Flu is more widespread across the nation, but the number of hard-hit states has declined, health officials said Friday. Officials at Harton Regional Medical Center stated Friday afternoon that the emergency room has “seen a large number” of cases of the flu so far this year. Nationally, 20 children have died from the flu. According to officials at Harton, there have been more cases seen in the emergency room of the flu involving children than adults so far. Most people with flu have a mild illness. But people with severe symptoms should see a doctor. They may be given antiviral drugs or other medications to ease symptoms. It’s not too late to get vaccinated. Many county health clinics are even offering the vaccine for free.
