Information about the virus, precautions to take, and educational activities for your children if their schools are closed

In April 2009, an outbreak of H1N1 (swine flu) broke out in many countries across the globe. On June 11, 2009, the World Health Organization (WHO) declared that a global pandemic of novel influenza A (H1N1) was underway. By then, H1N1 had spread to more than 70 countries. The Centers for Disease Control (CDC) correctly predicted that there would be more cases, more hospitalizations, and more deaths associated with the pandemic in the United States into the fall and winter. However, by mid-October, the nation's worst fears failed to materialize. The CDC reported that between April and mid-October, about 22 million Americans had contracted H1N1, 98,000 cases required hospitalization, and about 3,900 people died from H1N1-related causes. Though these numbers seem high, they are lower than those normally associated with seasonal flu. There was a shortage of vaccines in early- and mid-fall, but by late November, some 61 million doses were available or had been administered.
