近年来,儿童病毒性心肌炎发病率有上升趋势,应积极探索原因,加强预防。国內的调查资料表明,病毒性心肌炎的发病年龄以学龄前和小学三年级以前发病者较多。他们正处在发育阶段,免疫系统稚嫩,抵抗各种感染能力较差。其发病多因天气变化,气温骤降,一些儿童难以适应,极易患上呼吸道感染和流行性感冒,进而诱发病毒性心肌炎。有人调查发现,孩子母乳喂养者患心肌炎的可能性较小;儿童长期偏食者患心肌炎的可能性偏高。 In recent years, the incidence of viral myocarditis in children has an upward trend, should actively explore the reasons for strengthening prevention. Domestic survey data show that the incidence of viral myocarditis in pre-school and primary third year before the onset of more. They are at a developmental stage with immature immune system and poor ability to resist various infections. The incidence of mostly due to the weather changes, the temperature plunged, some children difficult to adapt, vulnerable to upper respiratory tract infection and influenza, thereby inducing viral myocarditis. Some surveys found that children with breastfeeding are less likely to have myocarditis; children with long-term partial eclipse are highly likely to have myocarditis.
