Influenza symptoms and causes

 What is Influenza?

 Influenza is also known as flu.  It is a type of disease caused by the RNA virus.  These viruses infect the respiratory tract of animals, birds, and humans.  Usually, people get symptoms like fever, cough, headache, and fatigue due to infection with this virus.  Apart from this, symptoms like nausea, vomiting, diarrhea, and sore throat are also found in some people.


 In most individuals, flu symptoms last for about one to two weeks.  After that the patient becomes healthy.  A person is more seriously ill with a flu infection than other viral respiratory infections (eg colds).  The mortality rate of persons infected with this virus is about 0.1%.

 The above circumstances are common for flu that spreads in a particular season every year.  However, sometimes the flu spreads very severely.  Its severe outbreak comes when such a section of the population is affected by it, whose immunity is very weak.  This is because the flu virus has transformed itself exclusively.  Such situations take the form of an epidemic.
