Human cases of plague, which had virtually disappeared in Madagascar after the 1930s, reappeared in 1990 with more than 200 confirmed or presumptive cases reported each year since. In the port of Mahajanga, plague has been reintroduced, and epidemics occur every year. In Antananarivo, the capital, the number of new cases has increased, and many rodents are infected with Yersinia pestis. Despite surveillance for the sensitivity of Y. pestis and fleas to drugs and insecticides and control measures to prevent the spread of sporadic cases, the elimination of plague has been difficult because the host and reservoir of the bacillus, Rattus rattus, is both a domestic and a sylvatic rat.
鼠疫的人间病例在20世纪30年代后在马达加斯加几乎消失,但在1990年再次出现,此后每年报告200多例确诊或疑似病例。在马任加港,鼠疫再次传入,且每年都会发生疫情。在首都塔那那利佛,新病例数量增加,许多啮齿动物感染了鼠疫耶尔森菌。尽管对鼠疫耶尔森菌和跳蚤对药物及杀虫剂的敏感性进行了监测,并采取了控制措施以防止散发病例的传播,但由于该杆菌的宿主和储存宿主——黑家鼠既是家栖鼠又是野栖鼠,因此消除鼠疫一直很困难。
