HIV diagnoses on the rise among older people in Europe

 Just over one in six people diagnosed with HIV in Europe between 2004 and 2015 was over 50 years of age, and new diagnoses in older people increased in 16 European countries across the same period, a study published today in The Lancet HIV shows, Aidsmap reports.

The study found that older people (people aged 50 or older) were more likely than younger people (aged 15 to 49 years) to be diagnosed with advanced HIV disease, and acquire HIV through heterosexual sexual contact. Older people diagnosed with HIV were less likely to be migrants.

Although the rate of new diagnoses in older people is less than a quarter of the rate in people aged under 50, between 2004 and 2015, the rate of diagnosis in older people increased in 16 countries.

At the time of HIV diagnosis, 39% of people over 50 had a CD4 cell count below 350 cells/mm3, indicating late diagnosis. Of these, almost three-quarters were diagnosed with a CD4 cell count below 200 cells/ mm3, indicating advanced HIV disease and a high risk of illness or death. In comparison, 26% of people under the age of 50 were diagnosed with a CD4 count below 350 cells/mm3, of whom just over half had a CD4 cell count below 200 cells/mm3.

The study authors warn that health care workers need to consider the possibility of HIV infection in older people. Health care providers should also acknowledge that older people are sexually active but less likely to use condoms.

Older people may not have accurate information about HIV transmission or the risk of exposure, and may not consider themselves to be at risk.

“We need to make both healthcare workers and the general population aware of this issue to reduce stigma and inform people about HIV risks and prevention methods,” said study author Dr Lara Tavoschi, of the European Centre for Disease Prevention and Control, Sweden.
