Russia got hit BAD, especially during the Yeltsin years.
There was wide spread belief that Russia would be unaffected by it as they had been in the 80s (when travel was minimal) combined with the tremendous social collapse that hit Russia at the time.
The biggest thing that contributed to the epidemic in Russia in the 90s and 2000s was (and is) IV drug use. It wasn't a problem in the 80s because the Soviets kept a very tight lid on drugs in the USSR, although even by the late 80s there was some opiates sneaking in from Afghanistan. But the effects of the conclusion of the Afghan war, the civil war, and the rise of the Taliban should be made to include the fact that 70% of the heroin Afghanistan produced went straight to Russia at a time when its poor and drug-abusing population was exploding, and the authorities had neither the time nor the inclination to care about it (they generally disregarded Western advice on the topic, for a variety of reasons, none of which make any sense).
