I think TB is an instructive example to look at more closely:
"about
one-third of the world's population has latent TB, which means people have been infected by TB bacteria but are not (yet) ill with the disease and cannot transmit the disease.
People infected with TB bacteria have a 10% lifetime risk of falling ill with TB. However, persons with compromised immune systems, such as people living with HIV, malnutrition or diabetes, or people who use tobacco, have a much higher risk of falling ill."
www.who.int/mediacentre/factsheets/fs104/en/Clearly the immune system is the most important thing in keeping people from becoming ill when exposed to infectious agents. I don't disagree with you in that emotions and mindset can play an important role here.
With Lyme disease some never fall ill from exposure and many can recover with only a short round of antibiotics. However the medical community has taken these two groups of individuals and somehow drawn the conclusion that all people are able to easily clear Borrelia. What remains for some is this this thing called PTLDS that somehow presents exactly like untreated Lyme disease.
In my mind the stubborn resistance to acknowledging the reality of chronic Lyme will become a major chapter in the annals of the scientific blindness.
I think this professor's work is really on the cutting edge of evolutionary biology:
