I am interested in finding out whether our governments keep statistics on chronic diseases in the population. Initially, I thought "of course they do" but it seems that only some disease statistics are kept. Cancer statistics are easy to find, but what about other diseases that may be connected to HGRVs such as Parkinsons disease? Chronic disease statistics do not seem to be recorded. We are used to being told that no-one knows exactly how many people have ME. How can a government tell whether there is a growing health problem if they do not keep health statistics for chronic illnesses?
