小心这些常见寄生虫!危害性高威胁人类健康

虽然医学不断进步,但由寄生虫引起的传染病依然严重威胁人类的健康,每年仍有数十亿人感染各类寄生虫病,轻则罹患疾病,重则随时夺命!以下整理了4种常见寄生虫:

疟原虫(Plasmodium)

疟原虫是古老又原始的单细胞寄生虫,最常透过受感染的雌性疟蚊传播,是引发疟疾的罪魁祸首,全世界40%以上人口皆面临疟疾威胁。

寄生于人体的疟原虫有四种,即间日疟原虫、三日疟原虫、恶性疟原虫与卵形疟原虫,其中恶性疟原虫最为致命,占疟疾死亡率约90%。

常见症状:腹泻、发热、畏寒、疲倦、头痛、恶心、呕吐

钩虫(Ancylostoma duodenale)

人类会因为赤足劳动,手脚皮肤与幼虫接触而感染钩虫病,或因生食含有幼虫的不洁蔬菜、瓜果而受到感染。幼虫在人体內成长,寄生于十二指肠和小肠里,导致人体长期慢性失血,肠功能紊乱、营养不良。

常见症状:虚弱、腹痛、腹泻、恶心、呕吐、贫血

蛔虫( Ascaris lumbricoides)

蛔虫是肠道最常见的寄生虫之一,长度可达35厘米。蛔虫在肠道与宿主竞争养分,严重影响营养吸收。蛔虫也可穿过肠壁,导致肠穿孔与腹膜炎,若没有及时动手术可致命。

常见症状:腹痛、腹泻、咳嗽、气促、哮喘、发烧

蛲虫Enterobius vermicularis)

蛲虫也被称为线虫、屁股虫,是常见的人类寄生虫,成雌虫长度可达13毫米。蛲虫寄生于肠道,并在肛门周围的皮肤上产卵,导致瘙痒,儿童感染率高于成人。

常见症状:肛门或阴道瘙痒、间歇性腹痛、恶心、失眠、阑尾炎

寄生虫无孔不入,若到访卫生条件较差的地方,一定要小心预防,有任何不适症状应及时就医,以免耽误病情!
