Question
What are the dose-response functions of pathogens in drinking water?
Answer
Rationale
Data
| Pathogen | Reference |
| Campylobacter | [1] |
| Rotavirus | [2] |
| Norovirus | [3] |
| Cryptosporidium | [4] |
| Giardia | [5] |
| E.coli O157:H7 | [6] |
| Obs | Pathogen | Function type | Function | Rname | Unit | Param1 | Param2 |
|---|---|---|---|---|---|---|---|
| 1 | Campylobacter | Beta Poisson approximation | 1-(1+Dose/Param2)^-Param1 | f.beta.poisson.approx | No unit | 0.024 | 0.011 |
| 2 | Rotavirus | Exact beta Poisson | 1-exp(-(Param1/(Param1+Param2))*Dose) | f.exact.beta.poisson | No unit | 0.167 | 0.191 |
| 3 | Norovirus | Exact beta Poisson | 1-exp(-(Param1/(Param1+Param2))*Dose) | f.exact.beta.poisson | No unit | 0.04 | 0.055 |
| 4 | Cryptosporidium | Exact beta Poisson | 1-exp(-(Param1/(Param1+Param2))*Dose) | f.exact.beta.poisson | No unit | 0.115 | 0.176 |
| 5 | Giardia | Exponential | 1-exp(-Param1*Dose) | f.exponential | No unit | 0.0199 | 0 |
| 6 | E.coli O157:H7 | Exact beta Poisson | 1-exp(-(Param1/(Param1+Param2))*Dose) | f.exact.beta.poisson | No unit | 0.157 | 9.16 |
