Asthma-Related Information
       The information in this paragraph comes from the Center for Disease Control (CDC).   State-specific self-reported prevalence rates ranged from 5.8%-7.2% in 1998.  Defining asthma can be quite tricky since many of the symptoms of asthma are also symptoms of other illnesses and allergies.  Of the fifteen million Americans who have asthma, many are children.  Asthma is the most prevalent chronic disease among children.  In 1990, asthma-related health costs were 6.2 billion dollars.  The projected costs for 2000 are 14.5 billion dollars.  This increase in health costs is primarily a result of a continual increase in the prevalence of asthma.  Any links between asthma and industrial pollution are unclear.  Although particulate matter (PM) and sulfur dioxide (SO2) are thought to play a role in causing asthma.
