The number of swine flu cases in Arizona continues to increase. As of this past Wednesday, the day the Arizona Department of Health Services reports the number of flu cases each week, the ADHS reported a total of 1,480 swine flu cases in Arizona.
The ADHS figures show 13 cases of swine flu cases in Yavapai County.
Steven Everett, county epidemiologist, said the 13 swine flu cases the ADHS reports for the county spent time in hospitals.
"There are a lot of cases out there of swine flu that will never be reported because they didn't go to a hospital," he said.
Leslie Horton, Yavapai County Community Health Services public information officer, said the swine flu cases in the county have been in people 25 and younger.
Everett said the swine flu is striking in all parts of the county, on both sides of the mountain, and from Mayer through Prescott.
During the week of Sept. 6-12, a Centers for Disease Control and Prevention spokesman said a review of the key indictors found that influenza (swine flu) activity continued to increase in the United States compared to the prior weeks. Below is a summary of the most recent key indicators:
Visits to doctors for influenza-like illness are increasing nationally. The CDC spokesman said visits to doctors for influenza-like illness are more frequent than normal for this time of year and are up for the fifth consecutive week. This is very unusual for this time of year, he said.
Total influenza hospitalization rates for adults and children are similar to or lower than seasonal influenza hospitalization rates depending on age group, but are higher than expected for this time of year.
The proportion of deaths attributed to pneumonia and influenza was low and within the bounds for this time of year.
Twenty-one states are reporting widespread influenza activity at this time. They are: Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Illinois, Kansas, Kentucky, Louisiana, Maryland, Minnesota, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, Pennsylvania, South Carolina, Tennessee, and Virginia.
Almost all of the influenza viruses identified so far are 2009 H1N1 influenza A viruses. These remain similar to the viruses chosen for the 2009 H1N1 vaccine, and remain susceptible to the antiviral drugs oseltamivir and zanamivir with rare exceptions.
