Many who died of swine flu also had pneumonia. Scientists now know why the two diseases have become such a deadly combination.
These are American scientists who have tried to understand why pneumonia makes swine flu so dangerous. About half of those who died from swine flu also had pneumonia.
To find out why researchers have infected a number of mice with either the regular seasonal flu or the A (H1N1) virus that causes swine flu.
Damage the protective cell layers
When the mice fell, they were also infected with Streptococcus pneumoniae, the same bacterium that causes pneumonia.
All mice with only normal influenza and pneumonia survived. In the other group, it was the opposite. Everyone is dead.
When the researchers studied the lungs, it turned out that the small lungs were severely affected and that the protective layers of bronze epithelial cells were completely lost in dead mice.
The researchers concluded that swine flu, unlike the common flu, damages the protective cell layers of the lungs and exposes the body's ability to repair these cells in the event of illness. This allows the bacteria to invade the body in a completely different way from the "normal" flu.
