An outbreak of H1N1 Swine Flu was reported in Mexico in April 2009. By the end of May, it had spread across the U.S., with all 50 states reporting cases.
A 27-year-old woman from northeast Kansas has died from the H1N1 virus.
The Kansas Department of Health and Environment said the woman had underlying health conditions that placed her at greater risk for severe complications of influenza.
Her infection was confirmed Oct. 22, and her death was reported to KDHE on Dec. 16.
KDHE defines northeast Kansas as Marshall, Nemaha, Brown, Doniphan, Riley, Pottawatomie, Atchison, Geary, Morris, Lyon and Douglas counties. A Lawrence-Douglas County Health Department spokeswoman said the 27-year-old was not from Douglas County.
The death brings the state total of confirmed deaths from the H1N1 virus, also known as swine flu, to 23.
