Determination of antibodies to HIV virus by the ELISA technique was performed in 27,652 serum samples from January 1988 to November 1989. Samples which were positive twice underwent the Western Blot technique. A 0.41% of positiveness to the virus was found in 1988 and a 0.34% in 1989. Confirmation of positive cases by Western Blot was statistically significant in 1989.
1988年1月至1989年11月期间,采用酶联免疫吸附测定(ELISA)技术对27,652份血清样本进行了HIV病毒抗体检测。两次检测呈阳性的样本采用了蛋白质印迹法(Western Blot)。1988年发现病毒阳性率为0.41%,1989年为0.34%。1989年,通过蛋白质印迹法对阳性病例的确认具有统计学意义。
