Swine Flu
This little piggy had swine flu, this little piggy had none.
Children, parents and educators will enjoy using these educational
plush toys to teach about hygiene, disease and the human body. Each
microbe comes with a description of the disease it causes or function it
performs. Use these fun, non-threatening toys to emphasize the
importance of washing hands and preventing sickness in social settings. Surface wash, air dry. FACTS: Swine
flu is an influenza that usually affects pigs. However, just as the
common, seasonal flu that affects humans is constantly mutating (as our
immune systems and vaccines compromise weaker strains), swine flu is
always trying to improve itself so that it can become more virulent,
spread faster-and even associate with better company.
Occasionally, a pig-headed virus such as Influenza A (H1N1) actually
succeeds and begins infecting other species-like humans. Naturally this
raises philosophical questions as to whether it is still a swine flu;
since it's new, it isn't widespread in the porcine population-and
anyway, once it is affecting other species, well....
Nevertheless, once a virus such as swine flu makes the jump to another
species, the health risks in the new population are substantial. In the
original host-population, some immunities generally exist against the
original strain, and these immunities are often at least partially
effective against new mutations. In a new host, however, there may be
no natural immunity to the original strain and no partial immunity to
the new strain, so the virus can spread rapidly. In addition, a virus
that produces mild effects in one species may be life-threatening in
another-so catastrophic health consequences can result.
Fortunately, swine flu viruses are generally fragile, and in most cases
basic health precautions (such as hand-washing and avoiding close
contact with those who are ill) significantly reduce the chance of
infection. Nevertheless, the dangers of future mutations and infections
will continue to abound until, well, pigs fly. |
