2023年6月2日,坦桑尼亚联合共和国卫生部宣布,该国首次记录的马尔堡病毒病暴发结束。3月21日至5月31日期间,共报告了9例病例(8例实验室确诊病例和1例疑似病例)。所有病例均从卡盖拉地区布科巴区报告。暴发期间共报告6例死亡(病死率67%)。
On 2 June 2023, the Ministry of Health of the United Republic of Tanzania declared the end of its first documented outbreak of Marburg virus disease (MVD). Between 21 March and 31 May, a total of nine cases (eight laboratory-confirmed and one probable) were reported. All cases were reported from Bukoba district, Kagera region. A total of six deaths (case fatality ratio 67%) were reported during the outbreak.
In accordance with WHO recommendations, the declaration was made 42 days (twice the maximum incubation period for Marburg virus infection) after the last possible exposure to an MVD probable or confirmed case.
WHO encourages countries to maintain most response activities for three months after the outbreak ends. This is to make sure that if the disease re-emerges, health authorities would be able to detect it immediately, prevent the disease from spreading again, and ultimately save lives.
