- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 在全球范围内,中东和北非 (MENA) 地区面临着型肝炎病毒 (HCV) 感染的最高负担.
- 直接作用抗病毒药物 (DAA) 在中东和北非地区为消除HCV提供了重大机会.
- 在19个MENA国家评估了HCV治疗作为预防 (HCV-TasP) 策略的影响.
研究的目的:
- 评估HCV治疗作为预防 (HCV-TasP) 对MENA地区HCV流行病控制的潜在影响.
- 模拟两个治疗推广场景,旨在到2030年显著减少HCV发病率.
- 确定实现HCV消除目标所需的治疗次数.
主要方法:
- 用一个年龄结构化的数学模型来模拟HCV传播动态.
- 该模型使用从中东北非国家系统收集的HCV抗体流行数据进行校准.
- 分析了两个初级治疗推广场景:到2030年减少80%的发病率和发病率<100,000人/年1人.
主要成果:
- 在80%的发病率降低场景下,治疗覆盖率有所不同 (中位数为60.4%),发病率大幅下降 (中位数为每10万人/年3.2).
- 在每10万人年发病率<1的情况下,需要更高的治疗覆盖率 (中位数为87.5%),从而实现了显著的发病率降低 (中位数为90.7%).

Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
