As the world becomes more populated, there appear to be more allergic reactions to common substances. This might not be quite true, and much of it is due to better record keeping and reporting by health agencies. People still die today from bee stings, but that does not mean the number of people allergic to them has risen. The agencies that track this information have found better ways to get reports about it, and electronic data systems help them record and disseminate the information more efficiently.
While it might seem nice to imagine that there are no more allergies than ever before, people appear to believe they are allergic at some point in their life to some item. Controlling allergies is important for future health concerns, and even comfort in everyday life can be a factor. Learning more about allergies for those who suffer and those who might eventually contract them is a good idea.
