An interesting point noticed when reading about developing Rheumatology practice in Vietnam, and papers on % of population suffering from RD:
China has fewer than UK and other Western countries’ populations while Vietnam has high prevalence of RD (and combines modern medicine approaches with ancient ones).
Q: Why does it occur more in tropical Vietnam? Is their soil depleted of boron? Is it bacterial ie due to mycoplasma/microbiome issues?
