2009 swine flu outbreak origin
What countries had the 2009 swine flu?
Flu pandemics happen when a new (novel) flu A virus emerges that is able to infect people easily and spread from person to person in an efficient and sustained way, and to which most of the world's population do not have immunity.
The last flu pandemic occurred in 2009 when a novel influenza A (H1N1) virus emerged.Why was the 2009 a H1N1 influenza epidemic considered a pandemic?
Origins of influenza
When did the influenza virus first infect humans? Some scientists hypothesize that humans probably acquired influenza when they began domesticating animals like birds and pigs.
The rise of agriculture and permanent settlements provided ideal conditions to trigger a flu epidemic.What is the origin of the swine flu 2009?
Furthermore, the sequences suggest that viruses with a similar genetic composition to the 2009 pandemic virus have been circulating in pigs in central-west Mexico for more than a decade.
Thus, this region is the most likely source of the virus that started the 2009 pandemic.
