Abstract:
The number of notified measles cases in Poland in 2001 was 133, incidence per 100,000 inhabitants was 0.3. The low incidence has been observed for the last 3 years. Only 73 out of 133 cases were serologically confirmed, 6 other cases were epidemiologically linked to the laboratory confirmed cases. Unvaccinated cases have accounted for almost half of cases. Differences in incidence were noticed across the country and ranged from 0 cases in Opolskie and Zachodniopomorskie voivodeships to 0.7/100,000 in Małopolskie and 1.0/100,000 in Swietokrzyskie voivodeship. The highest incidence was observed in the children one year of age (3.7/100,000) and seven years old (2.3/100,000), however, in general, the age distribution of cases has been shifted toward older ages with 44 cases (33% of all cases) in adults. A proportion of children 13-24 months of age vaccinated with first dose of measles vaccine was 77.1%, and proportion of seven years old children vaccinated with second dose of measles vaccine was 81.7%.
Insights
Poland reported low measles incidence in 2001, with unvaccinated cases comprising nearly half of the 133 total cases. Regional variations and a shift towards older age groups were observed, despite vaccination rates nearing 80% for the first dose.
Area of Science:
- Epidemiology
- Public Health
- Infectious Disease Surveillance
Context:
- Measles (Morbillivirus) remains a significant public health concern globally.
- Maintaining high vaccination coverage is crucial for controlling measles transmission.
- Poland has experienced low measles incidence in recent years.
Purpose:
- To analyze the epidemiological characteristics of notified measles cases in Poland in 2001.
- To assess the serological confirmation and vaccination status of measles cases.
- To identify age and regional variations in measles incidence.
Summary:
- In 2001, Poland recorded 133 measles cases, with an overall incidence of 0.3 per 100,000 population.
- Only 55% of cases were serologically confirmed; unvaccinated individuals represented nearly half of all cases.
- Incidence varied regionally, and the age distribution showed a shift towards older children and adults, despite high vaccination coverage in young children.
Impact:
- Findings underscore the importance of sustained high vaccination rates to prevent measles outbreaks.
- Identifies specific age groups and regions requiring targeted public health interventions.
- Highlights the need for robust surveillance and serological confirmation of measles cases.
