whatever the trigger or ongoing infection or whatever, the one thing in common is we all have a crapped out immune system.
If we can get it functioning properly then all these infections shouldnt be a problem or only need short courses of antivirals and or antibiotics?
I dont think they are going to find one cause, but i think they will need to group people into subsets, maybe using what infections they have or other dysfunction found. Also some may fit the hit and run theory too.
I think subsets because we know that certain people make good improvement with antivirals that fit the profile. We know people who make good improvement from antibiotics if they fit the right profile and get treated with the correct abx for the correct amount of time. Because 1 particular treatment doesnt help everyone doesnt mean its not helpful. Theres also that group that slowly improve or even fully recover without any aggressive type of treatment.
I also think 100% recoveries from av's or abx are probably rare because of something wrong with the immune system, if its damaged during the course of the illness or during the initial trigger or some other reason then its going to be hard to rid many of these infections for good and certain stresses may cause relapses as its an extra burden on the immune system.
At the end of the day i dont think we are going to find a cookie cutter theory or treatment to fit all, i think it has to be tailored to the individual( probably through trial and error) and this is what makes us so difficult for doctors to treat or research to study us.
