published by CDC's Division of HIV/AIDS Prevention (DHAP), summarizes information about diagnosed HIV infection in the United States and dependent areas. The 2011 HIV Surveillance Report marks the first time estimated numbers and rates of diagnoses of HIV infection have been included from all 50 states, the District of Columbia, and 6 U.S. dependent areas (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Republic of Palau, and the U.S. Virgin Islands).

This surveillance supplemental report complements the 2010 HIV Surveillance Report by presenting data on diagnoses of HIV infection during 2010 and persons living with a diagnosis of HIV infection at year-end 2009 for adults and adolescents aged 13 years and older residing in metropolitan statistical areas (MSAs) in the United States and Puerto Rico. The report presents the unadjusted number, estimated number, and estimated rate of diagnoses of HIV during 2010 and of persons living with a diagnosis of HIV as of December 31, 2009. Data are presented by MSA of residence at diagnosis.

This report summarizes national HPV vaccination coverage levels among adolescent girls aged 13-17 years from the 2007-2012 National Immunization Survey-Teen (NIS-Teen) and national postlicensure vaccine safety monitoring. It states that despite availability of safe and effective vaccines and ample opportunities for vaccine delivery in the health-care setting, HPV vaccination coverage among adolescent girls did not increase from 2001-2012. The report finishes by stating that an additional 53,000 cases could be prevented by increasing the 3-dose HPV vaccine coverage by 80%.
