Almost every week I hear of a new promising development in treating/preventing a major disease. But without fail, each of these stories ends with the caveat that more development/testing is needed and it will be 5-20 years until any useful drug can be made available. I find these articles both uplifting and depressing.
So my question is, given the current state of medical research, which major disease is likely to be the next one for which we find a cure or a means for effective prevention? By cure I don’t necessarily mean complete eradication in a sick patient, but at least allowing the patient to lead a relatively normal life to normal life expectancy.
