流感是我们熟知的一种急性传染病,在世界各地呈周期性流行出现。在流行期间,有时在一团体内可有20%以上的人在2—3周内被感染,亚临床性感染为数更多。此外流感可能引起一些合并症,在重笃的病例更可危及生命。虽然近20余年来流感的病因学、临床病学和实验诊断方面有较多的进展,但在预防和治疗上还存在着不少问题亟待解决。兹提出有关流感的几个问题讨论一下,希望能引起同道们对本病的重视。 Flu is a well-known acute infectious disease that appears cyclical throughout the world. During the epidemic, sometimes more than 20% of people in a group are infected within 2-3 weeks, with a greater number of subclinical infections. In addition, flu may cause some comorbidities, which can be even more life-threatening in the case of severe obesity. Although more progress has been made in the etiology, clinical medicine and laboratory diagnosis of influenza over the past 20 years, there are still many problems to be solved in the prevention and treatment of influenza. I’d like to discuss a few questions about the flu and I hope it will arouse the attention of my fellow citizens on this disease.
