Crimean-Congo hemorrhagic fever (CCHF) is a serious viral disease caused by a virus of the genus Nairovirus. It is transmitted mainly by ticks and, in some cases, by contact with infected blood or body fluids. CCHF is endemic in several parts of Africa. This study focuses on cases of CCHF in Senegal in 2023, and on the actions implemented to manage the epidemic.
A retrospective study was conducted to analyze the 2023 CCHF epidemic in Senegal. The Syndrome Sentinel Surveillance Network (4S Network) was used to detect cases. The reference laboratory used ELISA and PCR tests to confirm diagnoses, while the health emergency operations center coordinated the response using an incident management system (IMS) implemented at the national and regional level.
In 2023, Senegal reported 11 confirmed cases of CCHF in 7 regions, with a case fatality rate of 36.6%. The average time from symptom onset to laboratory diagnosis was 10 days, which sometimes led to delays in case management. Follow-up of 413 contacts was carried out, with no secondary cases identified. Preventive measures, including awareness-raising campaigns in high-risk areas, were also taken.
CCHF represents a persistent threat to public health in Senegal. Surveillance efforts, rapid detection, and the control measures put in place have proved essential in limiting transmission. The observed delays in diagnosis highlight the need to strengthen diagnostic capabilities and improve the responsiveness of the health care system, in particular via implementation of the 7-1-7 framework. Increased intersectoral collaboration is essential to improving containment of this emerging zoonosis.
克里米亚-刚果出血热（CCHF）是一种由内罗病毒属病毒引起的严重病毒性疾病。它主要通过蜱传播，在某些情况下，也可通过接触受感染的血液或体液传播。CCHF在非洲的几个地区呈地方性流行。本研究聚焦于2023年塞内加尔的CCHF病例以及为应对该疫情所采取的行动。
开展了一项回顾性研究，以分析2023年塞内加尔的CCHF疫情。利用综合征哨点监测网络（4S网络）来检测病例。参考实验室使用酶联免疫吸附测定（ELISA）和聚合酶链反应（PCR）检测来确诊，而卫生应急行动中心使用在国家和地区层面实施的事件管理系统（IMS）来协调应对工作。
2023年，塞内加尔在7个地区报告了11例确诊的CCHF病例，病死率为36.6%。从症状出现到实验室诊断的平均时间为10天，这有时导致病例管理出现延误。对413名接触者进行了随访，未发现二代病例。还采取了预防措施，包括在高风险地区开展提高认识运动。
CCHF对塞内加尔的公共卫生构成持续威胁。监测工作、快速检测以及所采取的控制措施已证明对限制传播至关重要。观察到的诊断延误凸显了加强诊断能力以及提高卫生保健系统反应能力的必要性，特别是通过实施7-1-7框架。加强部门间合作对于更好地控制这种新出现的人畜共患病至关重要。
