When the coughing stops is probably a better sign of when a swine flu patient is no longer contagious, experts said after seeing new research that suggests the virus can still spread many days after a fever goes away.
The federal Centers for Disease Control and Prevention has been telling people to stay home from work and school and avoid contact with others until a day after their fever breaks.

It is interesting how the “new Swine Flu” is so genetically different from the H1N1 “seasonal influenza virus”, that still circulates, after two years. Interesting, because the new flu appears to have “reverse engineered itself” to infect humans after incorporating DNA found in avian, swine and human viruses, including elements found in European and Asian swine viruses. It is a mystery how the DNA from the aforementioned viruses managed to combine their proteins with H1N1 flu viruses that emanated from the 1918 Spanish flu, then mix with swine flu genes from pigs, making it possible to infect humans.
