Swine flu caused three in five influenza deaths in 2009

About 50 persons died from the flu and 3 out of 5 of these deaths were caused by the swine flu. It was mainly younger people who died from the swine flu.

A total of 41 300 persons died in 2009, 21 500 of which were women. Cardiovascular diseases and cancer were the most common causes of death, at 30 per cent and 25 per cent respectively.

Some causes of death in 2009

Age difference of flu deaths

While deaths caused by the seasonal influenza hit the elderly in particular, it was mainly younger people who died from the swine flu (the average age was approximately 40). Most of them suffered from additional serious illnesses. There was no sign of a general mortality increase in the population during the swine flu period.

The number of deaths caused by swine flu differs between Statistics Norway and The Norwegian Institute of Public Health (NIPH). The reason for that is:

The Cause of Death Registry is the source for the numbers registered by Statistics Norway. These are based on death certificates and autopsy reports in a total of 32 deaths. These certificates and reports state that the swine flu (influenza A H1N1) is the underlying cause of death for these persons in 2009. The source of NIPH is physicians and laboratories. A total of 29 notifications from local physicians reported laboratory confirmed influenza deaths in 2009. Differences in the inclusion criteria is the reason for different numbers in NIPH and Statistics Norway.

About 570 deaths by suicide were reported in 2009. Next to the year 1999 this is the highest number since 1993.

Decrease in cardiovascular diseases

The mortality by cardiovascular diseases is decreasing. With regard to gender, a reduction has been in progress for men for almost 40 years, and almost 50 years for women. The decrease in cancer mortality continues.

Fewer deaths at home

Eight out of ten deaths happened in hospitals and in nursing homes. Thirty-six per cent of the deaths occurred in hospitals and 43 per cent in nursing homes. In the years 2000–2009 there were fewer deaths in hospitals and more deaths in nursing homes.

Increase in missing death certificates

A total of 630 death certificates were missing in 2009, 260 of these were deaths abroad. Most of the increase is due to some irregularities in forwarding the death certificates from the county Hedmark.

Deaths in Norway with missing death certificates have an age and gender distribution in line with the average and it is likely that the mortality pattern of these deaths differs little from deaths registered by death certificates. When it comes to deaths abroad, men are over-represented and the average age is lower. Most of these deaths are probably accidental deaths.
