Contents
Escherichia coli
Hosts
Animals and humans
Transmission/Exposure Routes
Fecal-oral route, and most illness has been associated with eating undercooked, contaminated ground beef, swimming in or drinking contaminated water, and eating contaminated vegetables; but direct person-to-person contact can also spread infection (www.azdhs.gov)
Case Fatality Ratios
| Case Fatality Ratio | Pathway/conditions | Population | References |
| 8% | Neonatal Meningitis | Not Reported | (Medscape) |
| 3-5% | Developed hemolytic uremic syndrome | Not Reported | (www.azdhs.gov) |
| <1% | Not Reported | Overall | (www.azdhs.gov) |
Incubation Period
The incubation time for E. coli O157:H7 can be from 2 to 8 days, but it usually ranges from 3 to 4 days (www.azdhs.gov).
Burden of Disease
The incidence of E. coli O157:H7 and non-O157 infection per 100,000 population in 2008 is 1.12 and 0.45 (CDC MMWR).
Duration of infectiousness and disease
Symptomology
Severe stomach cramps, diarrhea, and vomiting are common symptoms of E. coli O157:H7 infections. Fever can occur but is usually less than 38.5˚C. Symptoms generally subside within 5-7 days, although more extreme cases do exist. [1]
Excretion Rates (see Exposure)
Immunity
Microbiology
Gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (Wikipedia).
Environmental Survival
Recommended Dose Response Model
Dose response models for Escherichia coliBeta-Poisson, α is 0.16, N50 is 2.11E+06
Exponential, k is 2.18E-04
