Summary
Mumps cases in Poland decreased in 2021 due to COVID-19 pandemic restrictions, with lower incidence observed compared to 2020. Continued access issues may underreport actual mumps cases.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- Mumps is a contagious viral illness primarily affecting children.
- Poland mandates mumps vaccination using the MMR vaccine since 2003.
- The study examines mumps epidemiology in Poland.
Purpose of the Study:
- To evaluate mumps epidemiological indicators in Poland for 2021.
- To compare 2021 data with previous years.
- To assess the impact of the COVID-19 pandemic on mumps incidence.
Main Methods:
- Analysis of epidemiological data from official Polish reports.
- Utilized bulletins on infectious diseases and immunizations in Poland for 2021.
Main Results:
- 484 mumps cases reported in Poland in 2021, with an incidence of 1.3 per 100,000.
- Highest incidence in children aged 0-9 and in Pomorskie Province.
- Incidence in men (1.4/100,000) was higher than in women (1.1/100,000).
Conclusions:
- The pandemic's restrictions likely contributed to the reduced mumps cases.
- Underreporting may occur due to limited patient access to primary care.
- Mumps surveillance data requires careful interpretation considering access barriers.
