BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease with a Case Fatality Ratio (CFR) of 10-40 %. It spreads from livestock to humans primarily through tick bites. It is crucial to monitor the peak months of this endemic disease in Afghanistan. Currently, the country is grappling with a potential national outbreak of CCHF, facing limitations in both diagnostic and preventive measures. Therefore, this study aims to describe CCHF prevalence during spike months (June-September) from 2015 to 2024, coinciding with Eid-al-Adha, and assess CCHF familiarity among inhabitants in eight regions of Afghanistan. METHOD: We have analyzed the National Surveillance System data (2015-2024) on retrospective basis. A structured questionnaire was developed to assess CCHF knowledge among inhabitants of eight regions. Data analysis included percentages, frequencies, chi-square tests, using SPSS and power BI. RESULTS: The national surveillance system recorded 1796 CCHF confirmed cases with 238 deaths during spike months from 2015 to 2024. The highest number of Reported cases was in 2023 (734 cases, 78 deaths), followed by 2022 (221 cases). During Eid-al-Adha months from 2015 to 2024, there were 804 CCHF cases and 176 deaths, with the most in 2023 (313 cases, 78 deaths) and the fewest in 2015 (7 cases, 2 deaths). A survey of 1440 inhabitants (80 % male, 20 % female) across eight regions of Afghanistan showed knowledge of CCHF varied within regions. Correct responses were ...
