SITUATION
In late 2019, an outbreak of respiratory illness in Wuhan, China was identified. It is now understood that this outbreak is associated with a Novel Coronavirus that is now identified as COVID-19. Coronaviruses are of significant concern owing to the fact they are zoonotic in nature, meaning they can infect humans and animals1. Prior to the identification of COVID-19, there were six (6) strains of Coronavirus capable of infecting humans with only two (2) strains capable of causing severe disease; severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV)1.
BACKGROUND
In 2003, when SARS-CoV arrived in Canada, infection prevention experts released training bulletins to support in combatting the deadly respiratory disease. Originally, as an unidentified virus, infection prevention experts looked to Health Canada for guidance with respect to supporting evidence needed to make recommendations for cleaning and disinfection. In cases of emerging viral pathogens, Health Canada’s Broad Spectrum Virucide claim2 requirement may be used to determine expected efficacy of a disinfectant against the virus. This guidance is based on a hierarchy of susceptibility of viruses to disinfectants, recognizing that a product with efficacy against non-enveloped viruses will also be effective against enveloped viruses, which are much more readily inactivated.
Accelerated Hydrogen Peroxide® (AHP®) became the recommended disinfectant of choice, resulting in the distribution of a Training Bulletin4. In a recently published study, AHP® was included among the disinfectants that have been shown to have proven efficacy against various strains of Coronavirus. In fact, the AHP® technology carries efficacy claims against five (5) different strains of Coronavirus including MERS-CoV.
When it comes to managing the transmission of Coronavirus, thoroughly cleaning and disinfecting environmental surfaces with a safe and effective disinfectant that carries a short contact time, like AHP®, will support in ensuring facilities have a cleaning and disinfection program that will support their infection prevention needs.
IMPLICATONS FOR AHP®
As seen with Coronaviruses, viral diseases previously known to infect only animals will continue to evolve and broaden their host range to humans. From our experiences with SARS-CoV, MERS-CoV and now COVID-19 we know that infection prevention and control is not just a local issue, and that routine cleaning and disinfection is becoming increasingly important as pathogens continue to cross borders.
