A Muskogee County boy has been confirmed among three deaths from swine flu between Oct. 25 and Oct. 31.

The Oklahoma State Department of Health listed the death on its Web site Thursday, but the child’s name was not released.

A spokesman for the Oklahoma State Health Department confirmed that the Muskogee County death was a boy under age 19 who had underlying medical conditions. No further information was available.

The three deaths bring the total number of H1N1-related deaths to 20 since the department began surveillance on Sept. 1. Another death occurred in June.

Twelve of the deaths had documented history of underlying medical conditions that may have increased their risk for the illness, including asthma, diabetes, obesity and compromised immune systems.

Health officials say seven of the victims were children under 19, and three of them had underlying medical conditions.

One case involved an infant less than 6 months old.

The Web site also reported 804 cases of influenza-related hospitalizations from Sept. 1 to Oct. 31. Of those, 457, or 57 percent, being under age 19. African American children had the highest number of hospitalizations at 77, followed by Native Americans with 46 and white children, with 37.

Two H1N1 vaccination clinics will be held Saturday.
