The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which led to the COVID-19 pandemic, has significantly impacted global public health. The proper diagnosis of SARS-CoV-2 infection is essential for the effective control and management of the disease. This study investigated the SARS-CoV-2 infection using RT-qPCR tests from laboratories in Bosnia and Herzegovina. We performed a retrospective study of demographic data and Ct values from 170,828 RT-qPCR tests from April 2020 to April 2023, representing 9.3% of total national testing. Samples were collected from 83,413 individuals across different age groups. Of all tests, 33.4% were positive for SARS-CoV-2, with Ct values and positivity rates varying across demographics and epidemic waves. The distribution was skewed towards older age groups, although lower positivity rates were observed in younger age groups. Ct values, indicative of viral load, ranged from 12.5 to 38. Lower Ct values correlated with higher positive case numbers, while higher Ct values signaled outbreak resolution. Additionally, Ct values decreased during epidemic waves but increased with the dominance of certain variants. Ct value-distribution has changed over time, particularly after the introduction of SARS-CoV-2 variants of interest/concern. Established Ct value trends might, therefore, be used as an early indicator and additional tool for informed decisions by public health authorities in SARS-CoV-2 and future prospective pandemics. Moreover, they should not be overlooked in future epidemiological events. [ABSTRACT FROM AUTHOR]

Association of Gastroenterologists and Hepatologists of Bosnia and Herzegovina based on the experiences of domestic and foreign centers operating in the field of hepatology and accepted guidelines of the European and the U.S. Association for Liver Diseases adopted the consensus for the diagnosis and treatment of chronic viral hepatitis B and C. The guidelines are intended for specialists in gastroenterology and hepatology, and infectious diseases physicians working in primary health care and family medicine, but also other physicians who are confronted with this disease in their practice, with the aim of facilitating and shortening the diagnostic and treatment protocols of patients with chronic viral hepatitis B and C. This ensures faster, more efficient, more rational and cost-effective care of patients with hepatitis, with an emphasis on stopping the deterioration of liver disease to liver cirrhosis and eventually hepatocellular carcinoma.
