Flu Symptoms & Severity

Influenza (also known as the flu) is a contagious respiratory illness caused by flu viruses. It can cause mild to severe illness, and at times can lead to death. The flu is different from a cold. The flu usually comes on suddenly. People who have the flu often feel some or all of these symptoms:

  • Fever* or feeling feverish/chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle or body aches
  • Headaches
  • Fatigue (tiredness)
  • Some people may have vomiting and diarrhea, though this is more common in children than adults.

* It’s important to note that not everyone with flu will have a fever.

 

Flu Complications

Most people who get influenza will recover in a few days to less than two weeks, but some people will develop complications (such as pneumonia) as a result of the flu, some of which can be life-threatening and result in death.

Pneumonia, bronchitis, and sinus and ear infections are three examples of complications from flu. The flu can make chronic health problems worse. For example, people with asthma may experience asthma attacks while they have the flu, and people with chronic congestive heart failure may have worsening of this condition that is triggered by the flu.

 

People at Higher Risk from Flu

Anyone can get the flu (even healthy people), and serious problems from influenza can happen at any age, but some people are at higher risk of developing serious flu-related complications if they get sick. This includes people 65 years and older, people of any age with certain chronic medical conditions (such as asthma, diabetes, or heart disease), pregnant women, and young children.

 

Flu Severity

Flu is unpredictable and how severe it is can vary widely from one season to the next depending on many things, including:

  • what flu viruses are spreading
  • how much flu vaccine is available
  • when vaccine is available
  • how many people get vaccinated, and
  • how well the flu vaccine is matched to flu viruses that are causing illness.

One study found that during the 1990s, flu-related deaths in the United States ranged from an estimated 17,000 during the mildest season to 52,000 during the most severe season (36,000 average). Over a period of 31 seasons between 1976 and 2007, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people. During a regular flu season, about 90 percent of deaths occur in people 65 years and older.

 

 

Preventing the Flu: Good Health Habits Can Help Stop Germs

 

The single best way to prevent seasonal flu is to get vaccinated each year, but good health habits like covering your cough and washing your hands often can help stop the spread of germs and prevent respiratory illnesses like the flu.

 

Stopping the Spread of Germs at Home, Work & School

 

Good Health Habits

  • Avoid close contact.
    Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.
  • Stay home when you are sick.
    If possible, stay home from work, school, and errands when you are sick. You will help prevent others from catching your illness.
  • Cover your mouth and nose.
    Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.
  • Clean your hands.
    Washing your hands often will help protect you from germs.
  • Avoid touching your eyes, nose or mouth.
    Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or nose.

 

Stop the Spread of Germs

Healthy habits can protect everyone from getting germs or spreading germs at home, work, or school.

Cleaning and disinfecting surfaces and objects that may be contaminated with germs like the flu can help slow the spread of influenza.
