Erratum

In the article appearing on page e355, volume 32, number 9, several errors in the text occurred. Percent signs were incorrectly used when per mille signs were appropriate in some instances magnifying the mortality rates significantly. Below are the corrected sentences in which percent signs are replaced by per mille signs.

Abstract, Results, 1st sentence: “Childhood mortality due to infectious diseases decreased by 89%, from 0.12‰ in 1969 to 0.013‰ in 2004, and neonatal mortality by 69%, from 0.50‰) to 0.16‰.”

Materials and Methods, 3rd paragraph, 1st sentence: “Mortality rates were calculated in proportion to those at risk of dying (ie, all living children in the same age group) and rounded to deaths per 1000 children (‰).”

Results, Childhood Mortality due to Infections, 1st paragraph, 2nd sentence: “Infection mortality declined by 89%, from 0.12‰ (95% CI:0.10–0.15‰) in 1969 to 0.013‰ (95% CI: 0.007–0.023‰) in 2004.”

Results, Neonatal Mortality From Infections, 1st paragraph, 2nd sentence: “…it did show a significant general decline by 69%, from 0.50‰ (95% CI: 0.35–0.70‰) in 1969 to 0.16‰ (95% CI: 0.07–0.30‰) in 2004.”

Discussion, 1st paragraph, 3rd sentence: “…and infection mortality among the same age group in the United States declined by 30% between 1980 and 1992, from 0.30‰ to 0.21‰.”

Abstract

Background:

Our aim was to evaluate changes in infectious disease mortality in children in Finland from 1969 to 2004. We especially wanted to find out whether infection mortality could be further reduced by means of existing vaccines not included in national vaccination program.

Methods:

We analyzed infectious disease mortality in Finland using data obtained from the official Cause of Death statistics for 1969 to 2004. Annual mortality rates were calculated in proportion to those at risk of dying. Infection mortality rates were calculated separately for neonates and children who were 1 month to 15 years.

Results:

Childhood mortality due to infectious diseases decreased by 89%, from 0.12% in 1969 to 0.013% in 2004, and neonatal mortality by 69%, from 0.50% to 0.16%. Pneumonia, central nervous system infections and septicemia were the most common fatal infections in childhood. There were slightly more deaths due to all infections and respiratory tract infections in years marked by epidemics of respiratory syncytial virus. We estimated that pneumococcal conjugate vaccines would have prevented 2 deaths annually in our population, rotavirus vaccines 1 to 2 deaths, influenza vaccine 1 death and varicella vaccine 0.7 death.

Conclusions:

We found that even though mortality from infectious diseases in childhood decreased markedly during the period concerned, it could have been further reduced by means of existing vaccines. Even though the number of deaths prevented would have been small, the number of years of life saved would have been great because the life expectancy of children is long.
