The flu



It causes severe illness and life threatening complications in many people. Symptoms of influenza come on suddenly and can include fever, chills, muscle aches, runny nose, cough and stomach upsets.

People of all ages can get the flu. However, children, the elderly, and people with weakened immune systems are most susceptible and more likely to develop serious complications. In the United States, flu season runs from October to May, with most cases happening between late December and early March.

What is the cause of influenza?

Influenza can be caused by different strains of the influenza virus. There are three different types of flu viruses: influenza A, B, and C all of which cause illness in humans.

What are the symptoms?

Influenza symptoms can include fever, headache, muscle pain, runny nose, sore throat, extreme tiredness and cough. Children may also experience nausea, vomiting or diarrheoa. Although infections from other viruses may have similar symptoms, those due to the flu virus tend to be worse.

Symptoms can begin about 1 to 4 days, or an average of 2 days. It mostly occurs after a person is first exposed to the flu virus. Fever and other symptoms can usually last up to 7 to 10 days, but the cough and weakness may last 1 to 2 weeks longer.



How does influenza spread?

Influenza spreads easily from person to person through coughing, sneezing or face-to-face contact. You can also get the flu through either handshakes, hugs, saliva, kissing or sharing drinks.

The virus can also spread when a person touches tiny droplets from a cough or a sneeze on another person or object and then touches their own eyes, mouth or nose before washing their hands.

How can you prevent influenza?

The first and most important step in preventing flu is to get a flu vaccine each year. The annual flu vaccine is for everyone 6 months of age and older. It’s usually offered between September and mid-November.

People who got the vaccine one year no longer has its protection the following year. That’s because the protection wears off and flu viruses change. This is why the vaccine is updated each year to include the most current strains of the virus.

  • Washing your hands regularly with saop and water
  • Promptly disposing of used tissues in a well covered bin
  • Cough and sneeze into your shirt sleeve rather than your hands
