Estimates of measles case fatality ratios: a comprehensive review of community-based studies.
BACKGROUND: Global deaths from measles have decreased notably in past decades, due to both increases in immunization rates and decreases in measles case fatality ratios (CFRs). While some aspects of the reduction in measles mortality can be monitored through increases in immunization coverage, estimating the level of measles deaths (in absolute terms) is problematic, particularly since incidence-based methods of estimation rely on accurate measures of measles CFRs. These ratios vary widely by geographic and epidemiologic context and even within the same community from year-to-year. METHODS: To understand better the variations in CFRs, we reviewed community-based studies published between 1980 and 2008 reporting age-specific measles CFRs. RESULTS: The results of the search consistently document that measles CFRs are highest in unvaccinated children under age 5 years; in outbreaks; the lowest CFRs occur in vaccinated children regardless of setting. The broad range of case and death definitions, study populations and geography highlight the complexities in extrapolating results for global public health planning. CONCLUSIONS: Values for measles CFRs remain imprecise, resulting in continued uncertainty about the actual toll measles exacts
Effectiveness of measles vaccination and vitamin A treatment
Background The current strategy utilized by WHO/United Nations Children's Fund (UNICEF) to reach the Global Immunization Vision and Strategy 2010 measles reduction goal includes increasing coverage of measles vaccine, vitamin A treatment and supplementation in addition to offering two doses of vaccine to all children
Does it really matter where you live? A panel data multilevel analysis of Swedish municipality-level social capital on individual health-related quality of life
We test whether individual health status is related to area-level social capital measured by rates of voting participation in municipal political elections, controlling for personal characteristics, where health status is measured by mapping responses to interview survey questions into the generic health-related quality of life measure (HRQoL) the EQ-5D in order to derive the health state scores. The analysis is based on unbalanced panel data from Statistic Sweden s Survey of Living Conditions (the ULF survey) and a 3-level multilevel regression analysis, where level 1 consists of a total of 31,585 observations for 24,419 individuals at level 2 nested within 275 Swedish municipalities at level 3. We find that the health state scores increase significantly with municipality election rates. This result is robust to a number of measurement and specification issues explored in a sensitivity analysis. However, almost all variation in health status exists across individuals (more than 98 ), which demonstrates that even if social capital (and other contextual variables) may be significant it is of less importance, at least at the municipality level in Sweden.
