Flu activity in mid-Michigan is getting fast and furious.
"We have had people in non-stop since 8:00 this morning," said Ruby Rodgers, Disease Control Manager at Ingham County Health Department.
"It's a race against the virus," said Dr. Dean Sienko of the Ingham County Health Department.
For the Ingham County Health Department, the influx of flu patients is evident, and Dr. Sienko says it's all attributed to swine flu.
"We are seeing quite a bit of influenza like illness for this time of the year, almost all of that is the swine flu," Sienko said.
"We are seeing an increase in flu suspects," said Robin Roach of Sparrow Hospital's Infection Prevention and Epidemiology.
Roach says they're also seeing cases of flu-like symptoms soar to heights that are uncommon this early in the year.
"We believe that 99 percent of what we're seeing in terms of the positive test results are probably as a result of H1N1 influenza, not seasonal flu," Roach said.
But the health department is expecting doses of the swine flu vaccine to be shipped by the end of this week at the latest.
"We will be distributing it to the priority areas, to pediatric offices, OB/GYNS, others who hit the priority group," Sienko said.
As expected, doctors say they are in fact seeing more swine flu cases in particular populations.
"This swine flu appears to be effecting the younger population, for the most part when I'm looking at the average age of the people getting ill, it's about 20 years of age," Roach said.
But until the vaccine arrives, it's back to the basics, hand washing and staying home.
