JK, i think you mean underdiagnosed. It is a worldwide epidemic, over 200,000 new cases in the US alone every year. Even the most knowledgeable heavy metal physicians are saying that the Borrelia spirochete (Lyme) now outweighs the impact of mercury etc.
And it's not just Lyme, it's all the co-infections with it.
I've been detoxing metals, doing candida diets for years with no improvement at all, and this year found out from a physician who has expertise in all these problems that i have major neuroborreliosis and co-infections, so no wonder metal detox hasn't helped.
