Older adults are increasingly acquiring HIV, but are underrepresented in prevention and treatment campaigns, which is more focused on youth, according to a study.

The study, published in The Lancet Healthy Longevity, showed that the prevalence of HIV in older adults is exceeding that of younger adults. However, prevention and treatment campaigns are not adequately targeting the particular needs of the 50+ year age group, said researchers from Wits University in South Africa who investigated HIV in older people in Kenya and South Africa.
