Summary
Hepatitis B cases in Poland saw a decline in acute infections but a rise in chronic diagnoses in 2021, with COVID-19 impacting surveillance. Hepatitis B vaccination coverage for infants slightly decreased.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- The COVID-19 pandemic has influenced healthcare systems and disease surveillance globally.
- Understanding the epidemiological trends of viral hepatitis is crucial for public health interventions.
Purpose of the Study:
- To evaluate the epidemiological situation of hepatitis B in Poland in 2021.
- To compare 2021 data with previous years, considering the impact of the COVID-19 pandemic.
Main Methods:
- Analysis of individual hepatitis B case reports and HBV infections from the EpiBaza system.
- Utilized aggregate data from national bulletins on infectious diseases and vaccinations.
- Incorporated mortality data from Statistics Poland (GUS).
Main Results:
- 1,547 hepatitis B cases registered in 2021, with a significant decrease in acute hepatitis B incidence (0.03/100,000).
- Chronic or unknown-phase hepatitis B cases increased by 58% compared to 2020, though lower than the 2015-2019 median.
- Hepatitis B vaccination coverage (HepB3) for 1-year-olds slightly decreased to 89.3%.
Conclusions:
- The COVID-19 pandemic likely affected the surveillance of hepatitis B, contributing to the observed trends.
- A leveling of chronic case diagnoses and a further decline in acute cases were noted.
- Continued decline in infant hepatitis B vaccination coverage is a concern.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
