Variable chlorine efficacy across strains may affect water treatment reliability; leaves open optimal protocols and supports testing diverse environmental isolates.
There is considerable variability in disinfection inactivation kinetics among and within enterovirus serotypes, highlighting the need to include diverse environmental isolates in future disinfection studies.
Meister et al. (2018) studied Enterovirus B disinfection resistance. Disinfection (UV254, sunlight, free chlorine, chlorine dioxide, heat) vs. Laboratory strains and MS2 bacteriophage was evaluated on Inactivation rate constants. Free chlorine exhibited the greatest (10-fold) variability in inactivation kinetics between different enterovirus strains, whereas inactivation by UV254 differed only subtly.
