小朋友,你知道什么是蛔虫吗?它是一种寄生虫,它的形状和蚯蚓很相似,而且它的虫卵很小,用我们的肉眼是看不见的。若平时我们不注意个人卫生,比如饭前便后不洗手,吃东西时不干净等,就最易遭到这些“细致入微”的“黑客”的攻击。进入肚中的蛔虫卵在你营养充足、温暖的肠道中。 Children, do you know what a roundworm is? It is a parasite whose shape resembles that of earthworms and whose eggs are small and invisible to our naked eye. If we usually do not pay attention to personal hygiene, such as not washing hands before meals and after meals, eating unclean, etc., they are most vulnerable to these “meticulous” hacking attacks. Ascaris eggs into the stomach in your nutrient-rich, warm gut.
