2009-2010 Flu Pandemic In Norway

The 2009–2010 flu pandemic in Norway marked the initial phase of a new influenza pandemic. This pandemic began in the spring of 2009, the illness appeared in tourists returning from affected areas. By the summer of 2009, local person-to-person transmission within Norway was established. Soon thereafter, the number of patients being tested for swine flu exceeded capacity, and authorities recommended that only patients with severe symptoms be tested. The first Norwegian death from swine flu was reported in early September 2009.

Norway was notable among the Scandinavian countries for a high number of swine flu deaths—29 deaths as of 4 January 2010. All 19 counties of Norway had confirmed cases, and deaths occurred in five of the counties. Only Svalbard (an archipelago midway between Norway and the North Pole) had no reported cases of swine flu. About 10 million doses of flu vaccine were ordered from the pharmaceutical industry when the World Health Organization declared a pandemic. The first vaccination campaign started in Bergen, on 22 October 2009, with several hundred people queuing up. The flu was given widespread media coverage and the Norwegian government published a tally of laboratory-confirmed cases of swine flu, but made clear that this was an underestimation.

Timeline overview

On 25 April 2009, the Norwegian Institute for Public Health increased their level of alert after reports of a severe influenza in Mexico. Three days later, it was considered "highly likely" that the new flu would reach Norway within the next few weeks. The first confirmed Norwegian cases appeared on 9 May 2009, in tourists returning from affected areas. By the summer of 2009, local spread of the influenza was established.

On 9 May 2009, the first confirmed cases were reported in two students from Oslo and Telemark returning from trips abroad. As of early July 2009, there were 42 confirmed cases of swine flu, of which 39 of the people were infected while abroad. In late July 2009, a local outbreak was reported in a summer camp in Western Norway. The number of patients wanting tests for the suspected new flu soon exceeded the capacity to test, and by late July 2009, Norwegian authorities were recommending that only severe and special cases be tested.

Influenza surveillance

The Norwegian government has operated an influenza surveillance system for many years. In this system, 201 selected general practices throughout the country report weekly the percentage of patients given a diagnosis of influenza. The study covers about 15% of the population. The results of the influenza study during the 2009 flu pandemic in Norway are shown in the figure below. The share of doctor contacts that ended in a diagnosis of influenza-like illness shot up to nearly 10% in week 44. The last time this percentage was this high was in the 1999-2000 flu season.

On the basis of the last reported data, as of 4 November 2009, the Norwegian Public Health Institute concluded "the pandemic influenza virus is spreading epidemically in large parts of the country".

Deaths

Scenarios

It was reported that 30% of the population would likely fall ill within six months, and that half of those would be confined to their beds. Ultimately, one out of every two persons would have acquired the disease at some point. This meant that about 700,000 Norwegians would have fallen ill, and in this period, 700 to 3,000 more deaths than a regular influenza season were to be expected.

The worst-case scenario was reported to be that 50% of the population would fall ill within six months, and half of those would be confined to their beds. In this case, 1.2 million Norwegians would have fallen ill in this period and an extra 5,000–13,000 deaths beyond the regular influenza season were expected.

Preparations

Norway had a stockpile of 1.4 million doses of Tamiflu and had ordered 200,000 doses of Relenza.

The Norwegian Institute of Public Health (FHI) announced that it would be only a matter of time before the virus was transmitted within Norway, and that cases of travelers falling ill should be expected within the next few weeks. The main goal was to quickly reduce the spread of the virus in Norway, even so, the closure of public institutions, such as schools and kindergartens, was to be avoided as long as possible.

As of 15 May, the Norwegian government lifted their advisory against travel to Mexico, even so, people with increased risk of infection were advised to reconsider the need to travel.

In early May, Norway pre-ordered 4.7 million doses of the then not-yet-developed ''Swine Influenza vaccine.'' The price was estimated to be $47.5 million. Regarding the order, Health Care Minister Bjarne HÃ¥kon Hanssen said

''The contract we are entering into will make it possible to secure vaccine for the population before a pandemic is declared. For myself and for the government it is important to follow up on the advice from the Pandemic Committee... This is also in line with professional advice from the health institutions.''

Vaccine

As of the fall of 2009, Norway was supplied with 9.4 million doses of the influenza vaccine from GlaxoSmithKline; every Norwegian could be given up to two doses. The vaccine was intended to be ready for use after clinical trials in November or December, however, because swine influenza still was considered to be a mild disease, the influenza vaccine could not be used without approval by the European Medicines Agency (EMEA).

Distribution

Norway had enough vaccine for every citizen by the fall of 2009. Health personnel, as well as people with an increased risk of complications, were advised to receive early vaccinations. The Healthcare Ministry provided recommendations for which groups to prioritize in vaccination distribution.

Outbreak

The Norwegian Institute of Public Health (FHI) updated their homepage with information about the swine flu outbreak in Norway every day at 10:00 ( UTC). FHI believed that the northern hemisphere would not be greatly affected by the virus, with the exception of a few outbreaks in enclosed places (schools and other institutions, cruise ships), followed by a bigger epidemic in the fall or winter.
