Input: The most common strain of influenza this year is H3N2 (A)  which was covered by this yearâs flu vaccine. While strains can still mutate in individual cases and render the vaccine ineffective for some people  the flu vaccine can also help lessen the severity of illness in some of these cases  said  Dr. Robert Citronberg  infectious disease physician with Advocate Health Care .
At Lutheran General Hospital in Park Ridge   Citronberg  has seen a steady influx of patients with the flu  which presents  itself  with symptoms including high fever  chills  muscle aches and fatigue   he  said.
âPeople who have genuinely true influenza say that they feel like they got run over by a truck â  Citronberg  said.
An anti-viral prescription medication known as Tamiflu is available to both children adults suffering from the flu. Doctors recommend plenty of rest  drinking fluids and staying away from other people  since people with the flu are typically contagious for about seven days   Citronberg  said.
