في الأشهر الأخيرة ، لم نصافح بأيدينا ونترك مسافة متر ونصف.
نبقى في المنزل مع الشكاوى وما زلنا على بعد متر ونصف من أحبائهم خارج منزلنا.
هذه التدابير تحمينا نحن وأحبائنا ضد الفيروس . ولكن هل تؤثر إجراءات الكورونا فعليًا على جهاز المناعة لدينا؟

وماذا عن الفيروسات والأمراض الأخرى ؟

نسأل أستاذ علم المناعة جير ريكرز من كلية روزفلت الجامعية في ميدلبورغ. يشرح لنا أولاً كيف يمكن أن تنتشر الفيروسات والبكتيريا.

"إنه يختلف ، ولكن هناك أربع طرق للتوزيع غالبًا ما تحدث. أولاً وقبل كل شيء ، يمكنك استنشاق جزيء الفيروس عبر الهواء. ولكن يمكنك أيضًا الاتصال بالبكتيريا عبر السطح." يذكر Rijkers خد شخص ما كمثال ، إذا أعطيته ثلاث قبلات للتحية. ولكن يمكن أن ينتشر المرض من خلال الطعام أو الأعضاء التناسلية.

تضمن إجراءات الكورونا أن يكون لدينا اتصال أقل مباشرة مع الآخرين خارج أسرتنا. "لم يبق أحد في المنزل طوال الوقت. ولهذا أعتقد أن الحفاظ على المسافة هو أهم شيء لتجنب الانتشار".

منع الانتشار
ولكننا أيضًا لا نتصافح ، ولا نقبّل ، ونغسل أيدينا كثيرًا ، ونعطس ونسعل في مرفقنا. كل ذلك لمنع انتشار الفيروس .

هل يساعد هذا أيضًا على مكافحة الإنفلونزا وفيروسات البرد؟ نعم ، يقول ريكيرس. ومع ذلك ، فإن فيروسات الإنفلونزا والبرد تظهر بشكل رئيسي في الشتاء وأقل في الصيف. "حتى لو لم يكن هناك كورونا ولا يوجد إجراء واحد ونصف ، فإن شهر يونيو ليس شهرًا به الكثير من الإنفلونزا في هولندا."

في الهواء الطلق ، يكون انتشار الفيروس أقل سهولة

يرى Rijkers أن الفيروسات التي تحدث على مدار السنة هي أيضًا أقل شيوعًا. مثل نوروفيروس. "يؤثر هذا الفيروس بشكل رئيسي على كبار السن وينتشر بسهولة في الأماكن التي تضم مجموعات مثل السفن السياحية أو دور رعاية المسنين." بسبب فيروس كورونا ، لم تعد السفن السياحية تبحر تقريبًا. تلتزم دور التمريض بقواعد صارمة. "هذا يعني أقل من نصف حالات النورو."

مثال آخر هو الكلاميديا. لا ، ليس هذا لأن العاملين بالجنس غير نشطين. "لقد التزموا دائمًا بقواعد النظافة الصارمة. لقد انخفضت هذه العدوى لأن الناس يبقون في المنزل وبالتالي لديهم عدد أقل من الاتصالات الجنسية."
ولكن ماذا تعني هذه الانخفاضات والتدابير في الواقع لنظام المناعة لدينا؟ يقول ريكرز إن المكان هادئ في الواقع. "يهدف جهاز المناعة لدينا إلى منع العدوى ومكافحتها. وميزة التدابير أنها أصبحت الآن سهلة ، لأننا أقل تعرضًا للعدوى".

الجهاز المناعي البطيء
هذا له أيضًا عيوب. لا يتم تحفيز الجهاز المناعي للبقاء نشطًا. "تخيل أنه ليس لديك ما تفعله ، فإن أي نشاط يبدو أكثر من اللازم. ولكن إذا كنت تعيش حياة نشطة ، فهناك دائمًا شيء تضيفه."

هذه هي أيضًا طريقة عملها مع جهاز المناعة. Rijkers: "يجب تشجيعه بانتظام للبقاء نشيطًا ، وإلا سيصبح كسولًا."

يتراكم الجهاز المناعي منذ الطفولة. ماذا عن الأطفال الآن؟

يقول عالم المناعة أنه من الجيد للأطفال إذا تعرضوا لمسببات الأمراض. "إنه يمنحهم نظامًا مناعيًا متوازنًا. حتى إذا كنت تعاني من أنف مخاطية والتهاب ، فهذا أمر جيد لبناء الأجسام المضادة."

مع بعض الأمراض يكون الأمر أكثر متعة إذا كنت تحصل عليه في سن مبكرة. "مثل عدوى الأذن ، وينطبق أيضًا على الفيروس الكورونا. يبدو أن الأطفال الذين يتلامسون مع الفيروس لا يمرضون منه تقريبًا. لكنهم سيصبحون محصنين ضد هذا الاتصال".

هل أنت محصن إذا كان لديك كورونا؟
على المدى الطويل
كل شيء جميل ولطيف ، قطرات التلوث وأنظمة المناعة البطيئة ، ولكن هل يجب علينا دائمًا الالتزام بهذه التدابير؟ Rijkers لا يعتقد ذلك.

"لا يمكن الحفاظ على جميع جوانب المجتمع الذي يبلغ ارتفاعه متر ونصف المتر ، ولكن سيستمر عدد من الإجراءات للمساعدة في منع انتشار الأمراض المعدية." وأوضح أستاذ علم المناعة بالفعل مثل تدابير النظافة ، لأنها لا تمنع فقط انتشار الكورونا.

على المدى الطويل ، قد تنقلب بعض الإجراءات ضدنا أيضًا. مثل غسل اليدين المتكرر واستخدام المطهرات. هذا يقتل كل شيء على يديك. كذلك البكتيريا الجيدة. "لأن هذه البكتيريا على جلدك ، لا توجد فرصة لمسببات الأمراض الأخرى." يعمل كحاجز طبيعي. "إذا قمت بإزالة هذا الحاجز ، فهناك احتمال طويل الأمد أن يبقى العامل الممرض في يديك."

بالإضافة إلى ذلك ، تصبح يديك قاسية جدًا بسبب الغسيل الشامل. "الطبقة الطبيعية من الدهون تختفي وتظهر تشققات على يديك. وهذا يشبه الباب المفتوح لجزيئات البكتيريا والفيروسات."
