Meningococcal disease in Scandinavia.

Scandinavia (Denmark, Finland, Iceland, Norway, and Sweden) comprises with mutual borders and 22.3 million inhabitants an area where the socioeconomic and cultural conditions are similar. Epidemic diseases, such as meningococcal infection, might therefore be expected to be uniformly distributed. An epidemiological study in the 10-year period 1970-9 shows, however, remarkable differences in the incidence, age, and serogroup and type distribution, as well as in the general dynamics of the disease. Three epidemics, two caused by different serotypes of group B (Norway and Iceland) and one by group A (Finland) occurred within the observation period. The annual overall incidence was generally around 3/100 000 but increased from fivefold (Finland) to eightfold (northern Norway) during epidemics. The epidemic strains caused infection in over 3000 patients and the loss of at least 250 lives. The overall case fatality rate was 8.6% (range 4.1-13.7%). Men were more susceptible and had a worse prognosis than women of the same age group. The group A epidemic in Finland was influenced by a large vaccination campaign, but this possibility was not feasible in the two other epidemics.

A prevalence survey of infections among hospitalized patients in Norway.

The prevalence rates of infections among hospitalized patients in 15 Norwegian hospitals on 28 November 1979 is reported. A total of 7833 patients were included in the study, representing approximately 35 per cent of patients in somatic hospitals in Norway on that day. The prevalence rate of all infections was 17 per cent and for hospital infections 9 per cent. Hospital infections were most frequent in haematology and intensive care departments (23 and 22 per cent respectively) while the lowest rates were found in ophtalmology and psychiatry (2 per cent). Urinary tract infections played a major role both overall (33.5 per cent) and in hospital infections (41.9 per cent). In community acquired infections alone lower respiratory tract infections were slightly more common than urinary tract infections (26.6 per cent of infections versus 24.1 per cent). The study also comprises data on frequency of bacteriological examination in infected patients and on usage of indwelling urinary catheters in patients with urinary tract infections. The rates are compared to studies in other countries. We found the prevalence survey method to be an acceptable way of assessing infection rates among hospitalized patients in Norway. The greatest benefit of the survey is believed to be the ability to increase the awareness of infection problems in hospitals among health personnel.

Principles and practice of control of meningococcal disease in Norway.

An effective control of meningococcal disease must be based on an understanding of the epidemiological situation and knowledge about the natural history of the disease. The relationship between the infecting agent, its source, the route of transmission, and the susceptible host ("the chain of infection") should be defined. After a discussion on principles, the practice of control of meningococcal disease in Norway during the last five years is described. Control measures must at present be directed towards patients and high risk contacts. Control measures also include education of health personnel, information to the public, and research.
