To avert the most infections and improve health outcomes, sexually active men who have sex with men should receive an HIV test at least once a year. If positive, they should be linked to and retained in HIV medical care to achieve viral suppression. Those testing negative should be provided HIV prevention services, including pre-exposure prophylaxis (PrEP). Sexual HIV risk changes through the lifespan. CDC analyzed national data on HIV diagnoses among gay and bisexual males by age group. Among gay and bisexual males with HIV diagnosed during 2008-2016:

13- to 29-year-olds

  • Accounted for 45 percent of diagnoses
  • Diagnoses increased about 3 percent per year
  • Diagnoses were almost quadruple that of those age 50 and older

30- to 49-year-olds

  • Accounted for 43 percent of diagnoses
  • Diagnoses decreased about 4 percent per year

Age 50 and older

  • Accounted for 12 percent of diagnoses
  • Diagnoses remained stable

The analysis also found that during 2008-2015, the number of gay and bisexual men age 50 and older living with diagnosed HIV increased an average of 11 percent per year and was triple that of 13- to 29-year-old gay and bisexual males, and that racial disparities persisted. Sexually active gay and bisexual males should be tested at least once a year.

Dogs, including puppies, can spread Campylobacter to people and make people sick. Thoroughly washing hands after contact with dogs or dog poop will reduce the risk of infection. Campylobacter causes an estimated 1.3 million diarrheal illnesses in the United States annually. Epidemiologic, laboratory, and traceback evidence indicates that puppies sold through the commercial dog industry were the source of a multistate outbreak of multidrug-resistant Campylobacter infections investigated from 2017 to 2018. There were 118 ill people reported, including 29 pet store employees, from 18 states. This outbreak demonstrates that puppies can be a source of multidrug-resistant Campylobacter infections in people, warranting a closer look at the use of antibiotics in the commercial dog industry.

CDC Grand Rounds: Promoting Well-Being and Independence in Older Adults

404-639-3286

As the proportion of older adults in the U.S. continues to grow rapidly, public health can help enhance health and well-being for the aging population by promoting recommended clinical preventive services and encouraging earlier disease detection and care planning, including discussing any concerns about memory loss with a health care provider. Americans continue to live longer and the proportion of older adults in the population is projected to increase over the next few decades. Public health plays a vital role in the health promotion and well-being among this growing segment of the population. Along with the benefits of living longer comes an increase in the prevalence of chronic diseases, including Alzheimer ’s disease and other dementias. These challenges require collective action on the part of health care providers, public health practitioners, caregivers, family, and friends of older adults to maximize the health and quality of life for older adults, such as promoting available recommended clinical preventive services such as annual flu shots and cancer screening, and encouraging earlier disease detection and care planning.
