流行性感冒(简称流感)是一种传染性极强的疾病,多发于冬春季节。虽然流感在日常生活中是常见病,但由于流感使机体抗病力下降可导致其他疾病,如并发急性肺炎、心肌炎以及肾炎等疾病,慢性病患者也可因流感使病情恶化。对于年老体弱者来说,流感更是一个威胁极大的传染病,因为它除了可引起发烧和全身不适外,还易使原患有肺心病、冠心病的患者病情加重,甚至导致死亡,因此必须重视流感。 Influenza (flu) is a highly contagious disease, mainly in winter and spring. Although flu is a common disease in daily life, other diseases such as acute pneumonia, myocarditis and nephritis may also occur due to the flu resistance to the body. Patients with chronic diseases may also make the flu worse. For the elderly and the infirm, the flu is a threat to infectious diseases, because it can cause fever and general malaise, but also easy to make the original patients with cor pulmonale, coronary heart disease patients exacerbate, and even lead to death, Therefore, we must pay attention to flu.
