İnsanlık tarihi, pek çok felaketin yanı sıra mikroorganizmaların sebep olduğu “salgın’’lar (epidemi/pandemi) ile doludur. Açlık, kıtlık, yoksulluk, iç savaş ve bunlara bağlı göçler, epideminin dünyaya yayılmasına, yani “pandemi”ye olur. Bunlardan kolera 19. yüzyıla kadar, Hindistan’da yaygın mahallî bir hastalık iken, işgalci İngiliz askerleri tarafından Afganistan’a deniz yoluyla Asya, İran, Hicaz Çin’e kadar taşınmıştır. Osmanlı Devleti de, aldığı tüm ön- lemlere rağmen hacıların taşıdığı...
