H1N1 Influenza
The 2009 Swine flu outbreak:
An outbreak of swine flu or influenza A virus subtype H1N1 began in Mexico in April 2009 and then it was reported in parts of the world. Soon it became apparent that, a pandemic was "imminent". For describing the spread of a disease two words namely, " pandemic" and "epidemic" are used. Aandemic means the prevalence of an infectious disease over a much larger region than in case of an epidemic.
The 2009 putbreak was first detected in Mexico City on 18th March where there was a sudden increase in cases of influenza-like illness.
What causes a pandemic?
To cause an influenza pandemic the virus must be entirely new or one which has not circulated widely in the human population and for which there is no vaccine. In a pandemic not all people become infected, but nearly all become susceptible to infection.
Influenza A viruses
Viruses are a large group of infectious agents ranging from 10 to 250 nanometers in diameter and composed of a protein sheath surrounding a nucleic acid core. Viruses are capable of infecting all animals, plants and bacteria.
It is interesting to note that though influenza is an important disease of humans, the disease-causing virus wa first isolated from poultry.
