Validating disinfection for SARS-CoV-2 in a senior living facility

Note from the Author: This white paper resulted from a collaboration between LuminUltra, IWC Environmental Solutions, and Source Molecular.

SARS-CoV-2, the virus which causes COVID-19, is highly contagious and has been shown to remain viable on surfaces for several days after exposure depending on the surface material.  

This is particularly alarming as the asymptomatic infection rate has been reported to range from 18-78% and these carriers could be vectors of community transmission.    

Senior living facilities have been shown to be particularly vulnerable to COVID-19. This white paper looked to validate cleaning and disinfection strategies used in a senior living facility in the midwestern USA where nine residents had recently confirmed positive for COVID-19. Environmental testing was done by swabbing various surfaces and processing them using quantitative polymerase chain reaction (qPCR) technology. 

After discovering the outbreak and moving the COVID-19 patients to a hospital, the individual resident rooms remained vacant and uncleaned for approximately four days until a biohazardous cleaning team was able to clean and disinfect.    

Find out how qPCR technology is effective at testing for the presence of SARS-CoV-2 and how it assisted in identifying and validating: 

  • The presence of the virus in vacant resident rooms even 8 days after  
  • The presence of the virus after standard cleaning protocols was performed 
  • The importance of an effective disinfection procedure for virus eradication
