الصين تحت المجهر: تتبع كهوف الخفافيش لمعرفة منشأ فيروس كورونا

قال بيتر دازاك – عالم الحيوان – إن الفريق في ووهان يتلقى معلومات جديدة حول كيف أدى الفيروس ، الذي تم التعرف عليه لأول مرة في المدينة في أواخر عام 2019 إلى وباء ، لكنه لم يقدم مزيدًا من التفاصيل وقال إنه لا يوجد دليل على أنها جاءت من المختبر.

تم تسييس أصول فيروس كورونا إلى حد كبير بعد مزاعم خاصة من الولايات المتحدة ، بأن الصين لم تكن شفافة في إدارتها الأولية لتفشي المرض.

روجت بكين لفكرة أن الفيروس جاء من مكان آخر.

شارك دازاك في التحقيق في أصل مرض الالتهاب الرئوي الحاد (سارس) في 2002-2003 ، واكتشف جذوره في الخفافيش التي تعيش في كهف في مقاطعة يونان الجنوبية الغربية.

قال دازاك رئيس تحالف EcoHealth ومقره نيويورك: يجب إجراء بحث مماثل إذا أردنا العثور على الأصل الحقيقي للحياة البرية.

وقال لرويترز في مقابلة مهمة البحث عن المصدر المحتمل للخفاش مهمة لأننا إذا وجدنا مصادر هذه الفيروسات القاتلة يمكننا تقليل الاتصال بهذه الحيوانات.

من غير الواضح ما إذا كانت الصين تأخذ عينات من العديد من كهوف الخفافيش في البلاد ، ولكن تم العثور على فيروسات تشبه السارس في مقاطعة يوننان الجنوبية الغربية.

وقال دازاك إن فريق منظمة الصحة العالمية في ووهان يتلقى معلومات جديدة حول الكيفية التي أدى بها الفيروس إلى جائحة ، لكنه لم يذكر مزيدًا من التفاصيل.

وقال: أرى صورة تظهر من خلال بعض السيناريوهات التي تبدو أكثر منطقية من ذي قبل.

أحد السيناريوهات التي يدرسها الفريق عن كثب هو احتمال انتشار الفيروس قبل فترة طويلة من تحديده لأول مرة في ووهان.

وقال دازاك: إنه شيء يبحث عنه فريقنا عن كثب لمعرفة مستوى انتقال العدوى في المجتمع الذي ربما كان موجودًا في وقت سابق.

(العمل الحقيقي الذي نقوم به هنا هو أن نبدأ بالحالات الأولى لخزان حيواني ، وهذا مسار أكثر تعقيدًا ، وكان من الممكن أن يحدث منذ شهور أو حتى سنوات).

زار الباحثون المستشفيات ومنشآت الأبحاث وسوق المأكولات البحرية حيث تم تحديد الوباء الأول ، على الرغم من أن جهات اتصالهم في ووهان تقتصر على الزيارات التي يستضيفها مضيفوهم الصينيون.

وقال دازاك إن السلطات الصينية لم ترفض أيًا من طلبات المجموعة لزيارة منشآت أو مقابلة أشخاص منتقدين .

وقال دازاك: بالطبع من المستحيل معرفة ما لم يتم إخبارنا به ، لكن ما أراه في الصين ، وما تراه هذه المجموعة في الصين ، هو أن ما طلبناه ، مسموح لنا بفعله.
