正确的疾病监测必须以可靠的诊断作为依据。这里仅就我们工作中所遇到的几个例子,谈谈在今后传染病监测中应该注意运用新的诊断技术的重要性。众所周知,病毒性肝炎是我国的一种重要传染病,对肝炎的监测,已经要求把甲、乙、丙、丁、戊五种肝炎区分出来,只根据流行特征和临床表现是难于作出正确回答的,必须借助于特异性的诊断技术。由于麻疹疫苗的普遍应用,出现了许多轻型麻疹,临床上很难与风疹相鉴别,几年 Correct disease surveillance must be based on sound diagnosis. Here are just a few examples we encountered in our work and talk about the importance of paying attention to the application of new diagnostic techniques in the monitoring of infectious diseases in the future. As we all know, viral hepatitis is an important infectious disease in our country. To monitor the hepatitis, it has been required to distinguish the five hepatitis A, B, C, D and E. It is difficult to correctly answer the epidemic characteristics and clinical manifestations , Must rely on specific diagnostic techniques. Due to the universal application of measles vaccine, there have been many cases of light measles that are difficult to distinguish clinically from rubella and several years
