Ongoing rubella outbreak in Austria, 2008-2009

Abstract:
Since October 2008, a total of 143 cases of rubella have affected the two Austrian provinces Styria and Burgenland. The index case occurred in mid-October 2008, but was not notified to the public health authorities until February 2009, when the Austrian Agency for Health and Food Safety was asked to investigate a cluster of 32 rubella cases (24 laboratory-confirmed and eight clinically suspected cases). No case of rubella had been reported in the two affected provinces between February 2007 - when statutory notification for rubella was implemented - and mid-October 2008. 113 of the 143 cases (79%) were confirmed: 101 (89.3% of the 113 cases) clinical-laboratory confirmed and 12 clinical-epidemiological confirmed. Thirty cases fulfilled the criteria of a probable outbreak case only (laboratory results or data on epidemiological link are pending). For 140 outbreak cases data on age was known; the median age was 19 years (range: 2-60 years). 20 cases occurred in soldiers in seven military camps in the area. 55 cases (38.5 %) were female. One case of a laboratory-confirmed rubella infection, affecting an unvaccinated pregnant 18-years old native Austrian in the early first trimenon of pregnancy, led to voluntary abortion
Insights
A rubella outbreak in Austria from October 2008 to February 2009 involved 143 cases, primarily affecting young adults and military personnel. This highlights the need for continued rubella surveillance and vaccination efforts.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- Rubella (German measles) is a contagious viral infection.
- Statutory notification for rubella in Austria was implemented in February 2007.
- No rubella cases were reported in Styria and Burgenland between February 2007 and October 2008.
Purpose of the Study:
- To investigate a rubella outbreak in the Austrian provinces of Styria and Burgenland.
- To characterize the epidemiology of the rubella outbreak.
- To assess the impact of the outbreak on public health.
Main Methods:
- Retrospective analysis of reported rubella cases.
- Laboratory confirmation of rubella infection.
- Clinical and epidemiological investigation of suspected cases.
Main Results:
- A total of 143 rubella cases were reported between October 2008 and February 2009.
- 113 cases (79%) were confirmed, with 101 being clinical-laboratory confirmed.
- The median age of cases was 19 years, with 20 cases in soldiers; one unvaccinated pregnant woman contracted rubella.
Conclusions:
- The outbreak demonstrated the potential for rubella resurgence even after implementation of notification systems.
- The findings underscore the importance of maintaining high vaccination coverage to prevent outbreaks.
- Public health authorities need to remain vigilant for rubella cases, particularly in specific populations like military personnel.
