概括
在加纳,淋巴状细菌病 (LF) 的传播仍在继续,之前被认为非特有的两个地区现在已被证实为特有. 这需要有针对性的大规模药物管理 (MDA) 来控制LF的持续传播.
科学领域:
- 热带医学是一种热带医学.
- 传染病流行病学 传染病流行病学
- 公共卫生监督是对公共卫生的监督.
背景情况:
- 2001年在加纳启动的淋巴丝腺症 (LF) 消除工作,通过大规模药物管理 (MDA) 取得了进展.
- 在以前非流行地区持续的LF传播和报告的发病率需要更新的流行率评估.
- 由于新出现的淋巴结胀和水病例,人们对淋巴结核病发病率表示担忧.
研究的目的:
- 通过确认性映射调查,重新评估不确定的发病率的地区的LF患病率.
- 识别和重新分类正在进行LF传输的地区.
- 引导针对性公共卫生干预以消除LF.
主要方法:
- 一项横截面调查使用了世卫组织批准的LF确认绘图工具,遍及加纳38个地区.
- 采集了9-14岁的学龄儿童的样本,并使用菲拉里亚检测条 (FTS) 测量了循环中的菲拉里亚抗原 (CFA) 水平.
- 如果在480名样本儿童中发现超过三例阳性病例,则分区被归类为特有病例;分区调查证实了这些发现.
主要成果:
- 共有18,459名儿童进行了测试,在17个地区检测到阳性CFA病例.
- 恩科兰扎南区和温市区超过了特有门,其抗原流行率分别为1.68%和4.73%.
- 分区调查证实了这两个地区的高抗原流行率,表明活跃的LF传播.
结论:
- 确认地图调查发现,在两个以前被归类为非特有地区的地区,正在进行的LF传播.
- 恩科兰扎南区和温市政区已被重新归类为特有,需要立即MDA.
- 这项研究强调了重新评估LF特有性和在传染动态不确定的地区实施有针对性的干预措施的必要性.

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
