Blastocystis Hominis Transmission: How Does it Spread?
The transmission of Blastocystis hominis, a microscopic parasite, is believed to occur when a person ingests contaminated food or comes into contact with contaminated stool. This can happen, for example, when changing diapers in a daycare setting. However, the exact rates of transmission between animals and humans, humans and animals, and humans and humans are still not fully understood. Some studies suggest that individuals living in close proximity to pets and farm animals may have a higher prevalence of Blastocystis hominis infections.
Risk Factors
Factors that increase the likelihood of blastocystis infection include living or traveling in areas with inadequate sanitation. Additionally, individuals with weakened immune systems are more susceptible to contracting the parasite. The risk of infection also rises when consuming unsafe drinking water or coming into contact with contaminated animals.
