Can any kind of infection cause crp to be high in blood?

Yes: CRP is an "acute-phase reactant". This means any stress - chronic illness, psychological, or acute physical (like infection) can increase the crp. It is part of a cascade of chemicals that increases your body's inflammatory response. However, when you are free of acute illnesses and have chronic illnesses and psychological stresses under control, the CRP may be elevated but not significantly high.
