The virus that causes COVID-19 is spread from person to person and by contact with surfaces. The virus is expelled in large numbers when people sneeze and cough. A sneeze may produce some 40,000 droplets of saliva with each carrying up to two million virus particles for a total potential delivery approaching 100 billion virus particles in a single sneeze from an infected person.
Geosyntec has developed a validation approach for disinfection programs which includes sampling and testing to identify whether the surfaces in our client’s facilities test positive or negative for the virus. This approach can be tailored to each facility and provides our clients with verification data in a summary report indicating if and where virus particles are detected. In the case of detections, the report provides recommendations for further disinfection of areas with positive test results.
Geosyntec has developed protocols to sample various surfaces (e.g., desks, countertops) using composite wipe sampling. Our SARS-CoV-2-specific virus analytical testing in our SiREM genetics lab allows us to collect wipe samples preserved on site and shipped to our laboratory to determine the efficacy of the disinfection process and provide trust-building confirmation that facilities are properly cleaned.
Geosyntec's Integrated Approach from Virus Sampling to Confirmation Reporting
Our approach for disinfection programs includes wipe sampling and testing to identify whether the surfaces in our client’s facilities test positive or negative for the virus. This approach is tailored to each facility and provides owners or operators with the information necessary to make informed decisions regarding next steps to best manage their concerns associated with COVID-19.
