[Increased incidence of severe Streptococcus group A infections in Noway during the last 10 years. New outbreak 1993-94].
The article summarizes the epidemiology of disease caused by Streptococcus pyogenes in Norway during the last two decades, with emphasis on trends since the late 1980s. The description is based on the National Notification System for Infectious Diseases, and on microbiological data. The nationwide outbreak in 1987-88, caused mainly by M-1 organisms, was followed by several years with remarkably low incidences of invasive disease. However, since late in 1992 there has again been a nationwide outbreak that reached even higher numbers of invasive cases than the one in 1988. While 106 cases of systemic group A streptococcal disease were recorded in 1988, the numbers for 1993 and 1994 were 143 and 188 respectively (population 4.3 million). No change has taken place in the laboratory-based notification system that could explain the observed phenomena. Previously seldom observed clinical manifestations, such as fulminant septicaemia, necrotising fasciitis and pneumonia with empyema, were again recorded; as during the 1988 outbreak.
