Flu, RSV & COVID Season Facility Cleaning Protocol

Be clear-eyed about this. Influenza, RSV, and SARS-CoV-2 spread primarily through respiratory droplets and aerosols — person to person, through the air. Surface transmission is a secondary route, more significant for RSV and influenza than for COVID, and meaningful for norovirus which is not a respiratory virus at all.

So surface disinfection is one control among several, not the whole answer. Ventilation, filtration, staying home when sick, and hand hygiene do more. What cleaning contributes is real but bounded, and any contractor selling you disinfection as outbreak prevention on its own is overstating it.

Rather than changing everything, increase frequency on a defined short list: entry and interior door handles and push plates, elevator buttons, stair rails, shared kitchen appliance handles and controls, coffee machines and water dispensers, restroom fixtures and dispenser levers, shared desks and hot-desking surfaces, conference room tables and remotes, phones and shared keyboards, and reception counters and card readers.

In an occupied building the highest-value change is a mid-day touchpoint round rather than more work at night. A twenty-minute pass over that list at 11am and again at 3pm does more than doubling the nightly scope, because it interrupts the day's accumulation instead of cleaning after everyone has gone home.

Influenza, RSV, and SARS-CoV-2 are all enveloped viruses and are readily inactivated by most EPA-registered disinfectants, including standard quaternary ammonium products and 70 percent alcohol. You do not need an exotic product; you need the correct contact time.

The trap is that almost every field application fails on dwell time. A quat product with a three-minute contact time sprayed and immediately wiped has not made its label claim. In practice this means either using a product with a genuinely short contact time or working in an order that lets the surface stay wet while you move on.

Current CDC guidance for most non-healthcare settings is that routine cleaning plus disinfection of the areas the person used is sufficient — a facility-wide deep clean after a single case is not evidence-based, and no reputable contractor should sell you one.

The practical sequence: increase ventilation in the space, wait where possible before entering the area, clean then disinfect the person's immediate work area and the shared surfaces they touched, launder any soft items, and resume normal operation. Anyone doing that work should wear gloves and a mask.

Medical and dental practices, childcare, schools, and facilities serving older or immunocompromised populations sit in a different risk category and warrant a genuinely elevated protocol: daily clinical-grade disinfection, mid-day rounds, waiting room and shared seating attention, and documented product and contact time. In those environments, the seasonal step-up should be written into the contract rather than requested reactively.
