HIV/AIDS has reached alarming proportions in the former communist bloc, but countries with successful democracies are beginning to reverse the trend, reads the U.N. Development Program first survey of HIV-AIDS infections in 28 countries of Eastern Europe, the Baltic states and the former Soviet Union. Poland, the Czech Republic and Slovakia are cited as the countries which recorded important success in halting or reversing the spread of the epidemic. The report warns that the rampant disease stifles the economic development of the affected countries, since the highest infection rates are among 15-to-40-year-olds, who make up the bulk of the work force.
