Preliminary data on the survival length of enteroviruses in nonalcoholic beverages. Inactivating action of some medicinal herb infusions.

Vaccinal poliovirus type 1, Coxsackie B3 virus and echovirus type 1 survived in mineral water, camomile infusion and coffee for over 20 days. In contrast, Chinese tea, lime and mint infusions had a possibly transient inactivating effect on the same enterovirus strains. There was a direct relationship between the concentration of the infusions and their inactivating action. The vaccinal poliovirus was more sensitive than Coxsackie and echoviruses to the inactivating action of the infusions.
