2009 flu pandemic in the United States by state

The United States experienced the beginnings of a pandemic of a novel strain of the influenza A/H1N1 virus, commonly referred to as " swine flu", in the spring of 2009. The earliest reported cases in the US began appearing in late March 2009 in California, then spreading to infect people in Texas, New York, and other states by mid-April. Early cases were associated with recent travel to Mexico; many were students who had traveled to Mexico for Spring Break. This spread continued across the country's population and by the end of May there were approximately 0 confirmed cases throughout all 50 states.

On April 28, 2009, the director of the Centers for Disease Control and Prevention (CDC) confirmed the first official US death of swine flu, a 23-month-old toddler from Mexico who died on April 27 while visiting Texas.
By June 24, 132 deaths had been attributed to the virus.
As of January 11, 2010, at least 554,000 deaths were attributed to the virus worldwide, and at least 12,469 deaths in the US were confirmed to be due to the virus. The CDC suspects, however, that the total number of deaths in the US is much higher than the official total, as some deaths probably went unconfirmed.

Alabama

On May 2, 2009, the Alabama Department of Public Health confirmed the first case of H1N1 (swine flu) in Madison, Alabama, one of two probable cases previously identified at an elementary school in Madison. As a result, all public schools and most private schools and daycare centers in Madison County, Alabama, including the cities of Huntsville and Madison, closed for two days. After meeting with the state public health officer on May 3, 2009, all Madison city elementary schools were to be closed through May 13, 2009, but were reopened after the CDC updated its guidance to schools.

As of December 5, 2009, the Alabama Department of Public Health reports 2453 confirmed and 36 deaths from swine flu. As of January 9, 2010, Alabama was the only US state reporting widespread A/H1N1 flu activity.

Alaska

On May 10, 2009, the Alaska state Division of Public Health reported the state's first probable case of swine flu in a crew member of a Royal Caribbean cruise ship traveling in Alaska waters. On May 12, they confirmed that the woman had been infected with swine flu but they do not consider it to be Alaska's first case because she became ill before entering state waters.

As of December 5, 460 cases of swine flu and 11 deaths were confirmed in Alaska.
On July 27, Alaska health officials confirmed the first H1N1-related death.

Arizona

As of October 31, the Arizona Department of Health Services had reported a total of 6,302 confirmed cases of H1N1 infection since April 2009, with at least one case reported in each of the state's 15 counties. 786 of the cases had resulted in hospitalization of the patient, and 81 deaths were associated with H1N1 infection in that period of time. Of the H1N1 associated deaths reported in the state, 72% suffered an underlying medical condition (asthma, lung or heart conditions, cancer, metabolic disorders, pregnancy, immunosuppressive disorders, neurologic diseases or other chronic diseases) at the time of death.

On April 28, the first cases of H1N1 influenza infection in Arizona were confirmed in four school-aged patients in the Phoenix metropolitan area. The schools attended by the patients were immediately closed following recommendations from the CDC; after only 3 days, however, local authorities reopened the schools, stating that the H1N1 flu appeared to be no more deadly than the seasonal flu. School closures in the area have since been eliminated in favor of simply sending the infected children home, resulting in slightly elevated absence rates statewide. The first death in the state due to H1N1 swine flu complications was reported by the Maricopa County Department of Public Health on May 14.
As of January 15, Arizona has reported 142 deaths due to confirmed A/H1N1 influenza, including at least 2 in 2010 alone.

Arkansas

During the 2009-2010 flu season, the Arkansas Department of Health reported 53 confirmed cases of swine flu. Four of the cases were from Camp Robinson, a US Army National Guard base in North Little Rock, Pulaski County.
