How many people get Escherichia coli O157:H7?

Incidence (annual) of Escherichia coli O157:H7: estimated 73,000 annual cases of infection in USA (DBMD)
Incidence Rate of Escherichia coli O157:H7: approx 1 in 3,726 or 0.03% or 73,000 people in USA [about data]
Prevalance of Escherichia coli O157:H7: Hemorrhagic colitis infections are not too common, but this is probably not reflective of the true frequency. In the Pacific Northwest, E. coli O157:H7 is thought to be second only to Salmonella as a cause of bacterial diarrhea. Because of the unmistakable symptoms of profuse, visible blood in severe cases, those victims probably seek medical attention, but less severe cases are probably more numerous. Summary of Notifiable Diseases, United States, 1997:MMWR 46(54) (Source: FDA Bad Bug Book) ... An estimated 73,000 cases of infection and 61 deaths occur in the United States each year. (Source: excerpt from Escherichia coli O157:H7 General: DBMD) ... An estimated 73,000 cases occur annually in the United States. Uncommonly reported in patients in less industrialized countries.

What causes Escherichia coli O157:H7?

Causes of Escherichia coli O157:H7: see causes of Escherichia coli O157:H7
Causes of Escherichia coli O157:H7: Infective dose -- Unknown, but from a compilation of outbreak data, including the organism's ability to be passed person-to-person in the day-care setting and nursing homes, the dose may be similar to that of Shigella spp. (as few as 10 organisms). (Source: FDA Bad Bug Book) ... Most illness has been associated with eating undercooked, contaminated ground beef. Person-to-person contact in families and child care centers is also an important mode of transmission. Infection can also occur after drinking raw milk and after swimming in or drinking sewage-contaminated water. (Source: excerpt from Escherichia coli O157:H7 General: DBMD) ... Major source is ground beef; other sources include consumption of unpasteurized milk and juice, sprouts, lettuce, and salami, and contact with cattle. Waterborne transmission occurs through swimming in contaminated lakes, pools, or drinking inadequately chlorinated water. Organism is easily transmitted from person to person and has been difficult to control in child day-care centers. (Source: excerpt from Escherichia coli O157:H7: DBMD)
