::شپش( Pediculosis) و راههای مبارزه با آن::



 اگر چه بهبود وضعیت بهداشتی، اقتصادی و اجتماعی تاثیر بسزایی در كاهش آلودگی به شپش داشته است، اما همچنان این انگل گستردگی جهانی دارد، به طوری‌كه در دهه گذشته در ایالات متحده آمریكا هر سال 6 میلیون مورد ابتلا به شپش گزارش می‌شود.

شپش مختص جامعه یا طبقه اجتماعی خاصی نبوده و تمام افراد جامعه را مخصوصا در فصول سرد سال ممكن است درگیر كند. شیوع این بیماری در كودكان بسیار بیشتر است و در جنس مونث شایع‌تر از جنس مذكر است.

ابتلا به شپش سر در تمام جوامع دیده میشود و برای مثال در بچه های مدارس ابتدایی کانادا در هر زمان حدود 2% ابتلا به شپش سر وجود دارد به عبارتی دیگر ابتلا به شپش سر ارتباطی با وضعیت اقتصادی نداشته در تمام طبقات اجتماع ممکن است رخ دهد و حتی در مومیایی های مصر باستان هم رشک های مرده دیده شده است

این حشره، به دنبال تماس‌های نزدیك بین فردی یا هنگامی كه افراد خانواده در فصول سرد برای تامین گرما لباس‌های بیشتری می‌پوشند و به صورت دسته جمعی زندگی می‌كنند، از شخصی به شخص دیگر انتقال می‌یابد.

معرفی شپش:

شپش حشره كوچكی به رنگ سفید مایل به خاكستری است كه دارای دهانی مخصوص مكیدن خون، دو شاخك و سه جفت پای كوتاه است.

شپش یك انگل خارجی بدن انسان محسوب می‌شود. می‌تواند سر، بدن و عانه را آلوده كند. تخم شپش «رشك» نام دارد و بیضی شكل و سفیدرنگ و به اندازه ته سنجاق است و به مو و درز لباس‌ها می‌چسبد.

شپش در مو و لباس زندگی می‌كند و فقط به خاطر تغذیه روی سطح بدن می‌آید و خودش را به پوست بدن می‌چسباند و پوست را سوراخ كرده و بزاق خود را در زیر پوست تزریق نموده و با مكیدن خون، مواد زائدی را نیز از خود دفع می‌كند. همین تلقیح مواد زائد و بزاق به زیر پوست منجر به ایجاد برآمدگی قرمز رنگ خارش‌داری می‌گردد.

از نظر شدت و شیوع آلودگی به انواع شپش، عواملی چون سن، جنس، نژاد، وضعیت اقتصادی و اجتماعی موثر شناخته شده‌اند. آلودگی در تمام گروه‌های سنی دیده می‌شود ولی شپش سر در كودكان (سنین مدارس ابتدایی) شیوع بیشتری دارد.

نكته اینجاست كه اگر چه به طور معمول شپش در جوامع فقیر و متراكم شایع‌تر است، ولی در شرایط همه‌گیری كلیه طبقات اجتماعی و اقتصادی جامعه را فرا می‌گیرد و حتی در جوامع چندنژادی مشاهده شده كه شپش سر در سفیدپوستان شایع‌تر از سیاه‌پوستان است.
