Influenza, commonly known as the "flu," is an extremely contagious respiratory illness caused by influenza A or B viruses. Flu appears most frequently in winter and early spring. The flu virus attacks the body by spreading through the upper and/or lower respiratory tract.
Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. But now, thanks to some well-preserved snot, that may be getting easier.
This week, a look a discovering flu strains.
TTFN, Fred.
