The CDC has stated that the primary transmission of COVID-19 from individual to individual is through respiratory droplets. When individual infected with COVID-19 coughs, sneezes, or talks, these droplets are released and the contaminated droplets can be inhaled or they can land in the noses or mouths of those nearby. The CDC also states that respiratory droplets can land on surrounding surfaces and objects around the individual when they speak or cough.
Some recent studies have indicated that the COVID-19 virus may remain viable and infective on surfaces for hours to days, depending on the type of surface’ material. Thorough cleaning and disinfection of frequently touched surfaces are recommended by the CDC and believed to be essential in preventing the spread of infection.
CDA can also perform Adenosine Triphosphate, or ATP, onsite testing to determine if disinfecting agents and procedures activities are significantly reducing surface contamination and biofilm. This rapid ATP cleaning verification is conducted onsite utilizing an Hygiena ATP Hygiene Monitoring System (SystemSURE Plus) and lab provided ATP swabs. The surface testing is performed to quantify the amount of surface biofilm utilizing Relative Light Units (RLUs) as the unit of measure. ATP collected from the tested surfaces is brought into contact with Hygiena's unique liquid-stable reagent in the testing device. Light is then emitted in direct proportion to the amount of ATP present in the sample, providing information on the level of contamination in seconds.
