Quats are indeed effective against … adenoviruses, enteroviruses, rotavirus, norovirus, influenza virus, severe acute respiratory syndrome coronavirus (SARS-CoV), rhinovirus, chlamydia, HIV, herpes simplex and hepatitis A and B virus.

This article is correct, but the list of pathogens (germs) named are both enveloped and non-enveloped viruses. Enveloped viruses include influenza, SARS-CoV,  chlamydia,  HIV, herpes simplex,  hepatitis B.  Non-enveloped viruses are much harder to kill. These include adenoviruses, enteroviruses, rotavirus, norovirus,  rhinovirus, and  hepatitis A.  There are many quat-based formulations available to deal with both types of viruses, including norovirus and polio.   Read the labels to see if the product is registered to kill a specific pathogen of concern.  Not all products kill all pathogens. Proper application procedures are also crucial for successful eradication of pathogens.
