Isospora infection is a parasitic infection of the intestine caused by the microscopic parasite Cystoisospora belli (used to be called Isospora belli). The parasite may be transmitted by consuming food or water contaminated with the feces of an infected person. Infected persons excrete the immature form of the parasite. The parasite normally takes approximately 1 or 2 days in the environment before it may infect someone else. In rare circumstances, the parasite may develop in less than a day. This virus spreads by indirect means, such as contaminated food or water. This is due to the parasite’s requirement for time to develop.
On the other hand, oral-anal contact with an infected individual may pose a danger of transmission. Isospora infection may be found all throughout the globe, but it is more common in tropical and subtropical areas.
