I encountered a fellow who has Lyme disease, and he stated several troubling "facts."
Lyme disease is likely sexually transmitted after it enters we humans. There is a lot of antidote evidence, one of a couple gets it, the other later comes down with it, without ever recalling of noticing a tick.
Serious Lyme disease may be man made variant.
It seems there are two strains, one mildish, one often severe. The severe variant seems have first been found adjacent to Plum Island biological warfare that worked on Lyme Disease as a biological weapon but the USA. Did it escape? After the lab was closed?
