Viruses are infectious agents that require host cells to reproduce. A building-cleaning claim should identify the specific intended application rather than imply that all viruses behave alike.
What this means at your property
Product performance depends on the organism claim, surface and use conditions. A general statement that a room was cleaned does not establish that a particular disinfection procedure was performed or that transmission risk has been eliminated.
What should a provider document?
Ask for the product, relevant label claim, surfaces included and use instructions followed. Keep individual health questions with healthcare professionals and avoid treating a cleaning record as a medical assurance.
