Are there long term consequences to a Shigella infection?
Persons with diarrhea usually recover completely, although it may be several months before their bowel habits are entirely normal. About 3% of persons who are infected with one type of Shigella, Shigella flexneri, will later develop pains in their joints, irritation of the eyes, and painful urination. This is called Reiter’s syndrome. It can last for months or years, and can lead to chronic arthritis which is difficult to treat. Reiter’s syndrome is caused by a reaction to Shigella infection that happens only in people who are genetically predisposed to it. Once someone has had shigellosis, they are not likely to get infected with that specific type again for at least several years. However, they can still get infected with other types of Shigella. http://www.cdc.gov/ncidod/dbmd/diseaseinfo/shigellosis_g.
