NorovirusNorovirus Cruise Ships – 2002 Previously Known as Norwalk – like Viruses. Changed in 2002 1968 – 1972 Outbreak of “Winter Vomiting Disease” in Norwalk, OH Acute gastroenteritis – “stomach flu” or “24 hour bug” Explosive vomiting, watery (non bloody) diarrhea, abd cramps, HA,
body aches, low-grade fever. 24-60 hours #1 Cause of Foodborne Illness in US, causing about 2/3 of all
foodborne illness – 23 million infections, 50,000 hospitalizations, 300 deaths / year.
Transmission fecal-oral (food and water) – Direct & Indirect, also airborne (inhale and swallow droplets)
Highly transmissible – as few as 10 viral particles may cause infection. Only the “Common Cold” is reported more frequently.
Virus is stable on environmental surfaces – Non enveloped virus. Quats work by disrupting the viral envelope and are ineffective on non enveloped viruses.

DefinitionsDefinitions
A "disinfectant" is a substance that destroys or eliminates a specific species of infectious or other public health microorganism, but not necessarily bacterial spores, in the inanimate environment. *
A "sanitizer" is a substance that significantly reduces the bacterial population in the inanimate environment, but does not destroy or eliminate all bacteria or other microorganisms. *
(* EPA March 2002)
Two Levels of Disinfection for Two Levels of Disinfection for Environmental ServicesEnvironmental Services
Intermediate Disinfection (ILD) – Inactivate Mycobacterium Tuberculosis var. Bovis in addition to all other organisms below it.
ex. 3% Hydrogen Peroxide, 70% Isopropyl, Phenolics, Iodophors, and the other ready to use tuberculocidal solutions
Low-Level Disinfection (LLD) – Inactivate most forms of bacteria, some fungi, some viruses.
ex. Quaternary Ammonium Solutions
