The number of newly discovered HIV cases in people aged 60 or older increased in Beijing in recent years.

Men who have sex with men remain one of the key groups in which the city is intervening to stop the spread of HIV, said an official from the city's Center for Disease Prevention and Control.

The latest statistics made public by the city's Health and Family Planning Commission show that from January to the end of June, the city reported 48 HIV cases in people 60 or older, compared with only 17 cases in 2007.
