Epidemiological Perspectives: A Four-Year Insight Into Hepatitis C Surveillance in the Kingdom of Saudi Arabia.

Introduction Hepatitis C is a viral disease caused by the hepatitis C virus (HCV), a member of the family. This compact, enveloped RNA virus possesses a positive single-stranded genome and can be transmitted through various means, including blood exposure, sexual contact, and vertical transmission. The disease is associated with significant morbidity and mortality, imposing substantial costs on the healthcare system. In Saudi Arabia, HCV is a notifiable disease; however, there is a scarcity of recent reports on HCV trends in the country. This study aims to provide updated insights into the infection patterns of HCV across demographics, regions, and genders in Saudi Arabia. Methods A retrospective analysis was conducted to investigate the epidemiological trends of HCV infection in Saudi Arabia. Data were obtained from the Saudi Ministry of Health (MOH), encompassing the timeframe from 2019 to 2022. A descriptive analysis of HCV infection, organized by year, age group, and gender, was conducted using the data reported to the MOH. Results Between 2019 and 2022, there was a significant decrease of 56.9% in the overall rate of hepatitis C cases in Saudi Arabia. The rate dropped from 9.94 to 4.29 cases per 100,000 people during this period. Males consistently had higher reported cases compared to females, although there was a notable decline in cases for both genders from 2019 to 2022. The highest incidence of HCV was found in individuals aged 45 years and above. However, there was a decline in cases among this age group, with the number dropping from 2,195 cases in 2019 to 946 cases in 2022. In terms of regional variations, Riyadh, Makkah, Jeddah, Alsharqiya, and Taif had the highest incidence of HCV cases. Some regions experienced an increase in cases between 2021 and 2022, particularly Jeddah, Taif, and Al-Ahsaa. Conclusion This study reveals a significant reduction in reported HCV cases in Saudi Arabia from 2019 to 2022. However, gender disparities persist, with males having a higher number of reported cases. There is also a notable decline in HCV cases among children and adolescents, which can be attributed to preventive measures. The findings emphasize the importance of region-specific strategies, as certain areas, such as Riyadh, Makkah, Jeddah, Alsharqiya, and Taif, continue to have a high number of reported cases. Proactive measures, surveillance, and public awareness campaigns remain crucial in addressing HCV as a significant public health challenge in the Kingdom.
