The Snohomish Health District reports a Bothell woman in her 30s died last weekend after contracting pneumonia following an influenza diagnosis. She had underlying health conditions.
The woman's death brings the statewide total to at least six influenza deaths reported.
Health officials warn that the flu season is coming unusually early. The H1N1 virus is also targeting younger adults who are not normally considered to be at risk.
Unlike the last outbreak of H1N1 Swine Flu in 2009, health officials say there's no shortage of vaccine.

At Evergreen Health in Kirkland, Dr. Frank Reido says six influenza patients have been admitted in critical condition in the past two weeks alone.
Three of those patients have died.
"These are mostly healthy adults with no previously known health issues," says Reido. "It's highly unusual."
Free Flu shots will be available in the coming weeks.
In Snohomish County, the health district offers the immunization on Friday: 10 a.m. to noon at Everett Station, 3201 Smith Avenue on Saturday and 3:30 to 5:30 p.m. at Comcast Arena, 2000 Hewitt Avenue.
