Influenza – FLU

 

Influenza, also known as the flu, is a contagious disease that is caused by the influenza virus.  Infection with influenza viruses can result in severe illness and life-threatening complications.  However, most people recover within one or two weeks.

 

Symptoms and Diagnosis

When flu viruses enter the nose, throat, or lungs of a person, they begin to multiply, causing symptoms of flu.

Flu usually comes on suddenly and its symptoms may include:

High fever

Headache

Tiredness/weakness, which can be extreme

Dry cough

Sore throat

Runny nose

Body or muscle aches

Diarrhea and vomiting can also occur, but are more common in children.

 

Colds and flu are both highly contagious and in the initial stages a bad cold and a mild case of the flu might seem alike.  However, unlike colds, the flu is a serious illness that can have life threatening complications.
