Inactivation rate coefficient of viruses and virus surrogates in sewage (a) and pasteurized sewage (b) based on reported log inactivation values. When multiple log inactivation values were reported, an average inactivation rate coefficient value was determined. SARS: Severe acute respiratory syndrome coronavirus (SARS-CoV), 229E: Human coronavirus 229E, FIPV: Feline infectious peritonitis virus, PV1: Poliovirus 1, MHV: Mouse hepatitis virus, TGEV: transmissible gastroenteritis virus, Phi6: Pseudomonas phage Phi6, MS2: Enterobacteria phage MS2. Rectangles refer to non-enveloped viruses (PV1 and MS2), while the rest are for enveloped viruses or enveloped virus surrogates. Note that the value for SARS in (b) is for sterilized water.
