When an EVP emerges, Health Canada allows disinfectant manufacturers to reference existing information that we have on file for efficacy claims against non-enveloped viruses. Surface disinfectants that are effective against non-enveloped viruses will probably also be effective against enveloped viruses. The act of targeting inactivates the virus.īecause non-enveloped viruses lack fat-based envelopes, they are more resistant to surface disinfectants. Surface disinfectants target fat-based envelopes. Non-enveloped viruses are more resistant than enveloped viruses. Non-enveloped viruses don't have fat-based envelopes (for example, norovirus and poliovirus). Both the SARS-CoV-2 (the virus that causes COVID-19) and monkeypox viruses are enveloped viruses. How effective a surface disinfectant is depends on 2 things:Įnveloped viruses have fat-based envelopes. Furthermore, few, if any authorized surface disinfectants will have been tested and approved for use against this virus during that time.

When an EVP first appears, there is a period of uncertainty whereby the length of time the virus can survive on surfaces and the contribution of surface transmission to overall disease transmission may not be known. been around but are quickly increasing in numbers or geographic range.Emerging viral pathogens (EVP) are viruses that have either:
