According to the center, there were around 1.1 million registered cases of HIV in late June 2017, with half a million new cases registered in the past five years.
The data excludes Russians who have undergone anonymous testing, and foreign citizens.
“The outlook for the development of the situation remains unfavorable,” the Federal Center for Fighting AIDS was cited as saying.
In the past two years, roughly half of new HIV cases were due to unprotected sexual contact and a slightly lower number, 47 percent, through intravenous drug injections, the center said.
