**Background:** The COVID-19 pandemic prompted a global shift in epidemiological research toward understanding the emergence and interconnections of new infectious diseases. Saudi Arabia experienced serious early spread, particularly in densely populated urban areas such as Riyadh, Makkah, and Madina, but implemented strategic measures including the Riyadh Declaration on Digital Health in August 2020. This review consolidates published academic research on COVID-19 in Saudi Arabia to contribute to the knowledge base for future pandemic preparedness and planning.
**Methods:** An online survey of published academic research from peer-reviewed journals was conducted during August–December 2022, using 'COVID-19 in Saudi Arabia' as the search criterion. All available research studies published on academic journals since 2020 were selected, reviewed, and included relevantly. Studies outside the context—such as explanations, case studies, laboratory experimentations, and clinical trials—were excluded. The reviewed research was classified into ten major areas: spread and burden, patient statistics, symptoms and other clinical dimensions, vaccinations and vaccine acceptance/hesitance, psychosocial impact, impact on education, impact on health staff, impact on migration, impact on nutrition, and control measures adopted.
**Key Results:** The review found that COVID-19 entered Saudi Arabia through the eastern region in March 2020 via routes from Iran and China, spreading rapidly to highly populated areas. Old age (above 60 years) was identified as a high-risk group. Females, natives, early adults, and employed persons in direct contact were more affected. Foreigners with a history of chronic diseases including diabetes, hypertension, and thyroid were more likely to exhibit severe conditions. Patients with diabetes were at high risk of disease severity and mortality. A clinical study of blood groups showed significant effects of old age and diabetes on severe infection, while youths and men were also severely infected, attributed to mobility, smoking, and obesity. Vaccine acceptance was higher among males, non-natives, and governmental sector employees. Vaccine side effects included fatigue, pain at the vaccine site, fever, chills, and headache, more so during the second dose. Higher levels of depression and anxiety were reported among the general population of Riyadh, especially among females, younger individuals, and those with a history of psychiatric illnesses. Psychological distress affected health workers engaged in COVID-19 duties, higher among males but without affecting their daily life. Educational institutions shifted to e-learning, facing both acceptance and rejection, with delays in examinations. Healthcare workers experienced increased adverse psychological impact including anxieties and stress due to risk of infection, high workload, stigma, and lack of necessary equipment. Migrants were found to be more prone to infection due to crowded living arrangements. Positive nutrition practices were noted, including a change in dietary patterns toward home-cooked meals with healthy food choices. Control measures included virtual clinic initiatives, e-prescriptions, cancellation of Umrah and Hajj, free COVID-19 treatment for all residents including visa violators, and a tele-counseling network established by the Ministry of Health. The review notes that Saudi Arabia's fight against COVID-19 progressed through phases—green (low infection), yellow (caution), orange (seriousness), and red (danger)—with waves of second and third infections, eventually moving to a green stage characterized by regained lifestyle after vaccine launch.
**Clinical Implications:** This consolidation of research findings demonstrates the scientific academic community's alertness in responding to the pandemic emergency, which facilitated strategy and policy formulations by government ministries and governing bodies. The research is linked to stagewise programmatic efforts to curtail the epidemic. The review emphasizes the importance of digital health infrastructure, telemedicine, and virtual clinics for maintaining healthcare access during emergencies. The findings underscore the need for targeted interventions for high-risk groups including the elderly, those with comorbidities (diabetes, hypertension, cardiac diseases), and migrants in crowded living conditions. The review highlights the importance of vaccine literacy programs to overcome misconceptions and hesitancy, and psychological support programs for healthcare workers and the general population. The experience documented in Saudi Arabia provides a model for disaster preparedness and epidemic control that can inform future emergency responses.
