On August 10th, 2010, the World Health Organization declared the Swine flu pandemic officially over. Swine flu is the H1N1strain of influenza virus; previous outbreaks of the disease have been traced to bird reservoirs and to various locations in Asia, prompting the nickname "Asian bird flu." H1N1 proved lethal in large populations of pigs as well, and is therefore sometimes called "Swine flu." Moving forward from the point, the only real world-wide preventative measure taken against the spread of H1N1 was the incorporation of a weakened form of this virus strain into the seasonal flu vaccine.
However, in what can be described as health officials' worst-case scenario, H1N1 has reemerged in full force in a Utah high school, Duchesne High School. As noted in class, one of the key troubles with sicknesses like swine flu (or Ebola) is that many of the symptoms are nonspecific; indeed, some can simply result from overexertion or tiredness.
The CDC is confident, however, that this is an isolated incident, and has moved forward with a campaign to rapidly vaccinate the surrounding community.
