A total of 132,976 cases of AIDS had been reported by 177 countries by the end of 1988, compared to 73,670 reported by the end of 1987, according to a survey by the World Health Organization released in Geneva. The figures represent cumulative totals reported to WHO since 1979. Most of the cases were from the United States, with 80,538 as of Dec. 14. Uganda (5,508) and France (4,874) ranked second and third, although they have not filed reports recently, WHO said. The organization estimates that the actual number of cases worldwide is 350,000 and that at least 5 million people are infected with the virus believed to cause acquired immune deficiency syndrome.
