A study just published on Eurosurveillance has found evidence of substantial lifetime exposure to hepatitis B and C viruses in Ukraine in a 2021 nationwide, representative sample of the population, with findings also suggesting significant ongoing circulation of these viruses.
Ahead of World Hepatitis Day 2025, viral hepatitis remains a major global health concern, and is one of the priority infectious diseases under the United Nations’ Sustainable Development Goal 3. [1][2] The World Health Organization (WHO) Global Hepatitis report 2024 estimated an overall hepatitis B virus (HBV) prevalence of 1.2% for the WHO European Region and identified Ukraine as one of six focus countries in the region for its viral hepatitis response. [3]
Diagnostic tests to detect Hepatitis C virus (HCV) core antigen (HCcAg) in the study were interrupted by the Russian invasion of Ukraine. With the war still ongoing and the disruption in public health infrastructure and surveillance, it is difficult to estimate its inevitably negative effect on global efforts to reach the goal of eliminating viral hepatitis as a public health threat by 2030. This was the first population-based serological study in Ukraine to assess HBV and HCV prevalence among the general adult population, despite the pressing need for such data.
Men and older adults more likely to test positive for hepatitis B and C
Researchers from the Public Health Centre of the Ministry of Health of Ukraine and the medical laboratory DILA used blood samples collected in mid-2021 through a nationwide and representative cross-sectional, household-based SARS-CoV-2 serosurvey. The samples from the adult population were tested for hepatitis C virus (HCV) antibodies, total antibodies against hepatitis B virus (HBV) core antigen (HBc), hepatitis B surface antigen (HBsAg) and hepatitis D virus (HDV) antibodies. Researchers then calculated crude and weighted proportions for anti-HCV, anti-HBc and HBsAg positivity, adjusting the data to ensure it reflected actual Ukrainian demographics. Weighted regional estimates and proportions positive for anti-HDV were also calculated among HBsAg-positive cases.
The study found a 3.3% prevalence of hepatitis C antibodies and 11.6% of hepatitis B antibodies, which indicate current or past infection for these viral infections. A prevalence of 0.9% was found for HBsAg, which indicates a current, mainly chronic HBV infection. Among those with HBsAg, 7.5% were anti-HDV positive.
Odds of having anti-HBc increased with age and was highest among those over 60. The prevalence of anti-HCV, anti-HBV and HBsAg was found to be higher in southern regions of Ukraine. Anti-HCV markers were more prevalent among men, in urban areas, and in the eastern and southern regions.
Significant challenges in Ukraine to achieve viral hepatitis elimination targets
These findings emphasise the need of hepatitis B virus (HBV) vaccination among infants and risk groups as well as regular HBV and hepatitis C virus (HCV) screening, treatment, and awareness raising to decrease transmission.
Ukraine joined the WHO’s Global Strategy for the Elimination of HBV and HCV in 2019 [4], and has since expanded HBV screenings in primary care, ensured public funding for diagnosis and treatment, and decentralised care by involving family and non-infectious disease doctors. It has also improved access to HBV services.
Ukraine introduced HBV vaccination in the national childhood immunisation schedule in 2002, achieving vaccination coverage of 88% in 2024. However, the vaccination rate remains below the WHO target of 90% and national surveillance is not fully established. Ukraine’s strategy to eliminate viral hepatitis includes reducing new cases and associated deaths, which requires effective surveillance.
The war on Ukraine has resulted in large-scale internal displacement as well as refugee migration to neighbouring countries, disrupted treatment for Ukrainians in the occupied territories, and hampered healthcare infrastructure, adding to existing challenges in addressing viral hepatitis.

Use of billing codes in big data sets to find diagnoses can result in up to two-thirds of cases being mistakenly identified, new UCLA-led research finds.
Databases frequently used for medical research such as those for the Centers for Medicare & Medicaid Services or the National Inpatient Survey typically rely on ambulatory billing codes to identify diseases or medical procedures, but their accuracy is rarely verified in publications that rely on this data, the researchers write in a report published in the peer-reviewed journal ...

Hospitalizations and emergency department (ED) visits can be distressing and costly for nursing home residents – especially those who are severely impaired or terminally ill. Despite their vulnerability, these individuals are frequently transferred to hospitals, even though up to 40% of such transfers over the past 25 years are considered potentially avoidable by health care professionals.
These unnecessary transfers not only cause distress and discomfort for residents and families but also lead to hospital-acquired complications and added costs for the health care system. In the United States, hospital transfers from nursing homes significantly ...

Schizophrenia is a serious mental health condition that affects thoughts, moods, perceptions, and behaviors. Affected individuals experience positive symptoms like delusions and hallucinations, and negative symptoms like social withdrawal, cognitive deficits, disorganized thoughts and speech, and a decreased experience of pleasure. While schizophrenia is caused by a complex interplay of genetic, environmental, and lifestyle factors, precise mechanisms remain elusive.
Animal models provide valuable insights into the neurobiological mechanisms that underpin schizophrenia. However, conventional behavioral assessments ...

Chemotherapy-induced nausea and vomiting are among the most distressing side effects of anti-cancer treatment, particularly for those receiving highly emetogenic regimens such as anthracycline plus cyclophosphamide combinations. This major side effect compromises a patient’s quality of life and willingness to continue therapy. Therefore, there is a crucial need to devise an effective antiemetic management approach for optimizing cancer care and patient well-being.
Against this backdrop, a new study, led by Professor Mitsue ...

Immune checkpoint inhibitors (ICIs), a powerful form of immunotherapy, have revolutionized cancer treatment by unleashing the body’s own immune system to fight tumors. These compounds target the programmed cell death-ligand 1 (PD-L1), a surface protein typically found on tumor cells, which enables the tumors to avoid recognition by immune T cells. By disrupting PD-L1’s function with specially tailored antibodies, ICI-based strategies have brought hope to countless patients with cancer. However, ...

In a first-of-its-kind experiment tracing evolution across 25 generations, scientists have discovered that marine copepods—the tiny crustaceans at the heart of the ocean food web—rely on a largely unknown biological toolkit to survive the stresses of climate change.
Published July 15, 2025, in the Proceedings of the National Academy of Sciences, the study reveals that it’s not only genetic changes (permanent alterations to DNA) that help these animals adapt to warming and acidifying ocean conditions. In addition, little-known epigenetic changes (temporary “on/off” chemical modifications to parts ...

The accumulation of misfolded proteins in the brain is central to the progression of neurodegenerative diseases like Huntington’s, Alzheimer’s and Parkinson’s. But to the human eye, proteins that are destined to form harmful aggregates don’t look any different than normal proteins. The formation of such aggregates also tends to happen randomly and relatively rapidly – on the scale of minutes. The ability to identify and characterize protein aggregates is essential for understanding and fighting neurodegenerative diseases.
Now, using deep learning, ...

For military veterans, many of the deepest wounds of war are invisible: Traumatic brain injuries resulting from head trauma or blast explosions are a leading cause of post-traumatic stress disorder, anxiety, depression and suicide among veterans. Few treatments have been effective at diminishing the long-term effects of TBI, leaving many veterans feeling hopeless.
Now, Stanford Medicine researchers have discovered that the plant-based psychoactive drug ibogaine, when combined with magnesium to protect the heart, safely and effectively reduces PTSD, anxiety and depression and improves functioning in veterans with TBI.
