What You Need to Know About Seasonal Influenza

If you are experiencing flu-like symptoms, please seek appropriate medical care.

If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms).

If you are worried about your symptoms you may want to contact your health care provider who will determine whether influenza testing or treatment is needed. If you experience any of the following warning signs, seek emergency medical care.

In children emergency warning signs that need urgent medical attention can include:

  • Fast breathing or trouble breathing
  • Bluish skin color
  • Not drinking enough fluids
  • Not waking up or not interacting
  • Being so irritable that the child does not want to be held
  • Flu-like symptoms improve but then return with fever and worse cough
  • Fever with a rash

About the Flu

Seasonal Influenza (flu) is a respiratory disease caused by type A influenza virus or type B influenza virus. In the United States, annual epidemics of influenza typically occur during the fall or winter months. 


What are seasonal influenza immunization recommendations?

Routine annual influenza vaccination is recommended for all persons aged ≥6 months.


What are the signs and symptoms of flu in people?

The symptoms can include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with flu. Flu may cause a worsening of underlying chronic medical conditions or cause severe illness.


If you are a health care provider

If you have a fever (100 degrees F or greater) and cough, sore throat, running nose, malaise, headache, vomiting diarrhea or sign/symptoms of influenza please contact your manager prior to reporting to work


How does flu spread?

Flu viruses are spread mainly from person to person through coughing or sneezing of people with influenza. Sometimes people may become infected by touching something with flu viruses on it and then touching their mouth or nose.


How can someone with the flu infect someone else?

Infected people may be able to infect others beginning 1 day before symptoms develop and up to 7 or more days after becoming sick. That means that you may be able to pass the flu to someone else before you know you are sick, as well as while you are sick. Children, especially younger children, might potentially be contagious for longer periods.


How long can viruses live outside the body?

We know that some viruses and bacteria can live 2 hours or longer on surfaces like cafeteria tables, doorknobs, and desks.


If you are a health care provider

  • Get your influenza immunization free of charge through employee health.
  • Wear your PPE to include eye protection and face mask with every patient who may have signs and symptoms related to influenza or respiratory illness.
  • Complete frequent hand hygiene.
  • If you are performing respiratory secretion generating procedures (such as bronchoscopy or intubation) wear your N-95 mask.


What can I do to protect myself from getting sick?

Get your seasonal influenza immunization.


How do I prevent the spread of seasonal influenza?

  • Practice Cough Etiquette: Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • If no tissue available, cough or sneeze into the bend of your arm
  • Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
  • Avoid touching your eyes, nose or mouth. Germs spread this way.
  • Try to avoid close contact with sick people (wear PPE if in health care settings)
  • Frequently clean the environment to reduce the chance of getting contamination from these common surfaces such as door knobs, bed rails, computer key boards, etc.
  • If you get sick with influenza, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
