CARSON CITY, Nev. (AP) - Flu season isn't over in Nevada, with health officials reporting an increase in the number of deaths and widespread activity.
In northern Nevada, The Washoe District Health Department says 18 death certificates issued in the second week of the year listed pneumonia or influenza as a contributing factor. Those cases accounted for 13 percent of total deaths reported that week, way above the epidemic threshold set by the National Centers for Disease Control and Prevention.
Five deaths were reported previously in Washoe County.
Nine people have died in southern Nevada so far this season.
The predominant strain is H1N1, known as swine flu. In 2009, a swine flu pandemic killed more than 150,000 worldwide.
The CDC lists Nevada flu activity as high.
