While residents were confirmed to have COVID-19, it was important to identify it in the environment to validate the post-disinfecting results. The same sites within the residence were retested one hour after disinfecting to determine if the disinfection process was effective. The presence of the virus Severe Acute Respiratory Syndrome Coronavirus {SARS-CoV-2} was established via culturing the high contact areas and objects within the residence of a confirmed COVID-19 patient.
HOW ESS STEPPED
IN TO HELP.
Twelve high contact sites/objects, both non-porous and porous materials, were selected for testing. The premise was then disinfected with a stabilized chlorine dioxide solution via electrostatic spray device. One hour later the same twelve sites were retested in accordance with procedures provided by Hawk Environmental. This included wiping all test surfaces with sterile gauze moistened with sterile saline. The identical culture procedures were followed. The samples were run through a PCR test regime. Multiple contact sites were positive for COVID-19 and some were suspicious. No other surface reported identification of the virus in the pre-treatment samples. The post-treatment samples were all negative for the virus.
