有关鼠疫保存问题的认识及疫源地根治对策的战略考虑

追本溯源，人间鼠疫（腺疫）来自鼠间鼠疫；鼠间鼠疫源于鼠疫自然疫源地；鼠疫自然疫源地的商源，保存并引发于鼠洞（疫洞，疫洞群）。顺其自然，防止人间鼠疫在于控制鼠间鼠疫，控制鼠间鼠疫关键是根治鼠疫自然疫源地；根治鼠疫自然疫源地，灭蚤优于灭鼠，而灭蚤重点在鼠洞。鼠洞（疫洞）有如疫源地生理的心脏，疫理上的恶性肿瘤。抓住鼠洞这个重点，采取包括改造生态环境在内的鼠洞综合治理措施，是根治鼠疫疫源地的重要战略决策。

The Understanding of Persistence Problem Related to Plague and the Strategical Consideration of the Eradicative Countermeasure of Plague Focus

race to its source, the human cases(bubonic plague)originated from rodents plague and the rodentsplague originated from plague natural focus.The pestilence source conserved and detonated in rodents bur-rows(pestilent burrow or burrow groups).The key to the prevention of human plague should depend uponthe control of rodents plague and the key to control of the rodents plague upon the eradication of natural fo-cus. For the eradication of plague natural focus elimination of fleas would be superior to exterminating ro-dents while the key point of fleas elimination was the rodents burrows(pestilent burrow cr burrow groups ).The author considered that the rodent's burrow be just like the heart of the persistence of focus.Therefore,the key point- rodents burrow should be treated by comprehensive measures.This would be the most impor-tant policy decision.
