Description:International Circumpolar Surveillance (ICS) is a population-based surveillance system for invasive bacterial diseases established in the U.S. Arctic, Northern Canada, Greenland, Iceland, Norway, Finland, and Northern Sweden. Data collection began in 1999 and includes information on disease caused by Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, and groups A and B Streptococcus (GAS, GBS). This report reviews the data collected for the year 2Data on invasive disease with the organism S. pneumoniae are collected from all participating countries. A total of 1,582 cases of invasive pneumococcal disease were identified in 2013. Overall, rates of invasive S. pneumoniae were highest in individuals less than 2 years of age or in persons 65 years and older. Case fatality ratios ranged from 9-16%. Race and ethnicity data are collected only in N. Canada and the U.S. Arctic; rates of invasive pneumococcal disease in Northern Canadian Aboriginal and U.S. Arctic Native populations were 28 and 35 cases per 100,000 population, respectively, which are similar to the 2012 rates in these populations. Pneumonia and bacteremia were the most common clinical presentations; cigarette smoking, alcohol abuse, and chronic lung disease were the most common risk factors. The most common S. pneumoniae serotype in Iceland was 19A, in Greenland it was serotypes 4 and 10A, in N. Canada it was serotypes 4 and 7F, in N. Sweden it was 22F and in the U. S. Arctic the most common serotypes were 16F and 22F.
Data on invasive disease due to H. influenzae, N. meningitidis, and groups A and B Streptococcus are currently collected in Greenland, Finland, Northern Canada, Northern Sweden and the U.S. Arctic; Norway also contributes data on cases of N. meningitidis and H. influenzae. A total of 177 H. influenzae cases, 50 N. meningitidis cases, 268 GAS cases, and 302 GBS cases were reported in 2013. In general, the highest rates of disease for all organisms occurred in N. Canada Aboriginal or Alaska Native persons less than two years of age and persons 65 and older.
ICS is a cooperative project funded by the Coordinating Center for Infectious Diseases, Centers for Disease Control and Prevention, Atlanta, Georgia, and by the Public Health Agency of Canada in Ottawa, Canada.
