2009 flu pandemic summary

The 2009 flu pandemic is a pandemic of a strain of A/H1N1 influenza consisting of a genetic reassortment of swine, avian, and human genes. It began in March 2009 in Mexico, before spreading worldwide between April–June 2009. Currently, it has killed at least 13000 people worldwide, though the World Health Organization says the total is probably much higher. So far it has been a mild to moderate pandemic, with most who contract the disease only having a mild febrile illness with joint pains, headache, cough, and fatigue. However, in a small amount of previously healthy young adults, fatal, progressive viral pneumonia develops 3–6 days after symptom onset, which is very atypical for seasonal influenza. As of late December 2009, the pandemic appears to have peaked in the United States, Mexico, and Canada, as well as much of Europe, but is continuing to increase in parts of Africa and Asia.
