reaction has occurred, very small quantities of
a substance may produce respiratory illness, such
Wheezing, chest tightness and breathlessness.

Once a person is sensitized, continued exposure
can result in permanent damage to his lings and
increasingly severe symptoms. People with Rhinitis

likely to become worse and can be triggered by
other things such as tobacco smoke, general air
pollution or even cold air.
