[Measles in Norway. The first 6 months of 1988]
Abstract:
The incidence rate of measles in Norway in the first six months of 1988 was 2.6 per 100,000. This is the lowest half-yearly incidence rate registered in Norway, but because of a change in the method of reporting the figures are not directly comparable. There was an epidemic in Norway's northernmost county (Finnmark) and an outbreak in an army camp in the county of Troms (also in the north). On a national basis 48% of the cases were preventable, but there were considerable local variations. In Finnmark 77% of cases were preventable. No serious complications (death or encephalitis) were registered but the rate of other complications was higher than expected. There was an even distribution of cases in the different age-groups up to 15 years, but there were considerable local variations. Despite the low incidence rate there is much that suggests that immunization coverage is still low in some areas. If the goal of eliminating indigenous measles by 1990 is to be achieved then urgent action is required to improve immunization coverage. Intensification of preventive measures around individual cases is also necessary. Suggestions for measures to further reduce the incidence rate of measles in Norway are included in the conclusions to the article.
Insights
Norway
Area of Science:
- Epidemiology
- Public Health
Context:
- Measles incidence in Norway during the first half of 1988.
- Reporting methodology changes impacting data comparability.
- Regional variations in measles occurrence, including an epidemic in Finnmark and an outbreak in Troms.
Purpose:
- To analyze the measles incidence rate in Norway for the first six months of 1988.
- To assess the preventability of measles cases and identify areas with low immunization coverage.
- To recommend strategies for measles elimination in Norway by 1990.
Summary:
- The lowest half-yearly measles incidence rate was recorded in Norway (2.6 per 100,000), though data comparability is affected by reporting changes.
- Despite the low national rate, 48% of cases were preventable, with higher rates in Finnmark (77%).
- While serious complications were absent, other complications were unexpectedly high, indicating a need for improved immunization coverage and preventive measures.
Impact:
- Highlights the need for urgent action to improve measles immunization coverage to meet elimination goals.
- Underscores the importance of targeted preventive measures and addressing local variations in vaccination rates.
- Provides insights into measles epidemiology and informs public health strategies for disease control in Norway.
