The Siberian cities of Kemerovo, Novosibirsk and Irkutsk have the highest rates of HIV in Russia, according to the chief of Russia’s consumer rights watchdog Rospotrebnadzor.

Anna Popova, Rospotrebnadzor head, said these regions also faced high-levels of drug use.

“There are two epidemics in Russia – drug addiction and HIV infections, and geographically they coincide,” the Rospotrebnadzor head said at a youth forum on July 23.

In September 2016, 854,187 Russians registered as living with HIV. The country’s growing HIV rate differs from much of the developed world, where the number of new cases is falling. In 2015, Russian health authorities registered 95,475 new HIV cases, and another 75,962 during the first nine months of 2016.

Alexander Semyonov, head of the immunology and virology lab at the St. Petersburg Pasteur Institute said this March that the disease was increasingly being spread via sexual contact.

“Several years ago the average HIV patient was a drug user consuming two or three doses of heroin every day,” Semyonov told reporters. “These days it’s entrepreneurs, workers, housewives, students — ordinary people.”
