"Most people with flu typically do not require emergency care, but this season's disease strain is much more active than previous years", Dr. Paul Kivela, president of ACEP, said in a statement.
"The last few weeks we certainly have seen still sustained activity", he says.
Some researchers say part of the problem may be that most flu vaccine is made by growing viruses in chicken eggs; the viruses can mutate in the eggs, making the vaccine less effective in people.
Insurance, Medicaid and Children's Health Insurance Program (CHIP) is accepted for children's flu shots.
District employees were provided with opportunities to obtain their flu shots in the fall. There have been no supply shortages reported.
But the season started much earlier than usual - the first week of October instead of the end of December, stressed department spokesman Bruce Macfarlane.
The CDC still recommends getting this season's flu shot, even though it's been less effective than usual, because it might reduce the severity of the flu should you contract it.
Overall, the data showed 17,024 new laboratory-confirmed cases of illness during the week ending January 27, bringing the season total to 126,117. Of the 1,206 influenza A viruses that were subtyped, 1,017 (84.3%) were H3N2 viruses and 189 (15.7%) were (H1N1) pdm09 viruses. In the US, said Murti, there have been fewer cases of Influenza B.
Influenza is a highly contagious respiratory illness.
Symptoms of influenza include fever (usually above 102), chills, cough, sore throat, and congestion. But it's not clear the symptoms are caused by the drug, rather than by the flu itself, she said. "During this time of widespread flu activity, we want to remind people to avoid contact with others if you have influenza or an influenza-like illness". So getting sick with one strain of flu won't necessarily protect you from a different strain.
It's not too late to get your shot from your doctor or pharmacy.
Adults aged 65 years and older, people with certain chronic medical conditions, young children and pregnant women are among those at highest risk for serious influenza complications that may lead to hospitalization or death.
Lal mentioned they've barely missed any classes, and suspects it could be due to the flu.
There's no vitamin, herbal potion or other supplement known to prevent or treat the flu, Monto and Munoz said.
Dr. Hawkinson said the flu virus is passed along through coughing, sneezing and poor hand hygiene.
After touching anything, don't put your hands and/or fingers near your face - especially your mouth and nose. They are always there to help and answer any questions you may have.
Frequent hand-washing is also known to be helpful in resisting infection, as well as plenty of rest and good nutrition, according to the CDC.
The more employees who come to work sick with the flu, the greater chances that the flu will spread in your workplace, causing workers to be off from work.
