The Norwegian Board of Health and Welfare announced Friday that they had detected a new strain of the Swine Flu Virus. The new virus had been found in three out of 70 Swine Flu patients, of which two had died.
“The symptoms are mild for most, but could prove serious for some. This virus seems to reach further down in the lungs,” said Geir Stene-Larsen, the general secretary of the Board at a press conference on Friday afternoon.
The same strain has also been detected in Sweden. But Maria Brytting, microbiologist at the Swedish Institute of Infectious Disease says that the flu virus is changing constantly all over the world.
“We have seen the same two viruses, in very ill patients, in mildly affected patients and in perfectly healthy individuals. So it is hard to say if this really is the cause of a more dangerous disease. We have not come to the same conclusion as the Norwegians – that this mutation is the cause of the increased numbers of severely ill in Norway, “she said to Swedish news agency TT.
Brytting also pointed out that the WHO have continuously said that no more aggressive strains have been found so far and that it is important to stress that the vaccine against Swine Flu gives protection against this strain.
