Morgellons Aspergillosis?
Although provocative, Your post did not cite the origins of the statements. For all we know, you heard them from your 7 year old sister.
So I did some due diligence and am pasting some info below. Aspergillus has been known to be a pathogen of humans for a long time...like forty years. It CAN opportunistically infect HIGHLY immune-compromised people. One ref I found was based the autopsy results on a 41 year old leukemia patient.
The article below describes patients who were infected while undergoing bone marrow transplants and organ transplants...i.e. people whose immune systems have been INTENTIONALLY, HARD-CORE weakened..
A favor: Please Give citations/links/names of the people who originally made the claims, and explain the the connection between aspergillus flavius 36 and morgellons symptoms
The first linked article below even discusses effective treatments, assuming you can get access to them. But I'd rather have spent my morning differently. I also found articles about blood tests to detect infection, see below.
