Contamination may be spread by flies or when changing diapers (nappies). Person-to-person transmission within households and day-care facilities or among other close contacts whenever hand washing after defecation is inadequate. Person-to-person transmission of Shigella species, which have a low infectious dose, occurs frequently, particularly in areas with poor sanitation and hygiene. Sexual transmission has been observed in homosexual males. Day care centers, prisons, mental institutions, nursing homes, and military camps.

Diagnosis of shigellosis is made by stool cultures. Treatment with appropriate antibiotics shortens the duration of the illness and eliminates the Shigella organism from the stool, thereby limiting further transmission of the disease. See also dysentery. Shigellosis is an infection of the intestine caused by a group of bacteria called Shigella. Inadequate sanitation and hygiene favour transmission. Shigellosis is an infection by bacteria of the genus Shigella that causes severe abdominal symptoms, including diarrhea, dysentery, abdominal cramps, fever, and rectal pain. Shigellosis is highly contagious as exposure to a few organisms can make you sick. It is caused by the bacteria (germs), Shigella. Many cases of shigellosis are the result of overseas travel, but occasional outbreaks occur. Of … Effective antibiotic treatment can decrease the shedding period to only a few days. A chapter is devoted to the laboratory and serological diagnosis of systemic fungal infections. The book can provide useful information to microbiologists, physicians, laboratory scientists, students, and researchers. Why is Shigellosis able to establish itself so easily upon entry? It is a major public health problem in developing countries where sanitation is poor. It is transmitted via contact with contaminated food, water, surfaces or an infected person. Shigellosis. Vomiting (but usually associated with bloody diarrhea) Fever Abdominal cramps. The report presents the first global and regional estimates of the burden of foodborne diseases. The large disease burden from food highlights the importance of food safety, particularly in Africa, South-East Asia and other regions. Community outbreaks have been frequently associated with daycare centers and school attendees [18,19].
