Facts about the flu

  • Although each flu season is different, approximately 5 to 20 percent of the population will get the flu each year. Approximately 36,000 of those who get the flu will die from it or from complications.
  • What causes influenza?
  • The influenza virus is generally passed from person to person by airborne transmission such as sneezing or coughing but the virus can also live for a short time on objects such as doorknobs, pens, pencils, keyboards, telephone receivers, and eating or drinking utensils. Therefore, it may also be spread by touching something that has been handled by someone infected with the virus and then touching your own mouth, nose, or eyes.

What are the symptoms of the flu?

The following are the most common symptoms of the flu. However, each individual may experience symptoms differently. Influenza is called a respiratory disease, but the whole body seems to suffer when a person is infected. People usually become acutely ill with several, or all, of the following symptoms:

  • high fever
  • headache
  • sneezing (at times)
  • cough, often becoming severe
  • severe aches and pains
  • fatigue for several weeks
  • a sore throat (in some cases)
  • extreme exhaustion

Fever and body aches usually last for three to five days, but cough and fatigue may last for two weeks or more. Although nausea, vomiting, and diarrhea may accompany the flu, these gastrointestinal symptoms are rarely prominent. “Stomach flu” is an incorrect term sometimes used to describe gastrointestinal illnesses caused by other microorganisms.
The symptoms of the flu may resemble other medical conditions. Always consult a physician for an accurate diagnosis.

How to prevent the flu
A new influenza vaccine is introduced each September. Centegra Health System has an adequate supply of the vaccine now ready to distribute. It is usually recommended for specific groups of people, as well as for persons who want to avoid having the flu. Following these precautions may also be helpful:

  • When possible, avoid or limit contact with infected persons.
  • Frequent hand washing may reduce, but not eliminate, the risk of infection.
  • A person who is coughing or sneezing should cover his/her nose and mouth with a disposable tissue to limit spread of the virus.

When should I get a flu shot?

Centegra Health System and the Centers for Disease Control recommend getting the flu shot every year, between September and mid-November, before the flu season hits usually December to April. The flu shot takes one to two weeks to become effective and is available today at many Centegra Health System facilities. Although there are many new medications designed to treat flu symptoms and even shorten the duration of the illness, the flu vaccine still offers the best protection against the flu.

If I get the flu shot, can I still get the flu?

Every year, the flu shot “cocktail” changes to combat the current strains of influenza affecting the population. The World Health Organization (WHO) monitors flu outbreaks worldwide and recommends appropriate vaccine compositions to be used for the next year. However, sometimes a strain may appear that was not included in the flu vaccine. People who have had the flu shot tend to have milder symptoms if they contract the flu.
