Ignorance of that website. That isn't correct. Candida don't get the bloodstream and colonize other body parts. If candida get the bloodstream, you have candidemia that is a critical condition. Sinuses, vagina, ears, skin, etc are exposed areas that get candida by direct contact with the exterior. Colonization of "external" parts is possible when the competitive flora and the immune system don't offer adequate protection. You will find many no-medical websites telling candida get the bloodstream, even some who say they can see candida in a "live" blood analysis under microscopy. That isn't correct. To detect candida in the blood is necessary advanced medical tests. In the past, many invasive candidiasis cases were fatal because the delay obtaining a positive result, still many are fatal. Do you think a simple look under microscopy can detect candida in the blood ???
After you continue reading, you will realize how many myths about this syndrome are circulating in the web.
I hope this help.
