Journals of the Plague Years — Norman Spinrad

The Plague's origins were mysterious, but its consequences were all too obvious: quarantined cities, safe-sex machines, Sex Police, the outlawing of old-fashioned love. Four people hold the fate of humanity in their hands...A sexual mercenary condemned to death as a foot soldier in the Army of the Living Dead; a scientist who's devoted his whole life to destroying the virus and now discovers he has only ten weeks to succeed; a God-fearing fundamentalist on his way to the presidency before he accepts a higher calling; and a young infected coed from Berkeley on a bizarre crusade to save the world with a new religion of carnal abandon. Each will discover that the only thing more dangerous than the Plague is the cure.
