Hepatitis A in Poland in 2015

Area of Science:

• Epidemiology
• Public Health
• Infectious Diseases

Background:

• Hepatitis A remains a significant public health concern globally.
• Understanding the epidemiological trends of Hepatitis A is crucial for effective disease control.
• Poland has implemented surveillance systems to monitor infectious diseases, including Hepatitis A.

Purpose of the Study:

• To assess the epidemiological situation of Hepatitis A in Poland during 2015.
• To analyze trends in Hepatitis A incidence in relation to previous years.
• To identify potential areas for improvement in Hepatitis A surveillance and vaccination policies.

Main Methods:

• Analysis of data from official bulletins on infectious diseases and vaccinations in Poland for 2015.
• Review of individual case questionnaires and epidemiological investigation reports for Hepatitis A outbreaks.
• Data compilation and analysis by the Department of Epidemiology at the National Institute of Public Health – National Institute of Hygiene (NIPH-NIH).

Main Results:

• In 2015, Poland registered 49 cases of Hepatitis A, with an overall incidence of 0.13 per 100,000 inhabitants.
• Incidence varied across voivodeships, ranging from 0.03 to 0.36 per 100,000 population.
• The incidence rates between males (0.11/100,000) and females (0.15/100,000) were similar.

Conclusions:

• Despite a decrease in cases compared to the previous year, the overall epidemiological situation of Hepatitis A in Poland did not significantly change in 2015.
• Current surveillance lacks data on the risk group affiliation of vaccinated individuals, hindering targeted vaccination policy recommendations.
• Maintaining a high level of routine surveillance is essential due to an increasing susceptible population.
