Giriş: Crimean-Congo Haemorrhagic Fever (CCHF) is a disease caused by an RNA virus of the Bunyaviridae family, which has affected many people since 1944 and has a high mortality rate. The aim of this study was to evaluate 34 years of research on CCHF, an endemic and widespread disease in Turkey, in the national literature using VOSviewer visualisation methodology and to present a comprehensive bibliographic review. Methods: In this bibliometric analysis, a total of 1850 studies searched with the keyword ‘Crimean-Congo haemorrhagic fever’ in the Web of Science (WoS) database between 1990 and 2025 were examined, and 1507 articles were included in the analysis by eliminating ineligible and non-article studies. Data such as titles of publications, author names, publication years, journal names, citation numbers were collected and countries, institutions, journals, keywords, co-authorship, co-citation, international collaborations and citation rates were evaluated. Results: In the analysis of 1507 articles in the WoS database, a total of 36,693 citations were identified. The average number of citations per article is 24 and the H index is 86. Since 2000, a significant increase has been observed in both the number of publications and citations. Türkiye, USA and Iran were the countries that produced the highest number of publications on CCHF. Conclusion: The findings reveal that studies on CCHF are increasing on a global scale, and Turkey's contribution in this field is remarkable. This study provides a holistic view of the current state of CCHF research and aims to provide guidance for future research.

Ticks are important vectors that pose a risk to both animal and human health because they parasitize by sucking blood and transmitting many pathogenic disease agents. Turkey harbors a large number of tick species due to its location, geographical structure, climate, habitat richness, and animal diversity. This study was designed to investigate the frequency and seasonal distribution of tick species found in sheep, cattle, and goats in the center and districts of Iğdır. Bovine and ovine animals were examined for tick infestation between January and December 2024 in the center and districts of Iğdır, and the shelters where they lived were also examined. A total of 1,050 tick samples obtained from 1,483 animals were collected and transferred to tubes containing 70% ethyl alcohol. Subsequently, these samples were sent to the Parasitology Research Laboratory of the Faculty of Medicine at Van Yüzüncü Yıl University, where the species were identified based on their morphological characteristics using a stereo microscope, in accordance with the relevant literature. Of the ticks examined, 57.52% were female and 42.48% were male. The following tick species were detected: Rhipicephalus turanicus (33%), Rhipicephalus bursa (21.6%), Hyalomma a. anatolicum (17.2%), Hyalomma a. excavatum (20.2%), Hyalomma scupense (3.6%), Ixodes ricinus (0.7%), Hyalomma sulcata (1.5%), Hyalomma punctata (0.4%), and Dermacentor niveus (1.8%). Among these, ticks belonging to the Rhipicephalus genus (54.6%) were the most common. When the tick species detected in the study were evaluated, Rhipicephalus species were found to be most prevalent between May and July. Additionally, the detection of Hyalomma and Rhipicephalus tick species, which are known vectors of the Crimean-Congo Hemorrhagic Fever virus that poses a risk to human health, is important. We believe that this data will serve as a valuable reference for future studies to be conducted in this province.

Bu çalışmanın amacı, gelecekteki bilimsel ve klinik araştırmaların yönünü daha iyi anlayabilmek için Babesia spp. ile ilgili araştırma odaklarını ve eğilimlerini ortaya koymaktır. Babesia spp. ile ilgili makaleler, Web of Science veri tabanından sistematik olarak tarandı. VOSviewer yazılımı kullanılarak, Babesia spp. üzerine yapılan araştırmalarla ilişkilendirilen ülkeler, kurumlar, yazarlar, referanslar ve anahtar kelimeler görsel olarak analiz edildi. Bu bibliyometrik analize toplam 1805 yayın dahil edildi. Bu yayınlar, 1970 ile 2022 yılları arasında, özellikle Amerika Birleşik Devletleri olmak üzere 124 farklı ülkede yayımlanmıştır. En fazla yayın yapılan yıl 2021 olmuştur. Zaman içinde insan babesiosisi ile ilgili yayınların sayısındaki artış, Babesia spp.’nin küresel olarak giderek daha fazla önem kazandığını göstermektedir. İnsan babesiosisi için etkili kontrol stratejileri belirlemek amacıyla, gelişmiş ülkelerdeki araştırmacılar ile gelişmekte olan ülkelerdeki meslektaşlar arasında iş birliği ve ortak araştırmalar teşvik edilmelidir.
