Noroviruses die, with survival times varying in different environments.
Norovirus is a single-stranded RNA virus, often causing viral infectious diarrhea, manifested as watery or yellow dilute watery stools, several times a day or dozens of times a day, and in severe cases, there can be severe dehydration, shock and other consequences. And it is very infectious, resistant to heat and acid, and resistant to ether and commonly used disinfectants (such as alcohol, acetic acid, etc.).
In general, norovirus can survive in the temperature range of 0 ℃ ~ 60 ℃, in pH 2.7, room temperature environment for 3 hours, 20% ether 4 ℃ can survive for 18 hours, can tolerate the concentration of chlorine ions in ordinary drinking water (free chlorine 0.5 ~ 1.0mg / L).
However, norovirus can be inactivated in 30 minutes in a high concentration of chlorine containing 10mg/L.
