Per
wiki;
Blastocystis naturally live in the gastrointestinal tracts of humans, as well as farm animals, birds, rodents, reptiles, amphibians and fish.
Blastocystis is a very common human parasites globally. In the US, about a quarter of the total population may be infected. In some areas, the infection rate is 100%. High rates of infection are found in individuals who work with animals.
Fecal-oral transmission is the most accepted pathway. (a cat or dog may wash its own anus, and may then lick your face, or your hands)
"dogs could be acting as a large reservoir capable of human infection"
Noel C et al.
Epidemiological studies found that infection is more common in people living in proximity to farm animals or pets
Dovie PW et al.
Are you around animals sometimes?
Infection may cause illness in humans with a poorly functioning immune system. Symptoms associated with the infection are diarrhea, nausea, abdominal cramps, bloating, excessive gas, and anal itching. Most cases of the infection appear to become diagnosed as irritable bowel syndrome. Nitazoxanide treatment seems to be effective, please ask your physician.
I searched for any connection between Blastocystis and hairloss, but i found nothing.
