Influenza

Influenza (commonly called "the flu") is a contagious illness caused by viruses that infect the respiratory system (nose, throat, bronchial passages, and lungs). It can cause mild or serious illness, and in some people it can be life threatening.  The flu is different from the common cold.

Some people are more likely to get flu complications that may result in hospitalization and occasionally death.  Examples of these complications are pneumonia, bronchitis and ear infections.  Flu can make chronic health problems worsen, for example asthma.

The influenza virus is very contagious, and spreads easily from person to person. It can be treated with specific antiviral medications, but the medicine is only effective if started in the first 2 days of symptoms. However, most healthy young adults recover without any treatment other than those for relief of symptoms.  The best way to prevent the flu is by getting vaccinated (the flu shot) each year.

Symptoms:
The symptoms of the flu usually start suddenly, and worsen more quickly than those of a cold. The main symptoms of the flu are fever (temperature over 100° F OR 37.7 C), muscle or bodyaches, and harsh cough. Other symptoms may include runny nose, sore throat, headaches, fatigue, and occasionally vomiting or diarrhea, though these last symptoms are more common in children.


Duration
The symptoms of the flu usually improve after 4-5 days, but may take up to 2 weeks to completely resolve.

Self-Treatment:
If you suspect that you have the flu, or are diagnosed with influenza by your healthcare provider, you should follow these instructions:

1)      Practice self-isolation until the fever is gone for 24 hours without the use of medication

  • Stay home, do not go to class, and do not go out
  • Stay 6 feet away from others
  • Cover your cough
  • Wash your hands frequently, especially after coughing
  • E-mail, text, or call your professors to explain your absence from class

2)      Self-care measures:

  • Take your temperature with a thermometer (you can get one from the Health Center pharmacy)
  • If your temperature is greater than 100°F or 37.7°C, stay in bed
  • Drink plenty of non-alcoholic fluids
  • Take acetaminophen (Tylenol), or ibuprofen (Advil) as directed on the bottle label to reduce any fever or body aches
  • Over-the-counter cough or cold medicines may be used if you wish, but will not make the flu go away or shorten the duration of symptoms
  • Eat normal foods as tolerated, there is no need for any specific restrictions
  • Watch for signs of more severe illness (below)

3)      Signs of severe illness that mean you should be seen by a healthcare provider:

  • Difficulty breathing, or shortness of breath
  • Severe or persistent vomiting
  • Bluish or gray skin color
  • Dehydration (not drinking enough fluids)
  • Pain or pressure in the chest or abdomen
  • Flu symptoms improved but then returned with fever and worsening cough

If any of these symptoms occur, you should be evaluated at the Health Center the same day, or if the Health Center is closed, at a local urgent care center or hospital emergency room.
